LM350

3.0 A, Adjustable Output,

Positive Voltage Regulator

The LM350 is an adjustable three−terminal positive voltage

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

voltage range of 1.2 V to 33 V. This voltage regulator is

exceptionally easy to use and requires only two external resistors to

set the output voltage. Further, it employs internal current limiting,

thermal shutdown and safe area compensation, making it essentially

blow−out proof.

The LM350 serves a wide variety of applications including local,

on card regulation. This device also makes an especially simple

adjustable switching regulator, a programmable output regulator, or

by connecting a fixed resistor between the adjustment and output, the

LM350 can be used as a precision current regulator.
