SG140A positve fixed voltage regulator

The SG140A/140 series of positive regulators offer self contained, fixed-voltage capability with up to 1.5A of load current and input voltage up to 50V (SG140A series only). These units feature a unique on-chip trimming system to set the output voltages to within ±1.5% of nominal on the SG140A series and ±2.0% on the SG140 series. The SG140A versions also of.

Features

of thermal shutdown, current limiting, and safe-area control have been designed into these units and since these regulators require only a small output capacitor for satisfactory performance, ease of application is assured. Although designed as fixed-voltage regulators, the output voltage can be increased through the use of a simple voltage divider. The low quiescent drain current of the device insures good regulation when this method is used. Product is available in hermetically sealed TO-257 (isolated), TO-3, TO-66, and TO-39 power packages.
