GR7533

GR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

GR7533 from GR, in a SOT-89-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Chip ground terminal; SOT89-3 pin 1 per the GR75xx pin table (TO-92 pin 1 is also GND).
2 VIN power_in Input supply pin (labelled as the startup input terminal); the datasheet limits VIN to 18 V in the electrical characteristics and 20 V maximum input voltage in the absolute maximum ratings.
3 VOUT power_out Regulated output pin; for GR7533 the output voltage is 3.3 V typical (3.201 V to 3.399 V, ±3%) at IOUT = 1 mA, with output current of at least 60 mA (100 mA typical) stated in the datasheet.
