TPS7A4701QRGWRQ1 from Texas Instruments, in a VQFN-20-EP(5x5). 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 | OUT | power_out | Regulator output pin; requires a capacitor ≥10 µF to ground for stability, with 47-µF ceramic capacitor highly recommended. |
| 2 | NC | unconnected | No connect pin; can be left open or tied to any voltage between GND and IN. |
| 3 | SENSE/FB | input | Control-loop error amplifier input; serves as SENSE pin in ANY-OUT mode (connect to OUT) or FB pin in adjustable mode with external resistors. |
| 4 | 6P4V2 | input | Program pin for ANY-OUT mode; when connected to GND, adds 6.4 V to nominal output voltage; only GND connection allowed. |
| 5 | 6P4V1 | input | Program pin for ANY-OUT mode; when connected to GND, adds 6.4 V to nominal output voltage; only GND connection allowed. |
| 6 | 3P2V | input | Program pin for ANY-OUT mode; when connected to GND, adds 3.2 V to nominal output voltage; only GND connection allowed. |
| 7 | GND | power_in | Ground connection. |
| 8 | 1P6V | input | Program pin for ANY-OUT mode; when connected to GND, adds 1.6 V to nominal output voltage; only GND connection allowed. |
| 9 | 0P8V | input | Program pin for ANY-OUT mode; when connected to GND, adds 0.8 V to nominal output voltage; only GND connection allowed. |
| 10 | 0P4V | input | Program pin for ANY-OUT mode; when connected to GND, adds 0.4 V to nominal output voltage; only GND connection allowed. |
| 11 | 0P2V | input | Program pin for ANY-OUT mode; when connected to GND, adds 0.2 V to nominal output voltage; only GND connection allowed. |
| 12 | 0P1V | input | Program pin for ANY-OUT mode; when connected to GND, adds 0.1 V to nominal output voltage; only GND connection allowed. |
| 13 | EN | input | Enable pin; device is enabled when voltage on this pin exceeds VEN(HI), can be tied to IN if independent enable control is not required. |
| 14 | NR | passive | Noise-reduction pin; requires capacitor ≥10 nF to GND for stability, 1-µF recommended to maximize ac performance and minimize output noise. |
| 15 | IN | power_in | Input supply pin; requires capacitor ≥1 µF to ground for stability, 10-µF recommended to reduce PCB layout sensitivity. |
| 16 | IN | power_in | Input supply pin; requires capacitor ≥1 µF to ground for stability, 10-µF recommended to reduce PCB layout sensitivity. |
| 17 | NC | unconnected | No connect pin; can be left open or tied to any voltage between GND and IN. |
| 18 | NC | unconnected | No connect pin; can be left open or tied to any voltage between GND and IN. |
| 19 | NC | unconnected | No connect pin; can be left open or tied to any voltage between GND and IN. |
| 20 | OUT | power_out | Regulator output pin; requires a capacitor ≥10 µF to ground for stability, with 47-µF ceramic capacitor highly recommended. |
| 21 | PowerPAD | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
