TPS71745DSER

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

TPS71745DSER 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 OUT power_out Regulated output voltage; a minimum of 1 µF capacitance from this pin to ground is required for stability.
2 GND power_in Ground pin; per the layout guidance, the VIN and VOUT ground planes should connect only at this pin and the bypass capacitor ground should connect directly to it.
3 NR passive Fixed-voltage versions only; the noise reduction capacitor filters band-gap noise to lower output noise (an optional 0.01 µF ceramic is shown in the typical application).
4 EN input Driving EN above VEN(high) turns the regulator on and driving it below VEN(low) puts it in standby; VEN must stay within 0 V to VIN, its absolute maximum is VIN + 0.3 V or 7 V (whichever is greater), and the pin must not be left floating.
5 N/C unconnected Not connected internally; this pin can be tied to ground to improve thermal dissipation.
6 IN power_in Input supply to the device, operating from 2.5 V to 6.5 V, with a 0.1 µF to 1 µF capacitor recommended for better performance.
