• Manufacturer Part Number: IP431A
• Description: PROGRAMMABLE PRECISION REFERENCE
• Manufacturer: Sony Corporation

DESCRIPTION
programmable shunt regulator diode. The voltage
reference operates as a low temperature coefficient zener
which is programmable between V
using two external resistors. The device has a wide
operating current range of 1 mA to 100mA and a typical
dynamic impedance of 0.2 . Active output circuitry
provides a very sharp turn-on characteristic making these
devices excellent replacements for zener diodes in many
applications. Being a shunt regulator it can be used as
either a positive or negative voltage reference.
