TLV7103318QDSERQ1

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · WSON-6(1.5x1.5)

TLV7103318QDSERQ1 from Texas Instruments, in a WSON-6(1.5x1.5). 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 EN1 input Enable pin for regulator 1: driving EN1 over 0.9 V turns on regulator 1, and driving it below 0.4 V puts regulator 1 into shutdown mode.
2 IN power_in Input pin: a small capacitor is needed from this pin to ground to assure stability.
3 EN2 input Enable pin for regulator 2: driving EN2 over 0.9 V turns on regulator 2, and driving it below 0.4 V puts regulator 2 into shutdown mode.
4 GND power_in Ground pin.
5 OUT2 power_out Regulated output voltage pin for channel 2: a small 1 µF ceramic capacitor is needed from this pin to ground to assure stability.
6 OUT1 power_out Regulated output voltage pin for channel 1: a small 1 µF ceramic capacitor is needed from this pin to ground to assure stability.
