Product Description

Description
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.
Features
• 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
• Lead Free packages: SOT25, SC59, SC59R, SOT89-3L and TO92-3L
• SOT23, SOT23R, SOT25, SC59, SC59R, SOP-8L, SOT89-3L, TO92-3L: Available in “Green” Molding Compound (No Br, Sb)
• Lead Free Finish/ RoHS Compliant (Note 1)
