# TPS70918DRVR

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

TPS70918DRVR 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 | power_out | Regulated output voltage; connect a small 2.2-µF or greater ceramic capacitor from this pin to ground to assure stability. |
| 2 | NC | unconnected | No internal connection. |
| 3 | GND | power_in | Ground reference for the device; the thermal pad is electrically connected to this GND node. |
| 4 | EN | input | Enable pin: drive high to enable the device and low to put it into low-current shutdown; it may be left floating to enable the device, and the maximum voltage must remain below 6.5 V. |
| 5 | NC | unconnected | No internal connection. |
| 6 | IN | power_in | Unregulated input to the device, which accepts 2.7 V to 30 V per the Recommended Operating Conditions. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
