TPS71725DCKR from Texas Instruments, in a SC-70-5. 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 | IN | power_in | Input supply voltage; operating range 2.5 V to 6.5 V, absolute maximum -0.3 V to 7 V, with 0.1 μF to 1 μF input capacitor recommended for better performance. |
| 2 | GND | power_in | Ground reference. |
| 3 | EN | input | Enable control input; logic high above 1.2 V enables normal operation, logic low below 0.4 V disables regulator and reduces operating current. |
| 4 | NR | passive | Noise reduction pin for fixed-voltage versions; high-impedance connection for capacitor ≤0.01 μF to filter band-gap reference noise and improve PSRR. |
| 5 | OUT | output | Regulated output voltage with range 0.9 V to 5 V; minimum output load capacitance of 1 μF required for stability. |
