TPS71745QDRVRQ1

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

TPS71745QDRVRQ1 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 This pin is the regulated output voltage, and a minimum capacitance of 1 µF is required for stability from this pin to ground.
2 NR/FB passive On this fixed-voltage version the pin is NR, where an external capacitor bypasses noise generated by the internal band gap to lower output noise (FB, the feedback input, applies only to the adjustable version).
3 GND power_in Ground pin; the datasheet recommends connecting the input and output capacitor ground returns and the LDO ground pin as close to GND as possible.
4 EN input Driving EN above VEN(high) turns on the regulator, and driving it below VEN(low) puts the regulator into standby with the output disabled; the datasheet also says not to float the enable pin.
5 N/C unconnected Not connected internally; the pin can be tied to ground to improve thermal dissipation.
6 IN power_in Input to the device, with a 0.1-µF to 1-µF capacitor recommended for better performance; the device is designed to operate from 2.5 V to 6.5 V.
7 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
