H7211-12M5R from Shanghai Siproin Microelectronics, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Power Input Pin. Accepts 2.0V to 6.0V (absolute max -0.3V to 7V). Bypass with a low-ESR ceramic capacitor (typ. 10μF) to VSS. |
| 2 | VSS | power_in | Ground reference for the regulator. Connect to system ground. |
| 3 | CE | input | Chip Enable pin. CE=HIGH (VIH ≥ 1.5V up to VIN) enables the regulator; CE=LOW (VIL ≤ 0.3V) shuts down the LDO (shutdown current ≤0.1μA) and activates the internal 80Ω output-capacitor discharge shunt. Do not leave floating. |
| 4 | NC | unconnected | No Connection. Not internally bonded on the SOT23-5 package; may be left floating or tied to VSS for mechanical stability. |
| 5 | VOUT | power_out | Regulated output pin. Delivers up to 300mA at the factory-programmed output voltage (1.0V-5.0V, ±2% tolerance). Requires a low-ESR ceramic output capacitor (typ. 10μF) to VSS for stability. |
