# TPS7A1118PDRVR

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

TPS7A1118PDRVR 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 pin that requires a ceramic capacitor to ground for stability. |
| 2 | NC | unconnected | No internal connection; may be connected to ground for thermal dissipation or left floating. |
| 3 | EN | input | Enable pin; logic high enables the device and logic low disables the device. |
| 4 | BIAS | input | BIAS pin that enables low-input voltage, low-output voltage (LILO) conditions and requires a ceramic capacitor to ground. |
| 5 | GND | power_in | Ground pin; must be connected to ground. |
| 6 | IN | input | Input pin that requires a ceramic capacitor to ground for stability. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
