Output Current in Excess of 1.0 A No External Components Required Internal Thermal Overload Protection Internal Short Circuit Current Limiting Output Transistor SafeArea Compensation Output Voltage Offered in 2% and 4% Tolerance Available in Surface Mount D2PAK and Standard 3Lead Transistor Although designedprimarily as a fixed voltage regulator, these devices can be used withexternal components to obtain adjustable voltages and currents. With adequate heatsinkingthey can deliver output currents in excess of 1.0 A.
These regulators employ internal current limiting,thermal shutdown, and safearea compensation. These voltage regulators are monolithic integrated circuits designed asfixedvoltage regulators for a wide variety of applications including local,oncard regulation. Values of less than 0.1 F could cause instability. These two digits of the type number indicate nominal voltage.Cin is required if regulator is located anappreciable distance from power supplyfilter.CO is not needed for stability however,it does improve transient response.
Heatsink surface (shown as terminal 4 incase outline drawing) is connected to Pin 2. The input voltagemust remain typically 2.0 V above the outputvoltage even during the low point on the inputripple voltage.XX, A common ground is required between theinput and the output voltages.
