LM338T 1.2V to 32V Voltage Regulator 
Datasheet
Description
A unique feature of the LM138 family is time-dependent current limiting. The current limit circuitry allows peak currents of up to 12 A to be drawn from the regulator for short periods of time. This allows the LM138 to be used with heavy transient loads and speeds start-up under full-load conditions. Under sustained loading conditions, the current limit decreases to a safe value protecting the regulator. Also included on the chip are thermal overload protection and safe area protection for the power transistor. Overload protection remains functional even if the adjustment (ADJ) pin is accidentally disconnected.
Feature
- Output voltage range: 1.24V to 32V
- Input Voltage: 4.2 V ~ 40 V
- Output current in excess of 5A
- PSRR: 75dB ~ 60dB (120Hz)
- Operating Temperature: 0°C ~ 125°C
- Package / Case: TO-220-3
