Integrated Circuit

Positive Adjustable Voltage Regulator,

4.5V to 40V, 45mA

Description

The NTE1928 is an adjustable positive voltage regulator that features fast response to both load

and line transients, freedom from oscillations with varying resistive and reactive loads, and the

ability to start reliabity on any load within rating. This device also contains a biasing circuitry that

removes any minimum load current requirement and at the same time reduces standby current

drain, permitting higher voltage operation.

Features:

D Output Voltage Adjustable from 4.5V to 40V

D Output Currents in Excess of 10A Possible by Adding External Transistors

D Load Regulation Better than 0.1%, Full Load with Current Limiting

D DC Line Regulation Guaranteed at 0.03%/V

D Ripple Rejection on 0.01%V

Note 1. The maximum junction temperature of the NTE1928 is +85°C. For operation at elevated

temperatures, this device must be derated based on a thermal resistance of 230°C/W junc-

tion to ambient, or 25°C/W junction–to–case. Peak dissipations to 1W are allowable provid-

ing the dissipation rating is not exceeded with the power average over a two second internal.
