Adjustable Precision Shunt Regulator
AP432
Features
General Description
- Precision reference voltage
The AP432 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\/ (V REF) 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.
B : 1.24V ± 1%
A : 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 precise +/- 1% reference voltage tolerance of the
AP432 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.
- RoHS Compliant & Halogen Free Product
