TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89
TP78L33T3 from TECH PUBLIC, 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 | VO | power_out | Regulated 3.3 V output (3.168 V min, 3.432 V max at Tj=25°C), with a 0.1 µF output capacitor shown in the application circuit; maximum output current is 100 mA. |
| 2 | GND | power_in | Ground reference for the regulator, common to input and output capacitors in the application circuit. |
| 3 | VI | power_in | Unregulated input voltage, absolute maximum 30 V, with a 0.33 µF input capacitor shown in the application circuit. |
