LM7818A ? LM7824A3-Terminal 1A Positive Voltage Regulator General Description The LM78XX series of three terminal positive regulators are available in the TO-220 package and with several fixed output voltages, making them useful in a wide range of applications.Each type employs internal current limiting, thermal shut down and safe operating area protection, making it essentially inde-structible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.Features O Output Current up to 1A O Output Voltages of 5, 6, 8, 9, 12, 15, 18, 24O Thermal Overload Protection O Short Circuit Protection O Output Transistor Safe Operating Area Protection Ordering Code:Product Number Output Voltage Tolerance Package Operating Temperature LM7805CT r4%TO-220 40q C - 125q C LM7806CT LM7808CT LM7809CT LM7810CT LM7812CT LM7815CT LM7818CT LM7824CT LM7805ACT r2%0q C - 125q C LM7806ACT LM7808ACT LM7809ACT LM7810ACT LM7812ACT LM7815ACT LM7818ACT LM7824ACT

Absolute Maximum Ratings

(Note 1)

Note 1: Absolute maximum ratings are those values beyond which damage to the device may occur. The datasheet specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation outside datasheet specifica-tions.

Electrical Characteristics (LM7805)

(Refer to the test circuits. 40q C T J 125q C, I O = 500mA, V I = 10V, C I = 0.1P F, unless otherwise specified)

Note 2: Load and line regulation are specified at constant junction temperature. Changes in V O due to heating effects must be taken into account separately. Pulse testing with low duty is used.

Note 3: These parameters, although guaranteed, are not 100% tested in production.

Note: To specify an output voltage, substitute voltage value for “XX”. A common ground is required between the Input and the Output voltage. The input voltage must remain typ-ically 2.0V above the output voltage even during the low point on the input ripple voltage.Note: C I is required if regulator is located an appreciable distance from the power supply filter.Note: C O improves stability and transient response.
