AP431/AP431A

ADJUSTABLE PRECISION SHUNT REGULATOR

General Description

Features

The AP431 and AP431A are 3-terminal adjustable precision

shunt regulators with guaranteed temperature stability over the

applicable extended commercial temperature range. The output

voltage may be set at any level greater than 2.495V (V_REF) up to

36V merely by selecting two external resistors that act as a

voltage divider network. These devices have a typical output

impedance of 0.2Ω. Active output circuitry provides very sharp

turn-on characteristics, making these devices excellent improved

replacements for Zener diodes in many applications.

•

Precision reference voltage

AP431 : 2.495V ± 1%

AP431A : 2.495V ± 0.5%

•

Sink current capability: 200mA

Minimum cathode current for regulation: 300µA

Equivalent full-range temp coefficient: 30 ppm/^oC

Fast turn-on response

Low dynamic output impedance: 0.2Ω

Programmable output voltage to 36V

Low output noise

Packages: SOT23, SOT23R, SOT25, SC59 (W package

code), SC59 (R package code), SOP-8L and TO92-3L

SOT23, SOT23R, SOP-8L and SC59: Available in

“Green” Molding Compound (No Br, Sb) (Note 1)

Lead Free Finish/RoHS Compliant for Lead Free and

“Green” Products (Note 2)

The precise (+/-) 1% Reference voltage tolerance of the

AP431/AP431A make it possible in many applications to avoid

the use of a variable resistor, consequently saving cost and

eliminating drift and reliability problems associated with it.
