TDSEMIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
78L05L from TDSEMIC, 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 | VOUT | power_out | Regulated 5V output (4.9V min, 5.0V typ, 5.15V max at VIN=10V, Io=40mA) supplying up to 100mA. |
| 2 | GND | power_in | Ground reference for the regulator, common to input and output. |
| 3 | VIN | power_in | Supply input with 7-35V operating range and absolute maximum of -0.3 to 35V (Vout<10V). |
