BL9198-18BAPURN from BL(Shanghai Belling), in a SC-70-5. 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, operating range 2V to 6V (absolute maximum -0.3V to +6V). |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | Chip enable, active high with internal 8 MΩ pull-down for the A option (this MPN); logic high above 1.2V turns the output on and logic low below 0.4V shuts it down. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated output voltage (1.8V for this part), 300mA maximum output current, with 1µF minimum output capacitor (2.2µF or more recommended for the 1.8V version). |
