CAT102

Precision, Adjustable Shunt Regulator

(600mV Reference)

FEATURES

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 (IN) are on separate pins.

600mv low voltage reference

35ppm low temperature coefficient

±6mV initial accuracy

High PSRR: 45dB at 300kHz

Better line regulation: 1mV (V_INfrom 2.2V to 18V)

Low supply current: 90µA

Power supply rejection is a high 45dB at 300kHz. The

output, OUT, can sink 20mA at a maximum saturation

voltage of 250mV.

Open drain output

Directly drives optocouplers

Industrial temperature range of -40ºC to 85ºC

RoHS-compliant 5-lead TSOT23 package

When combined with an optocoupler, the CAT102 can

be used as an error amplifier that controls the

feedback loop in isolated low-output voltage switching

power supplies.

APPLICATION
