BL Shanghai Belling · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3
BL9161G-30BPRT from BL Shanghai Belling, in a SOT-23-3. 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 | GND | power_in | Device ground return. Connect to system ground plane. |
| 2 | VOUT | power_out | Regulated 3.0V output (±2%). Requires a ≥1µF ceramic bypass capacitor for stability; supplies up to 300mA with 205mV dropout at full load. |
| 3 | VIN | power_in | Power input voltage, 2.2V to 6V (absolute max +6V). Should be bypassed with a ≥1µF ceramic capacitor to ground. |
