H432 Series
Adjustable Shunt Regulator
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.
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
