TLV431: Low Voltage Precision Adjustable Shunt Regulator
For complete documentation, see the data sheet
Product Description
The TLV431 series of parts are precision low voltage shunt regulators that are programmable over a wide voltage range of 1.24V to
16V. The TLV431A series features a guaranteed reference accuracy of 1.0% at 25 °C and 2.0% over the entire industrial
temperature range of -40 °C to 85 °C. For TLV431B series, the accuracy is 0.5% and 1.0%, respectively. For the TLV431C series,
the accuracy is 0.2% and 0.5%, respectively. These devices exhibit a sharp low current turn-on characteristic with a low dynamic
impedance of 0.20 <FONT FACE=SYMBOL>W</FONT> over an operating current range of 100mA to 20mA. This combination of
features makes this series an excellent replacement for zener diodes in numerous applications circuits that require a precise
refrence voltage. When combined with an optocoupler, the TLV431 can be used as an error amplifier for controlling the feedback
loop in isolated low output voltage (3.0V to 3.3V) switching power supplies. These devices are available in economical TO-92 and
micro size TSOP-5 and SOT23-3 packages.
