ZR2431 - ADJUSTABLE PRECISION ZENER SHUNT REGULATOR

General Description

The ZR2431 is a three terminal adjustable s hu n t r e g u l a t or o f f e r i n g e xc el l e nt temperature stability and output current handling capability up to 25mA.

The output voltage may be set to any chosen voltage between 1.24 and 15 volts by selection of two external divider resistors.

Key Features

  • Surface mount SOT23, SOT223, SOT89 and SO8 packages TO92 package 2.5% and 1% tolerance Maximum temperature coefficient 52 ppm/°C Temperature compensated for operation over the full temperature range Programmable output voltage 100µA to 25mA current sink capability Low output noise.

ADJUSTABLE PRECISION ZENER SHUNT REGULATOR ISSUE 3 DECEMBER 1997 DEVICE DESCRIPTION The ZR2431 is a three terminal adjustable s hu n t r e g u l a t or o f f e r i n g e xc el l e nt temperature stability and output current handling capability up to 25mA. The output voltage may be set to any chosen voltage between 1.24 and 15 volts by selection of two external divider resistors. The devices can be used as a replacement for zener diodes in many applications r e qu i r i n g a n i mpr o ve me nt i n z e ner performance. The ZR2431 is particularly used in the feedback control loop of switch mode power supplies. In this application the device 1.24 volt reference enables the generation of low voltage supplies, typically 3.3 volts or 3 volts.
