LT1431CZ

V-Ref Adjustable 2.5V to 36V 100mA 3Pin TO-92

Description

The  LT®1431  is  an  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 2.5V and 36V. The nominal internal current limit of 100mA may be decreased by including one external resistor.
