CAT102 Precision, Adjustable Shunt Regulator (600 mV Reference) FEATURES DESCRIPTION
600 mV low voltage reference
The CAT102 is a low-voltage reference and amplifier. Designed for the control loop of low-voltage power
±6 mV initial accuracy
supplies, the reference voltage has been designed for
High PSRR: 45 dB at 300 kHz
600 mV. Over a temperature from -40°C to 85°C, the
Better line regulation: 1 mV (V
reference voltage is within 8 mV of the nominal
IN from 2.2 V to 18 V)
600mV. In addition, the error amplifier output and the
Low supply current: 90 µA
supply voltage pin (IN) are on separate pins.
Open drain output
Directly drives optocouplers
Power supply rejection is a high 45 dB at 300 kHz. The output, OUT, can sink 20 mA at a maximum
Industrial temperature range of -40ºC to 85ºC
saturation voltage of 250 mV.
RoHS-compliant 5-lead TSOT23 package
When combined with an optocoupler, the CAT102 can
APPLICATION
be used as an error amplifier that controls the feedback loop in isolated low-output voltage switching
