The CAT102 is a precision, adjustable shunt regulator. It provides a 600mV reference voltage with low line and power supply voltage return characteristics. The device is suitable for use in the control loop of low voltage switching power supplies.
The CAT102 is a precision, adjustable shunt regulator featuring a 600 mV reference voltage, low supply current (300 µA), and high power‑supply rejection (45 dB at 300 kHz). It is supplied in a 5‑lead SOT‑23 package and operates over an industrial temperature range of –40 °C to 85 °C.
Typical applications include SMPS control loops, low‑temperature‑coefficient voltage references, power‑management circuits, and isolated DC‑DC converters where the device can directly drive optocouplers. The datasheet provides pin descriptions, absolute maximum ratings, electrical characteristics, and example application circuits.
