NTE935

Integrated Circuit

3–Terminal Adjustable Positive Voltage Regulator

1.2V to 32V, 5A

Description:

The NTE935 is an adjustable 3–terminal positive voltage regulator in a TO3 type package capable

of supplying in excess of 5A over a 1.2V to 32V output range. This device is exceptionally easy to

use.

A unique feature of the NTE935 is its time dependent current limiting. The current limit circuitry allows

peak currents of up to 12A to be drawn from the regulator for short periods of time.

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 pin is accidently disconnected.

Normally, no capacitors are needed unless the device is situated far from the input filter capacitors

in which case an input bypass is needed. An optional output capacitor can be added to improve tran-

sient response. The adjustment terminal can be bypassed to achieve very high ripple rejections ratios

which are difficult to achieve with standard 3–terminal regulators.

Features:
