TPS7A9101DSKR from Texas Instruments, in a SON-10-EP(2.5x2.5). 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 | OUT | output | Regulated output with maximum voltage VIN + 0.3V; requires ≥10µF capacitor to GND for stability. |
| 2 | OUT | output | Regulated output with maximum voltage VIN + 0.3V; requires ≥10µF capacitor to GND for stability. |
| 3 | FB | input | Feedback input (maximum 3.6V) serving as control loop error amplifier input to set device output voltage. |
| 4 | GND | power_in | Device ground connected to thermal pad. |
| 5 | PG | tri_state | Open-drain power good indicator output (maximum 7.0V, 5mA sink current) requiring 10kΩ to 100kΩ external pullup resistor. |
| 6 | SS_CTRL | input | Soft start control input (0 to VIN + 0.3V) connected to GND or IN to change NR/SS capacitor charging current; must connect to GND if capacitor not used to avoid output overshoot. |
| 7 | EN | input | Enable input (0 to 7.0V) enabling regulator when VEN ≥ VIH(EN) and disabling when VEN ≤ VIL(EN); must connect to IN if enable function not used. |
| 8 | NR/SS | input | Noise reduction input (0 to 3.6V) for external capacitor connection to filter internal bandgap noise and set output ramp rate to limit inrush current. |
| 9 | IN | power_in | Input power supply (operating range 1.4V to 6.5V, maximum 7.0V) requiring ≥10µF ceramic input capacitor. |
| 10 | IN | power_in | Input power supply (operating range 1.4V to 6.5V, maximum 7.0V) requiring ≥10µF ceramic input capacitor. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
