TPS71730DCKR from Texas Instruments, in a SC-70-5. 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 to the LDO, 2.5 V to 6.5 V. A 0.1 µF to 1 µF ceramic input capacitor is recommended for better performance. |
| 2 | GND | power_in | Device ground reference. All voltages are referenced to this pin. |
| 3 | EN | input | Enable input. Driving EN above VEN(high) turns on the regulator; driving it below VEN(low) puts the regulator into standby mode, disabling the output and reducing operating current. Range 0 V to VIN. |
| 4 | NR | passive | Noise-reduction pin (fixed-voltage version, TPS71730 is fixed 3.0 V). Connect an external capacitor from NR to GND to filter the internal band-gap noise and lower output noise. Absolute max 3.6 V. |
| 5 | OUT | power_out | Regulated 3.0 V output, 150 mA. Requires a minimum 1 µF ceramic capacitor from this pin to GND for stability. |
