THREE–TERMINAL

POSITIVE FIXED

VOLTAGE REGULATORS

STANDARD APPLICATION

A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0 V above the output voltage even during the low point on the input ripple voltage.

Heatsink surface

connected to Pin 2.

Heatsink surface (shown as terminal 4 in

case outline drawing) is connected to Pin 2.

These two digits of the type number indicate nominal voltage.

Cin is required if regulator is located an appreciable distance from power supply filter.

CO is not needed for stability; however, it does improve transient response. Values of less than 0.1 µF could cause instability.

These voltage regulators are monolithic integrated circuits designed as fixed–voltage regulators for a wide variety of applications including local, on–card regulation. These regulators employ internal current limiting, thermal shutdown, and safe–area compensation. With adequate heatsinking they can deliver output currents in excess of 1.0 A. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents.

• Output Current in Excess of 1.0 A

• No External Components Required

• Internal Thermal Overload Protection

• Internal Short Circuit Current Limiting

• Output Transistor Safe–Area Compensation

• Output Voltage Offered in 2% and 4% Tolerance

• Available in Surface Mount D
