AP432/AP432A
ADJUSTABLE PRECISION SHUNT REGULATOR
General Description
Features
The AP432/432A are 3-terminal adjustable precision shunt
regulators with guaranteed stable temperature over the
applicable extended commercial temperature range. The output
voltage may be set at any level greater than 1.24\/ (VREF) up to
20V 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
AP432 : 1.24V ± 1%
AP432A : 1.24V ± 0.5%
Sink current capability: 200mA
Minimum cathode current for regulation: 150µA
Equivalent full-range temp coefficient: 30 ppm/oC
Fast turn-on Response.
Low dynamic output impedance: 0.2Ω
Programmable output voltage to 20V
Low output noise
The precise +/- 1% reference voltage tolerance of the
AP432/432A 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

The areas under the curves represent conditions that may cause the
device to oscillate. For curves B, C, and D, R2 and V+ were adjusted
to establish the initial VKA and IKA conditions with CL=0.VBATT and
CL were then adjusted to determine the ranges of stability.
