# TPS7A3501DRVT

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · WSON-6(2x2)

TPS7A3501DRVT from Texas Instruments, in a WSON-6(2x2). 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; a capacitor of at least 10 µF (X5R/X7R recommended) must be tied from this pin to ground to assure stability, with absolute maximum of 7 V and recommended range of 1.71 V to 5 V. |
| 2 | EN | input | Enable pin; driving EN high turns on the device and driving it low turns it off, it must not be left floating and can be connected to IN if not used. |
| 3 | GND | power_in | Ground. |
| 4 | NR | passive | Noise-reduction pin; a capacitor of at least 10 nF to GND is required for stability (1 µF recommended to minimize noise), and a resistor to GND or IN programs the input-to-output voltage. |
| 5 | SENSE | input | Control-loop error amplifier input that must be connected to OUT, ideally at the point of load to maximize accuracy. |
| 6 | OUT | power_out | Regulator output; a capacitor of at least 10 µF (X5R/X7R recommended) must be tied from this pin to ground to assure stability, with output current up to 1 A. |
| 7 | PowerPAD | passive | Exposed thermal pad; connect to the ground plane for improved thermal performance. |
