# TPS72728DSER

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · WSON-6(1.5x1.5)

TPS72728DSER from Texas Instruments, in a WSON-6(1.5x1.5). 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 voltage pin with a required 1-μF ceramic capacitor to ground for stability. |
| 2 | NC | unconnected | No connection pin that can be tied to ground to improve thermal dissipation. |
| 3 | GND | power_in | Ground pin. |
| 4 | EN | input | Enable pin that turns on the regulator when driven above 0.9 V and enters shutdown mode when driven below 0.4 V, reducing operating current to 120 nA nominal. |
| 5 | NC | unconnected | No connection pin that can be tied to ground to improve thermal dissipation. |
| 6 | IN | input | Input pin requiring a small capacitor to ground for stability. |
