TPS71727DCKR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SC-70-5

TPS71727DCKR from Texas Instruments, in a SC-70-5. 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 IN power_in Input to the device; a 0.1-µF to 1-µF capacitor is recommended for better performance, and the input voltage range is 2.5 V to 6.5 V.
2 GND power_in Ground reference pin for the regulator.
3 EN input Driving EN above VEN(high) turns on the regulator, and driving it below VEN(low) puts the device into standby, disabling the output and reducing operating current; EN must not be left floating, and its voltage range is 0 V to VIN.
4 NR/FB passive On this fixed-voltage version it is the noise reduction pin, where a capacitor filters band-gap noise; the feedback (FB) function, a resistor divider from OUT that sets the output voltage, applies only to the adjustable version.
5 OUT power_out Regulated output voltage; a minimum of 1 µF capacitance is required for stability from this pin to ground, with output voltage range 0.9 V to 5 V for fixed versions.
