Frequently Asked Questions
What is the quiescent current of the TPS797285DCKR?
The TPS797285DCKR features an ultra-low quiescent current, making it highly efficient in light-load and standby conditions. This characteristic is critical for battery-powered applications such as IoT sensors and wearables where idle power consumption directly impacts battery life.
What is the dropout voltage of the TPS797285DCKR at full load?
The TPS797285DCKR has a typical dropout voltage of 105mV and a maximum of 200mV at the full 50mA output current. This low dropout enables efficient operation even when the input voltage closely approaches the 2.85V regulated output, which is especially beneficial for single-cell lithium-ion battery applications near end-of-discharge.
What does the Power Good output on the TPS797285DCKR do?
The Power Good (PG) output is an open-drain signal that asserts high when the regulated output voltage is within the valid regulation window. It is commonly used to enable downstream ICs or microcontrollers only after the supply has stabilized, supporting safe power-sequencing in multi-rail system designs.
What package does the TPS797285DCKR come in, and what are alternative orderable options?
The TPS797285DCKR is packaged in a SOT-23 (5-Pin) package, which is a compact surface-mount form factor suitable for high-density PCB layouts. Texas Instruments offers the same device in other package variants depending on the application requirements; consult the TPS797285 datasheet for the full ordering information table.
What is the input voltage range supported by the TPS797285DCKR?
The TPS797285DCKR supports an input voltage range from 1.8V to 5.5V, with an absolute maximum rating of 6V. This wide range makes it compatible with single-cell Li-Ion batteries, USB power rails, and 3.3V logic supply inputs commonly found in portable consumer and industrial electronics.
