BL79L05

GME(银河微电) · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

BL79L05 from GME(银河微电), in a SOT-89. 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 GND power_in Ground reference pin (labelled G on the SOT-89 drawing), common to the input and output capacitors.
2 IN power_in Negative input voltage pin (labelled I), absolute maximum -35 V, with a 0.33 µF input capacitor recommended.
3 OUT power_out Regulated negative output (labelled O), -5.0 V typical (-4.8 to -5.2 V) for BL79L05, with a 0.1 µF output capacitor recommended.
