# TPS71733DRVR

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

TPS71733DRVR from Texas Instruments, in a WSON-6-EP(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 | OUT | output | The regulated output voltage pin; a minimum capacitance of 1 μF is required for stability from this pin to ground. |
| 2 | NR/FB | passive | On the fixed-voltage version (TPS71733) this pin is the noise reduction (NR) pin, where a noise reduction capacitor filters noise generated by the internal band gap to lower output noise. |
| 3 | GND | power_in | Ground pin; the datasheet recommends returning the input and output capacitor grounds and the device GND pin together as close to each other as possible. |
| 4 | EN | input | Driving EN above VEN(high) turns on the regulator, and driving it below VEN(low) puts the regulator into standby mode, disabling the output and reducing operating current; EN must not be left floating. |
| 5 | N/C | unconnected | Not connected; this pin can be tied to ground to improve thermal dissipation. |
| 6 | IN | input | Input to the device, which operates from 2.5 V to 6.5 V; a 0.1-μF to 1-μF capacitor is recommended for better performance. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
