AP432/AP432A
ADJUSTABLE PRECISION SHUNT REGULATOR
Features
General Description
• Precision reference voltage
The AP432/432A are 3-terminal adjustable precision shunt
AP432 : 1.24V ± 1%
regulators with guaranteed stable temperature over the
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
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.
• Low output noise
The precise +/- 1% reference voltage tolerance of the
• Packages: SOT23, SOT23R, SOT25, SC59 (W package AP432/432A make it possible in many applications to avoid the
code), SC59 (R package code), SOP-8L and TO92-3L use of a variable resistor, consequently saving cost and
• SOT23, SOT23R, SOP-8L and SC59: Available in
eliminating drift and reliability problems associated with it.
“Green” Molding Compound (No Br, Sb) (Note 1)
