# TPS73701DRVR

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

TPS73701DRVR 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 | Regulated output voltage; minimum 1.0μF output capacitor required for stability. |
| 2 | FB | input | Feedback input to error amplifier for output voltage setting; adjustable version TPS73701 only. |
| 3 | GND | power_in | Ground reference; connected to exposed pad for thermal dissipation. |
| 4 | EN | input | Enable input; logic high (≥1.7V) enables regulator, low (≤0.5V) disables to shutdown mode; must not float. |
| 5 | NC | unconnected | No connection; not used internally. |
| 6 | IN | power_in | Unregulated input power supply; operating range 2.2V to 5.5V. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
