GR5300A28M3G

GR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

GR5300A28M3G from GR, in a SOT-23. 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 of the LDO regulator.
2 VOUT power_out Regulated output of the LDO; the 2.8 V variant (GR5300A28M3G) regulates to 2.8 V ±2.5% at IOUT = 1 mA with VIN = 5 V.
3 VIN power_in Input supply pin; maximum input voltage is 10 V in the product selection table and the absolute maximum rating is 12 V.
