CAT102 - Adjustable Shunt Regulator

General Description

The CAT102 is a low-voltage reference and amplifier.

Designed for the control loop of low-voltage power supplies, the reference voltage has been designed for 600 mV.

Over a temperature from -40°C to 85°C, the reference voltage is within 8 mV of the nominal 600mV.

Key Features

  • 600 mV low voltage reference.
  • ±6 mV initial accuracy.
  • High PSRR: 45 dB at 300 kHz.
  • Better line regulation: 1 mV (VIN from 2.2 V to 18 V).
  • Low supply current: 90 µA.
  • Open drain output.
  • Directly drives optocouplers.
  • Industrial temperature range of -40ºC to 85ºC.
  • RoHS-compliant 5-lead TSOT23 package.
