TPS71730DCKR

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

TPS71730DCKR from Texas Instruments, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Input supply to the LDO, 2.5 V to 6.5 V. A 0.1 µF to 1 µF ceramic input capacitor is recommended for better performance.
2 GND power_in Device ground reference. All voltages are referenced to this pin.
3 EN input Enable input. Driving EN above VEN(high) turns on the regulator; driving it below VEN(low) puts the regulator into standby mode, disabling the output and reducing operating current. Range 0 V to VIN.
4 NR passive Noise-reduction pin (fixed-voltage version, TPS71730 is fixed 3.0 V). Connect an external capacitor from NR to GND to filter the internal band-gap noise and lower output noise. Absolute max 3.6 V.
5 OUT power_out Regulated 3.0 V output, 150 mA. Requires a minimum 1 µF ceramic capacitor from this pin to GND for stability.
