Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Regulator output requiring minimum capacitor 10µF connected between pin and ground with 47µF ceramic recommended close to device. |
| 2 | NC | unconnected | No-connect pin that can be left floating or connected to any voltage between GND and IN. |
| 3 | SENSE/FB | input | Error amplifier input (TPS7A4701 only) serving as SENSE pin in ANY-OUT mode (must connect to OUT) or FB pin in adjustable mode; connect to load point to maximize accuracy. |
| 4 | 6P4V2 | input | ANY-OUT programming input that adds 6.4V to 1.4V base voltage when connected to GND; must not connect any voltage other than GND; leave floating if unused. |
| 5 | 6P4V1 | input | ANY-OUT programming input that adds 6.4V to 1.4V base voltage when connected to GND; must not connect any voltage other than GND; leave floating if unused. |
| 6 | 3P2V | input | ANY-OUT programming input that adds 3.2V to 1.4V base voltage when connected to GND; must not connect any voltage other than GND; leave floating if unused. |
| 7 | GND | power_in | Ground reference connection for power and signal circuits. |
| 8 | 1P6V | input | ANY-OUT programming input that adds 1.6V to 1.4V base voltage when connected to GND; must not connect any voltage other than GND; leave floating if unused. |
| 9 | 0P8V | input | ANY-OUT programming input that adds 0.8V to 1.4V base voltage when connected to GND; must not connect any voltage other than GND; leave floating if unused. |
| 10 | 0P4V | input | ANY-OUT programming input that adds 0.4V to 1.4V base voltage when connected to GND; must not connect any voltage other than GND; leave floating if unused. |
| 11 | 0P2V | input | ANY-OUT programming input that adds 0.2V to 1.4V base voltage when connected to GND; must not connect any voltage other than GND; leave floating if unused. |
| 12 | 0P1V | input | ANY-OUT programming input that adds 0.1V to 1.4V base voltage when connected to GND; must not connect any voltage other than GND; leave floating if unused. |
| 13 | EN | input | Enable input that activates device when voltage exceeds VEN(HI) maximum enable voltage; connect to IN if enable function not required. |
| 14 | NR | passive | Noise reduction pin requiring minimum capacitor 10nF connected between pin and ground for stability with 1µF ceramic recommended for best AC performance. |
| 15 | IN | power_in | Input power supply pin requiring minimum capacitor 1µF connected between pin and ground with 10µF ceramic recommended close to device for stability. |
| 16 | IN | power_in | Input power supply pin requiring minimum capacitor 1µF connected between pin and ground with 10µF ceramic recommended close to device for stability. |
| 17 | NC | unconnected | No-connect pin that can be left floating or connected to any voltage between GND and IN. |
| 18 | NC | unconnected | No-connect pin that can be left floating or connected to any voltage between GND and IN. |
| 19 | NC | unconnected | No-connect pin that can be left floating or connected to any voltage between GND and IN. |
| 20 | OUT | output | Regulator output requiring minimum capacitor 10µF connected between pin and ground with 47µF ceramic recommended close to device. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
