ZTLV431_07 Datasheet, PDF (1/8 Pages) Zetex Semiconductors – 1.24V Cost effective shunt regulator

ZTLV431
1.24V Cost effective shunt regulator
Description
The ZTLV431 is a three terminal adjustable
shunt regulator offering excellent temperature
stability and output current handling capability
up to 20mA. The output voltage may be set to
any chosen voltage between 1.24 volts and 10
volts by selection of two external divider
resistors.
Features
• Low voltage operation V_REF = 1.24V
• Temperature range -40 to 125°C
• Reference voltage tolerance at 25°C
• 0.5% ZTLV431B
• 1% ZTLV431A
• Typical temperature drift
• 4 mV (0°C to 70°C)
• 6 mV (-40°C to 85°C)
• 11mV (-40°C to 125°C
• 100␮A minimum cathode current
• 0.25⍀ typical output impedance
• Adjustable output voltage 1.24V to 10V
The ZTLV431 can be used as a replacement for
zener diodes in many applications requiring an
improvement in zener performance.
The ZTLV431 is available as standard as an
A grade which has an initial tolerance of
1%; a B grade is planned with an initial
tolerance of 0.5%, and all cover the -40°C to
125°C temperature range as standard.
Applications
• Opto-coupler linearization
• Linear regulators
• Improved Zener
• Variable reference
