HI-SINCERITY Spec. No. : HA200216 Issued Date : 1998.04.08 Revised Date : 2002.08.27 Page No. : 1/4 MICROELECTRONICS CORP. H431AA/BA/CA AJDUSTABLE SHUNT REGULATOR Description The H431 series are three-terminal adjustable regulators with guaranteed thermal stability over applicable temperature ranges. The output voltage may be set to any value between VREF (approximately TO-92 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/°C typical • Temperature compensated for operation over • full temperature range • Low output noise voltage • Fast turn on response Classification Rank A B C VREF 2.495±2% 2.495±1% 2.495±0.5% Absolute Maximum Ratings (Operating temperature range applies unless otherwise specified) Characteristics Cathode Voltage Cathode Current Range (Continuous) Reference Input Current Range Power Dissipation Operating Temperature Range Storage Temperature Range H431AA, H431BA, H431CA Symbol VKA IK IREF PD Topr Tstg Value 37 -100~+150 0.05~+10 770 0~+70 -65~+150 Unit V mA mA mW °C °C HSMC Product Specification HI-SINCERITY Spec.
