BL9165-120BARN
BL Shanghai Belling · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
BL9165-120BARN from BL Shanghai Belling, 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 | Power input voltage; the datasheet specifies an input range of 1.8V to 5.5V, with absolute maximum VIN of -0.3V to +6V. |
| 2 | GND | power_in | Ground; the layout guidance recommends connecting the separate VIN and VOUT ground planes only at this GND pin. |
| 3 | EN | input | Chip enable with an internal pull-down resistor; EN must be above 1.2V to turn the LDO on and below 0.4V to enter shutdown, and it may be tied to VIN for continuous operation. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated output voltage; the output capacitor (1.0 µF X7R recommended) should be located not more than 0.5 inch from this pin. |
