CAT102TDI-GT3 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 range from -40°C to 85°C, the reference voltage is within 8.0 mV of the nominal 600 mV. In addition, the error amplifier output and the supply voltage pin (IN) are on separate pins.

Power supply rejection is a high 45 dB at 300 kHz. The output, OUT, can sink 20 mA at a maximum saturation voltage of 250 mV.

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.
