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.

Note 1. Power dissipation is internally limited, these specifications are applicable for power dissipations
up to 50W.
Note 2. Regulation is measured at constant junction temperature. Changes in output voltage due
to heating effects are taken into account separately by thermal regulation.
