Frequently Asked Questions
How much dropout voltage does TPS79718DCKT have at full load?
The TPS79718DCKT has a typical dropout voltage of 330mV at the full 150mA rated output current, allowing operation from an input as low as 1.9V when driving a 1.8V rail — making it well-suited for single-cell Li-Ion battery-powered designs.
Can TPS79718DCKT power an ARM Cortex-M microcontroller core?
Yes. The TPS79718DCKT delivers a stable 1.8V fixed output at up to 150mA with very low noise (30µV RMS), making it an excellent choice for powering ARM Cortex-M core rails, DSPs, or low-voltage FPGA I/O banks that require clean 1.8V supply.
Does TPS79718DCKT support shutdown to save battery power?
Yes. The device includes a logic-level enable (EN) pin. When pulled low, the regulator enters shutdown mode with less than 1µA total input current, preserving battery life in portable or IoT devices during sleep cycles.
What is the power-good (PG) pin used for on TPS79718DCKT?
The open-drain power-good output goes high (requires external pull-up) once the output voltage reaches approximately 92% of its target. System designers use this flag to sequence multiple power rails or to hold a microcontroller in reset until supply is stable.
Which alternative LDOs are compatible with TPS79718DCKT footprint?
Pin-compatible or functionally similar alternatives include the TPS799xx family from TI (different fixed voltages), Diodes Inc. AP7313, Richtek RT9193, and Torex XC6221. Always verify output voltage, dropout spec, and enable logic polarity before swapping.
