H7211-12M5R

Shanghai Siproin Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

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.
