AMS421 - 0.5V SHUNT REGULATOR

General Description

The AMS421 is a four-terminal adjustable open collector shunt regulator with guaranteed temperature stability over the entire range of operation.

The output voltage can be set to any value between 0.5V (VREF) and 15V by adding two external resistors.

Key Features

  • Trimmed 0.5% Tolerance.
  • Wide Operating Current Range 0.1µA to 10mA.
  • Low Reference Input Current 1.5nA.
  • Low Dynamic Output Impedance.
  • Low Output Noise.
  • Nominal Temperature Range to 125°C.
  • Temperature-Compensated: 50ppm/°C.
  • Low supply current: typ. 10µA AMS421 0.5V SHUNT.
