# GR6119C33M5G

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

GR6119C33M5G 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, with a supply range of 1.8V to 15V and an absolute maximum input voltage of 18V. |
| 2 | VSS | power_in | Ground terminal of the regulator, which is the reference for the output voltage limits (Vout range Vss-0.3V to Vin+0.3V). |
| 3 | CE | input | Enable pin that turns the output on or off: high above 0.3VIN up to VIN, low at 0V to 0.5V, and shutting the output off reduces the standby current to 0.1uA typical. |
| 4 | NC | unconnected | No internal connection on the SOT-23-5 package (marked as empty, 空, in the datasheet). |
| 5 | VOUT | power_out | Regulated output pin, selectable from 1.8V to 5.0V with ±2.5% output voltage accuracy and rated for at least 200mA when Vin=4.3V and Vout=3.3V. |
