BL8563-18PRA from BL Shanghai Belling, 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 | Supply voltage input, 2.0 V to 6.0 V (8 V abs max). Bypass with 1 uF ceramic to Vss close to the pin. |
| 2 | Vss | power_in | Ground / negative supply return for the regulator and reference. |
| 3 | CE | input | Chip enable. Drive high (Vceh >= 1.5 V, up to Vin) to enable the regulator; drive low (Vcel <= 0.25 V) to shut down (Istandby = 0.1 uA typ). When CE is low a 1.5 kΩ discharge resistor is switched across Vout. Internal ~500 kΩ pull-down to Vss. |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to Vss. |
| 5 | Vout | power_out | Regulated output, 1.8 V (±2%) for the -18 option, 300 mA max output current. Bypass with 1 uF ceramic to Vss for stability. Discharged through internal 1.5 kΩ when CE is low. |
