GR6220B181MR-G

GR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

GR6220B181MR-G from GR, in a SOT-23-5. 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 VIN power_in Input pin for the regulator; the datasheet gives an input voltage range of 1.8 V to 7 V, with an absolute maximum Vin of 8 V.
2 VSS power_in Ground pin of the regulator.
3 CE input Enable pin: a level of 1.6 V to VIN enables the output and 0 to 0.5 V shuts it down, with shutdown current of 0.1 µA typical.
4 NC unconnected Not connected (marked 空, empty, in the datasheet).
5 VOUT power_out Regulated output pin; for this 1.8 V variant the nominal output is 1.8 V with ±2.5% tolerance, and the absolute maximum output current is 500 mA.
