78L06-300

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

78L06-300 from UMW, 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 OUT power_out Regulated output of the 78L06, with a typical 6 V output (5.91 V min to 6.09 V max at TJ=25°C, VI=11 V, IO=10 mA) and a peak output current rating of 0.3 A.
2 GND power_in Ground pin of the three-terminal regulator, serving as the common return for input and output.
3 IN power_in Unregulated input to the regulator; the absolute maximum input voltage is 35 V for output voltages from 5 V to 18 V, which includes the 6 V version.
