TPS78330DDCR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Input supply pin, 2.2 V to 5.5 V. Requires a small (typ. 1.0 µF, minimum 0.1 µF) ceramic bypass capacitor to ground placed close to the pin; tie the input and output capacitor grounds together at the IC ground with minimal impedance. |
| 2 | GND | power_in | Device ground. Both GND pins (2 and 4) must be tied to the system ground for proper operation. |
| 3 | EN | input | CMOS-compatible enable input. Drive above 1.2 V (V_EN(HI)) to enable the regulator; drive below 0.4 V (V_EN(LO)) to place the device in shutdown, reducing supply current to ~18 nA typical. Do not leave floating. |
| 4 | GND | power_in | Device ground. Both GND pins (2 and 4) must be tied to the system ground for proper operation. |
| 5 | OUT | power_out | Regulated 3.0-V output pin, 150 mA max. Requires a 1-µF or greater ceramic capacitor from OUT to GND for stable operation; typical dropout is 130 mV at 150 mA (25 °C). |
