If the usage and operation conditions specified in the datasheet are not met, the wire insulation may be damaged or dissolved.•Do not drop or impact the components, the component may be damaged.•Würth Elektronik products are qualified according to international standards, which are listed in each product reliability report. Würth Elektronik does not warrant any customer qualified product characteristics beyond Würth Elektroniks’ specifications, for its validity and sustainability over time.•The responsibility for the applicability of the customer specific products and use in a particular customer design is always within the authority of the customer. All technical specifications for standard products also apply to customer specific products.Product specific:Soldering:•The solder profile must comply with the technical product specifications. All other profiles will void the warranty.•All other soldering methods are at the customers’ own risk.•Strong forces which may affect the coplanarity of the components’ electrical connection with the PCB (i.e. pins), can damage the part, resulting in avoid of the warranty.Cleaning and Washing:•Washing agents used during the production to clean the customer application might damage or change the characteristics of the wire insulation, marking or plating. Washing agents may have a negative effect on the long-term functionality of the product.•Using a brush during the cleaning process may break the wire due to its small diameter. Therefore, we do not recommend using a brush during the PCB cleaning process.Potting:•If the product is potted in the customer application, the potting material may shrink or expand during and after hardening. Shrinking could lead to an incomplete seal, allowing contaminants into the core. Expansion could damage the components. We recommend a manual inspection after potting to avoid these effects.Storage Conditions:• A storage of Würth Elektronik products for longer than 12 months is not recommended.

KG:1. General Customer ResponsibilitySome goods within the product range of Würth Elektronik eiSos GmbH & Co. KG contain statements regarding general suitability for certain application areas. These statements about suitability are based on our knowledge and experience of typical requirements concerning the areas, serve as general guidance and cannot be estimated as binding statements about the suitability for a customer application. The responsibility for the applicability and use in a particular customer design is always solely within the authority of the customer. Due to this fact it is up to the customer to evaluate, where appropriate to investigate and decide whether the device with the specific product characteristics described in the product specification is valid and suitable for the respective customer application or not.2. Customer Responsibility related to Specific, in particular Safety-Relevant ApplicationsIt has to be clearly pointed out that the possibility of a malfunction of electronic components or failure before the end of the usual lifetime cannot be completely eliminated in the current state of the art, even if the products are operated within the range of the specifications.In certain customer applications requiring a very high level of safety and especially in customer applications in which the malfunction or failure of an electronic component could endanger human life or health it must be ensured by most advanced technological aid of suitable design of the customer application that no injury or damage is caused to third parties in the event of malfunction or failure of an electronic component. Therefore, customer is cautioned to verify that data sheets are current before placing orders. The current data sheets can be downloaded at .3. Best Care and AttentionAny product-specific notes, cautions and warnings must be strictly observed. Any disregard will result in the loss of warranty.4. Customer Support for Product SpecificationsSome products within the product range may contain substances which are subject to restrictions in certain jurisdictions in order to serve specific technical requirements. Necessary information is available on request. In this case the field sales engineer or the internal sales person in charge should be contacted who will be happy to support in this matter.5. Product R&DDue to constant product improvement product specifications may change from time to time. As a standard reporting procedure of the Product Change Notification (PCN) according to the JEDEC-Standard inform about minor and major changes. In case of further queries regarding the PCN, the field sales engineer or the internal sales person in charge should be contacted. The basic responsibility of the customer as per Section 1 and 2 remains unaffected.6. Product Life CycleDue to technical progress and economical evaluation we also reserve the right to discontinue production and delivery of products. As a standard reporting procedure of the Product Termination Notification (PTN) according to the JEDEC-Standard we will inform at an early stage about inevitable product discontinuance. According to this we cannot guarantee that all products within our product range will always be available. Therefore it needs to be verified with the field sales engineer or the internal sales person in charge about the current product availability expectancy before or when the product for application design-in disposal is considered. The approach named above does not apply in the case of individual agreements deviating from the foregoing for customer-specific products.7.

Connect a 0V to 20V, 0.5A power supply across the IN and GND terminals and the load across the OUT and GND terminals. The SHDN pin can be disconnected from IN via JP1 to allow for separate shutdown control via a secondary control line. JP2 can be used to select any of a number of common fixed output voltages, or used in conjunction with ADJ1 to create a custom output voltage using the formula:ADJ1 = (V OUT – 1.22V)/4.93µAOUTPUT CAPACITOR SELECTIONThe output capacitor C3 is a 10µF X7R ceramic chip capacitor. Should a different output capacitor be desired, care must be exercised with the selection. Many ceramic capacitor dielectrics exhibit strong temperature and voltage characteristics that reduce their effective capaci-tance to as low as 10% to 20% of nominal over the full range. For further information, see Linear Technology Application Note 83, “Performance Verification of Low Noise, Low Dropout Regulators,” Appendix␣B, “Capaci-tor Selection Considerations,” reprinted below.CAPACITOR SELECTION CONSIDERATIONSBypass Capacitance and Low Noise Performance Adding a capacitor between the regulator’s V OUT and BYP pins lowers output noise. A good quality, low leakage capacitor is recommended. This capacitor bypasses the regulator’s reference, providing a low frequency noise pole. A 0.01µF capacitor lowers the output voltage noise to 20µV RMS. Using a bypass capacitor also improves transient response. With no bypassing and a 10µF output capacitor, a 10mA to 500mA load step settles within 1% of final value in under 100µs. With a 0.01µF bypass capacitor, the output settles within 1% for the same load step in under 10µs; total output deviation is inside 2.5%. Regulator start-up time is inversely proportional to bypass capacitor size, slowing to 15ms with a 0.01µF bypass capacitor and 10µF at the output.34567Information furnished by Linear Technology Corporation is believed to be accurate and reliable.However, no responsibility is assumed for its use.
