ANACHIP AP432RLA

AP432/AP432A
Adjustable Precision Shunt Regulator
„ Features
„ General Description
- 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
- Packages: SOT89, SOT23, SOT25, SOP8 and
TO92
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.
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.

Note 3. Deviation of reference input voltage, VDEV, is defined as the maximum variation of the reference over
the full temperature range.
The average temperature coefficient of the reference input voltage αVREF is defined as:

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 V KA and I KA conditions with CL =0.V BATT and
CL were then adjusted to determine the ranges of stability.
