# TPS72727DSER

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

TPS72727DSER 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 | power_out | Regulated output voltage pin. A small 1-μF ceramic capacitor is needed from this pin to ground to assure stability. |
| 2 | NC | unconnected | No connection. This pin can be tied to ground to improve thermal dissipation. |
| 3 | GND | power_in | Ground pin. |
| 4 | EN | input | Driving EN over 0.9 V turns on the regulator, and driving EN below 0.4 V puts the regulator into shutdown mode, reducing the operating current to 120 nA, nominal. |
| 5 | NC | unconnected | No connection. This pin can be tied to ground to improve thermal dissipation. |
| 6 | IN | power_in | Input pin. A small capacitor is needed from this pin to ground to assure stability. |
