Applications
The TPS75501KC is designed for point-of-load regulation in portable electronics, embedded processor boards, and battery-powered devices requiring stable voltage with minimal dropout. Its adjustable output and 2.8V to 5.5V input range make it a strong fit for powering DSPs, FPGAs, and microcontrollers in handheld instruments and IoT gateways. Engineers designing RF front-ends and mixed-signal systems also benefit from its tight line regulation of 0.1%/V, which reduces noise coupling into sensitive analog circuits.

Frequently Asked Questions
What is the dropout voltage of the TPS75501KC and why does it matter for battery-powered designs?
The TPS75501KC has a typical dropout voltage of 0.25V, meaning the input rail needs to be only 0.25V above the target output. This low dropout extends usable battery life in single-cell Li-ion systems operating between 2.8V and 5.5V, allowing regulation to continue even as the battery discharges near its end-of-life voltage.
How does the TPS75501KC's adjustable output differ from fixed-voltage LDO alternatives?
Unlike fixed-output LDOs, the TPS75501KC allows designers to set any desired output voltage using an external resistor divider, covering a wide range within the 2.8V to 5.5V input window. This flexibility reduces SKU count, as one part can serve multiple voltage rails such as 1.8V, 2.5V, or 3.3V outputs across different board revisions.
Which processor and FPGA power supply applications suit the TPS75501KC?
With 0.1%/V line regulation and a fast transient response, the TPS75501KC is well suited for powering microcontrollers, DSPs, and low-power FPGAs that demand tight supply tolerances. Systems such as industrial sensor nodes, wireless modules, and portable test equipment benefit from its stable output across load step events common in digital processing workloads.
