BL Shanghai Belling · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN1x1-4L
BL9161G-28BADRN from BL Shanghai Belling, in a DFN1x1-4L. 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 | VOUT | power_out | Output voltage of the LDO regulator, rated for up to 300mA output current. |
| 2 | GND | power_in | Ground pin; the datasheet asks for separate ground planes for VIN and VOUT, each connected only at the GND pin. |
| 3 | EN | input | Chip enable with an internal pull-down resistor; the LDO turns on when EN is above 1.2V and shuts down when EN falls below 0.4V, with an absolute maximum of -0.3V to VIN. |
| 4 | VIN | power_in | Power input voltage; operating range is 2.2V to 6V, with an absolute maximum of 6V. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
