LM333

3-Ampere Adjustable Negative Regulator

General Description

Features

n Output voltage adjustable from −1.2V to −32V

n 3.0A output current guaranteed, −55˚C to +150˚C

n Line regulation typically 0.01%/V

The LM333 is an adjustable 3-terminal negative voltage

regulator capable of supplying in excess of −3.0A over an

output voltage range of −1.2V to −32V. This regulator is

exceptionally easy to apply, requiring only 2 external resis-

tors to set the output voltage and 1 output capacitor for

frequency compensation. The circuit design has been opti-

mized for excellent regulation and low thermal transients.

Further, the LM333 features internal current limiting, thermal

shutdown and safe-area compensation, making them sub-

stantially immune to failure from overloads.

n Load regulation typically 0.2%

n Excellent rejection of thermal transients

n 50 ppm/˚C temperature coefficient

n Temperature-independent current limit

n Internal thermal overload protection

n Standard 3-lead transistor package

n Output is short circuit protected

The LM333 serves a wide variety of applications including

local on-card regulation, programmable-output voltage regu-

lation or precision current regulation. The LM333 is an ideal

complement to the LM150/LM350 adjustable positive regu-

lators.
