# TPS7A1115PDRVR

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

TPS7A1115PDRVR from Texas Instruments, in a WSON-6(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 | power_out | Regulated output pin that requires a capacitor from OUT to ground for stability, with the recommended output capacitor range of 2.2 µF to 22 µF and ESR below 250 mΩ. |
| 2 | NC | unconnected | This pin is not internally connected and may be connected to ground for better thermal dissipation or left floating. |
| 3 | EN | input | Enable pin: logic high enables the device and logic low disables it, and connecting EN to IN is only acceptable if the IN pin voltage is greater than 0.9 V. |
| 4 | BIAS | input | Bias supply pin for low-input, low-output voltage operation, with a recommended bias capacitor of 0.1 µF from BIAS to ground and a bias voltage range of 1.7 V to 5.5 V. |
| 5 | GND | power_in | Ground pin that must be connected to ground. |
| 6 | IN | power_in | Primary input pin that requires a capacitor from IN to ground for stability, with an input voltage range of 0.75 V to 3.3 V and a recommended input capacitor of 2.2 µF. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
