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 0.2. 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.
