ADJUSTABLE PRECISION

ZENER SHUNT REGULATOR

ISSUE 2 – FEBRUARY 1997

DEVICE DESCRIPTION

The ZHT431 is a three terminal adjustable

sh unt regulat o r off e ring ex ce llen t

temperature stability and output current

handling capability up to 100mA. The device

offers extended operating temperature

range working from -55 to +125°C. The

output voltage may be set to any chosen

voltage between 2.5 and 20 volts by

selection of two external divider resistors.

The devices can be used as a replacement

for zener diodes in many applications

req u i r ing an i m p r ov emen t in zen e r

performance.

FEATURES

• Surface mount SO8, SOT89, SOT223

and SOT23 packages

• TO92 package

• 2% and 1% tolerance

• Maximum temperature coefficient 67

ppm/°C

• Temperature compensated for

operation over the full temperature

range

• Programmable output voltage

• 50µA to 100mA current sink capability

• Low output noise

• Wide temperature range -55 to +125°C

APPLICATIONS

• Series and Shunt regulator

• Voltage monitor

• Over voltage/ under voltage protection

• Switch mode power supplies
