TPS71727DSER

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

TPS71727DSER 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	output	This pin is the regulated output voltage, and a minimum capacitance of 1 μF is required for stability from this pin to ground.
2	GND	power_in	Ground pin; ground return connections for the input and output capacitors and the LDO should be made as close to this pin as possible.
3	NR/FB	passive	On this fixed-voltage version the pin is the noise reduction (NR) capacitor connection, which filters internal band-gap noise to lower output noise; the feedback (FB) function applies only to the adjustable version.
4	EN	input	Driving EN above VEN(high) turns the regulator on and driving it below VEN(low) places it in standby; the pin must not be left floating, and its absolute maximum is VIN + 0.3 V or 7 V, whichever is greater.
5	N/C	unconnected	Not connected; this pin can be tied to ground to improve thermal dissipation.
6	IN	power_in	Input to the device, operating from 2.5 V to 6.5 V with a 7 V absolute maximum, and a 0.1-μF to 1-μF capacitor is recommended for better performance.
