FUNCTIONAL DIAGRAM
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.
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.
