TPS73225DBVR 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. Recommended operating range 1.7 V to 5.5 V (absolute max 6 V). Provides power to the NMOS pass element and internal circuitry. |
| 2 | GND | power_in | Device ground reference. |
| 3 | EN | input | Enable input. Driving EN high turns on the regulator; driving it low puts the device into shutdown mode (IQ < 1 µA). May be tied to IN if unused. Absolute max 6 V. |
| 4 | NR/FB | passive | Noise-reduction pin for this fixed-voltage (2.5 V) version. Connecting an external capacitor (typically 0.1 µF) from this pin to GND bypasses the internal bandgap noise, reducing output noise to ~30 µVRMS (10 kHz to 100 kHz). Absolute max 6 V. |
| 5 | OUT | power_out | Regulated 2.5-V output, up to 250 mA. Stable with any value or type of output capacitor, including no capacitor. Absolute max 5.5 V. |
