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. In addition, the error amplifier output and the supply voltage pin (IN) are on separate pins.

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

APPLICATION
■ SMPS control loop
