Product Overview

The LT1431 series adjustable shunt Voltage Regulator with 100mA sink capability, 0.4% initial reference voltage tolerance and 0.3% typical temperature stability. On-chip divider resistors allow the LT1431 to be configured as a 5V shunt regulator, with 1% initial voltage tolerance and requiring no additional external components. By adding two external resistors, the output voltage may be set to any value between 2.5 and 36V. The nominal internal current limit of 100mA may be decreased by including one external resistor. A simplified 3-pin version, the LT1431CZ/LT1431IZ, is available for applications as an adjustable reference and is pin compatible with the TL431.
  • Fast turn-on
  • Low reference pin current
  • 0.1Ω Typical dynamic output impedance
  • 1 to 100mA Sink current capability
