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

MOTOROLA ANALOG IC DEVICE DATA

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
