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 600mV. Over a junction temperature from -40°C to 105°C the reference voltage is within 8mV of the nominal 600mV. In addition, the error amplifier output and the supply voltage pin are on separate pins.

FEATURES
■ Low voltage reference: 600mV
■ Low temperature coefficient reference: 25ppm
■ Accurate 600mV reference voltage: +6mV at TJ=25°C
■ High PSRR: 45dB at 300kHz
■ High line rejection: +1mV (VCC from 2.2V to 18V)
■ Low supply current: 300µA
■ Open collector output
■ Directly drives optocouplers
■ Compact 5-lead SOT23 package
■ Industrial temperature range: -40°C to 85°C

APPLICATIONS
■ SMPS control loop
■ Low temperature coefficient voltage reference
■ Power management
■ Replaces zener diodes
