H432 Series H432 Series Pin Assignment Adjustable Shunt Regulator 3 1 Description The H432 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 1.24 or 1.25 volts) and 30 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. 1 3-Lead Plastic SOT-23 Package Code: N Pin 1: Reference Pin 2: Cathode Pin 3: Anode 2 2 Features 1 • 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 3-Lead Plastic SOT-89 Package Code: M Pin 1: Reference Pin 2: Anode Pin 3: Cathode 3 2 12 3 3-Lead Plastic TO-92 Package Code: A Pin 1: Reference Pin 2: Anode Pin 3: Cathode 3 Ordering Information Package VREF 1.24V±2% VREF 1.24V±1% VREF 1.24V±0.5% VREF 1.25V±2% VREF 1.25V±1% VREF 1.25V±0.5% SOT-23 SOT-89 TO-92 H432AN H432AM H432AA H432BN H432BM H432BA H432CN H432CM H432CA H432DN H432DM H432DA H432EN H432EM H432EA H432FN H432FM H432FA Absolute Maximum Ratings (Operating temperature range applies unless otherwise specified) Characteristics Symbol Cathode Voltage Cathode Current Range (Continuous) Reference Input Current Range VKA IK IREF Power Dissipation PD Operating Temperature Range Junction Temperature Storage Temperature Range Topr TJ Tstg Value Unit 30 50 0.05~+10 SOT-23 280 SOT-89 770 TO-92 770 -25~+85 150 -65~+150 V mA mA mW o C C o C o Operating Conditions Characteristics Cathode Voltage Cathode Current Range (Continuous) H432 Series Symbol Min.
