H7210-28M5R

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

H7210-28M5R 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. Recommended supply range 2.5V to 5.5V (absolute max 8V). Requires a 10uF ceramic input capacitor (CIN) placed close to the pin between VIN and GND for stable operation.
2 GND power_in Device ground reference. Return path for the input and output capacitors; keep low-impedance wiring between VIN and GND.
3 CE input Chip Enable pin. CMOS hysteresis inverter input that shuts down the regulator when driven low; drive with VIN (enable) or VSS (disable). When CE is low, an internal pull-down resistor discharges VOUT (fast discharge on -33M5R variants).
4 NC unconnected No connection. Leave floating or optionally tie to GND for mechanical stability.
5 VOUT power_out Regulated output pin. Fixed 2.8V (±2%) for the -28 option, up to 500mA capable (Vin-Vout=1V). Requires ≥10uF low-ESR ceramic output capacitor (CL) placed close to VOUT and GND for stable phase compensation.
