AP432/AP432A Adjustable Precision Shunt Regulator Features - 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 General Description 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.
