# TLV75518PDYDR

**Texas Instruments** · Others · SOT-23-5

TLV75518PDYDR from Texas Instruments, in a SOT-23-5. 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 | IN | power_in | Input pin; a capacitor of 1µF or larger is required from this pin to ground. |
| 2 | GND | power_in | Ground pin, internally connected to the exposed thermal pad. |
| 3 | EN | input | Enable pin: drive EN greater than VHI to turn on the regulator and less than VLO to place the LDO into shutdown mode. |
| 4 | NC | unconnected | No internal connection. |
| 5 | OUT | power_out | Regulated output voltage pin; a capacitor of 1µF or larger is required from this pin to ground. |
