# TPS73433DRVR

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

TPS73433DRVR 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 | Output of the regulator; a small capacitor (≥2.0µF ceramic) is needed to ground for stability. |
| 2 | NR | passive | For fixed voltage versions only, connecting an external capacitor to this pin bypasses noise generated by the internal bandgap, reducing output noise to very low levels. |
| 3 | GND | power_in | Ground. |
| 4 | EN | input | Enable input; driving high enables the regulator, driving low puts it in shutdown mode, and EN can be connected to IN if not used. |
| 5 | N/C | unconnected | Not internally connected; must be left open or tied to GND. |
| 6 | IN | power_in | Input supply. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
