# TLV1117IDCYR

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-4

TLV1117IDCYR from Texas Instruments, in a SOT-223-4. 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 | ADJ | input | Adjustment pin establishing 1.25V reference voltage between VOUT and ADJ for external resistor network output voltage setting. |
| 2 | VOUT | power_out | Regulated output pin providing 1.25V to 13.8V adjustable output at up to 800mA output current. |
| 3 | VIN | power_in | Input voltage pin accepting 2.7V to 15V supply for the linear regulator. |
| 4 | VOUT | power_out | Regulated output pin connected internally to pin 2 for increased output current capability. |
