GR6220B251MR-G

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

GR6220B251MR-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 voltage pin; the datasheet gives an input range of 1.8 V to 7 V, with an absolute maximum input voltage of 8 V.
2 VSS power_in Ground pin for the regulator.
3 CE input Chip enable pin: the output is enabled when VCE is at least 1.6 V and disabled when VCE is at most 0.5 V, with an input current of up to 0.5 µA.
4 NC unconnected No connection.
5 VOUT power_out Regulated output pin; for this 2.5 V part the output is ±2.5% and the maximum output current is 300 mA at VIN = 4.3 V, with absolute maximum output voltage of Vss-0.3 V to Vin+0.3 V.
