L78L09ABUTR-HXY
HXY MOSFET · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89
L78L09ABUTR-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 | Regulated output voltage pin, with the device delivering up to 150mA of output current and protected by internal current limiting and thermal shutdown. |
| 2 | GND | power_in | Ground pin, and a common ground is required between the input and output voltages. |
| 3 | VIN | power_in | Unregulated input voltage pin, which the datasheet characterizes for VIN = 7V to 18V and which must remain typically 2.0 V above the output voltage. |
