BL9165-180BARN

BL(Shanghai Belling) · Linear Voltage Regulators (LDO) · SOT-23-5

BL9165-180BARN 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, with an operating range of 1.8V to 5.5V and absolute maximum of -0.3V to +6V.
2 GND power_in Ground; the datasheet says the VIN and VOUT ground planes should connect only at this pin.
3 EN input Chip enable: the LDO turns on when EN is above 1.2V and shuts down when EN is below 0.4V; the pin has an internal pull-down resistor and may be tied to VIN for continuous operation.
4 NC unconnected No connection.
5 VOUT power_out Regulated output voltage; the output capacitor should be placed no more than 0.5 inch from this pin.
