1 / 14 page AP431/AP431A ADJUSTABLE PRECISION SHUNT REGULATOR AP431/AP431A Rev. 5 1 of 14 MARCH 2007 www.diodes.com © Diodes Incorporated Lead-free Lead-free • Precision reference voltage AP431 : 2.495V ± 1% 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 • 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) • Lead Free Finish/RoHS Compliant for Lead Free and The AP431 and AP431A are 3-terminal adjustable precision shunt regulators with guaranteed temperature stability over the 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. 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. “Green” Products (Note 2) Ordering Information A P 4 3 1 X XX X Package Packing Blank : SOP-8L SA : SOT23 W: SC59 R : SC59 Q : SOT25 Lead-Free Tolerance: Reference Voltage V : TO92-3L A : +/- 0.5% Blank : +/- 1% L : Lead Free G : Green (Note 1) -7/-13 : Taping -B : Bulk -A : Ammo Box : SOT23R SR (Note 3) Note: 1.
