AP432/AP432A
Adjustable Precision Shunt Regulator
Features
General Description
- Precision reference voltage
The AP432/432A are 3-terminal adjustable
precision shunt regulators with guaranteed stable
AP432 : 1.24V ± 1%
temperature
over the applicable extended
AP432A : 1.24V ± 0.5%
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.
- 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 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.
