L78L05ABUTR-HXY

HXY MOSFET · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

L78L05ABUTR-HXY from HXY MOSFET, 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 VOUT power_out Output voltage pin of the regulator, which delivers up to 150mA of output current.
2 GND power_in Ground pin; the datasheet requires a common ground between the input and output voltages.
3 VIN power_in Input voltage pin; the input must remain typically 2.0 V above the output voltage, even at the low point of the input ripple.
