HI-SINCERITY MICROELECTRONICS CORP. Spec. No. : IC200401 Issued Date : 2004.03.01 Revised Date : 2008.04.01 Page No. : 1/7 H431 Series ADJUSTABLE SHUNT REGULATOR Description The H431 series are three-terminal adjustable regulators with guarante-ed thermal stability over applicable temperature ranges. The output voltage may be set to any value between VREF (approximately 2.495 volts) and 36 volts with two external resistors. These devices have a typical dynamic output impedance of 0.2Ω. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacement for zener diodes in many applications. Features Programmable output voltage Temperature coefficient is 50ppm/oC typical Temperature compensated for operation over full temperature range Low output noise voltage Fast turn on response Ordering Information H431 Series Pin Assignment 3 12 3-Lead Plastic SOT-23 Package Code: N Pin 1: Reference Pin 2: Cathode Pin 3: Anode ...
