# TLV713185PDBVT

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TLV713185PDBVT 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 | input | Input pin with an input voltage range of 1.4 V to 5.5 V; a small capacitor is recommended from this pin to ground. |
| 2 | GND | power_in | Ground pin; the thermal pad on the X2SON package is tied to this node, but the SOT-23 package has no separate thermal pad. |
| 3 | EN | input | Driving EN above 0.9 V turns on the regulator, and driving EN below 0.4 V puts the regulator into shutdown mode. |
| 4 | NC | unconnected | No internal connection. |
| 5 | OUT | output | Regulated output voltage pin; a small 1-μF ceramic capacitor is recommended from this pin to ground for best transient response. |
