AP431/AP431A
ADJUSTABLE PRECISION SHUNT REGULATOR
Features
General Description
• Precision reference voltage
The AP431 and AP431A are 3-terminal adjustable precision
AP431 : 2.495V ± 1%
shunt regulators with guaranteed temperature stability over the
AP431A : 2.495V ± 0.5%
• Sink current capability: 200mA
• Minimum cathode current for regulation: 300µA
• Equivalent full-range temp coefficient: 30 ppm/oC
• Fast turn-on response
• Low dynamic output impedance: 0.2Ω
• Programmable output voltage to 36V
applicable extended commercial temperature range. The output
voltage may be set at any level greater than 2.495V (VREF) up to
36V 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
• Packages: SOT23, SOT23R, SOT25, SC59 (W package
code), SC59 (R package code), SOP-8L and TO92-3L
• SOT23, SOT23R, SOP-8L and SC59: Available in
“Green” Molding Compound (No Br, Sb) (Note 1)
The precise (+/-) 1% Reference voltage tolerance of the
AP431/AP431A 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.
• Lead Free Finish/RoHS Compliant for Lead Free and
“Green” Products (Note 2)
