UA78L09ACPKE6

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

UA78L09ACPKE6 from Texas Instruments, in a SOT-89-3. 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 OUTPUT output Regulated output pin; the datasheet recommends a 0.1 µF output capacitor placed as close as possible to the OUTPUT and COMMON pins, and the device supplies up to 100 mA output current.
2 COMMON power_in Ground reference pin; all voltages are specified with respect to GND.
3 INPUT input Unregulated input pin; for UA78L05AC the recommended input voltage is 7 V to 20 V, with a recommended 0.33 µF input capacitor placed as close as possible to the INPUT and GND pins.
