# BL8568CB5ATR25

**BL Shanghai Belling** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

BL8568CB5ATR25 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. Operating range 2.0V to 6.0V (absolute max 8V). A 1uF ceramic input capacitor to Vss is recommended close to the pin. |
| 2 | Vss | power_in | Ground reference pin for the regulator. Connect to the system ground plane; the internal 1.5kohm discharge resistor sinks Vout to this pin when CE is low. |
| 3 | CE | input | Chip enable, active high. Drive >=1.5V (up to Vin) to enable the regulator; drive <=0.25V (or leave floating; internal 5Mohm pull-down to Vss) to shut down. In shutdown quiescent current drops to ~0.1uA and Vout is discharged through the internal 1.5kohm resistor. |
| 4 | NC | unconnected | No internal connection. May be left floating or tied to Vss for mechanical stability. |
| 5 | Vout | power_out | Regulated output voltage (2.5V for the '25' suffix), accurate to +/-2%, capable of 500mA continuous output current. A 1uF ceramic output capacitor to Vss is required for stability; discharged through an internal 1.5kohm resistor when CE is low. |
