NOT RECOMMENDED FOR NEW DESIGN USE AZ431L AP432/AP432A ADJUSTABLE PRECISION SHUNT REGULATOR The AP432 and AP432A 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 1.24V 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 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/AP432A 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. • Precision Reference Voltage • AP432 1.24V ± 1% • AP432A 1.24V ± • Sink Current Capability 200mA • Minimum Cathode Current for Regulation 150uA • Equivalent Full-Range Temp Coefficient 30 ppm/°C • Fast Turn-On Response • Low Dynamic Output Impedance • Programmable Output Voltage to 20V • Low Output Noise • Lead Free packages SOT25, SC59, SC59R and SOT89-3 • Lead-Free Finish RoHS Compliant Notes 1 & 2 • SOT23, SOT23R, SOT25, SC59, SC59R, SO-8 and SOT89: Available in “Green” Molding Compound No Br, Sb • Halogen and Antimony Free. “Green” Device Note 3 Pin Assignments 1 SOT25 Top View 2 SO-8 Top View NC 1 NC 2 CATHODE 3 5 ANODE CATHODE ANODE 2 ANODE 3 4 REF REF ANODE NC 3 SC59 Top View 4 SC59R Top View ANODE 1 3 REF ANODE 1 2 CATHODE 3 CATHODE 2 REF 5 SOT23 Top View 6 SOT23R Top View ANODE 1 3 REF ANODE 1 2 CATHOD 3 CATHODE 2 REF 7 SOT89-3 Top View REF Anode Cathode EU Directive 2002/95/EC RoHS & 2011/65/EU RoHS 2 compliant.
