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 V
REF
(approximately 1.24 or 1.25 volts)
and 30 volts with two external resistors. These devices have a typical
dynamic output impedance of 0.2鈩? Active output circuitry provides a very
sharp turn-on characteristic, making these devices excellent replacement
for zener diodes in many applications.
