H7211-30M5R from Shanghai Siproin Microelectronics, 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 | Voltage input pin; the datasheet specifies an operating input voltage range of 2.0 V to 6.0 V (absolute maximum -0.3 V to 7 V). |
| 2 | VSS | power_in | Ground pin; all datasheet voltages are referenced to this ground. |
| 3 | CE | input | Enable pin; a logic high of 1.5 V to VIN enables the regulator and a logic low of 0.3 V shuts it down, discharging COUT through the internal discharge path. |
| 4 | NC | unconnected | No connection; the datasheet pin table marks this pin as empty (空). |
| 5 | VOUT | power_out | Regulated voltage output; absolute maximum output pin voltage is VIN+0.3 V and output current is 600 mA absolute maximum (300 mA specified output current). |
