Frequently Asked Questions
What is the input voltage range supported by TPS79601KTTRG3?
The TPS79601KTTRG3 accepts input voltages from 2.7V to 5.5V, making it compatible with single-cell Li-ion batteries, 3.3V rails, and 5V system supplies commonly found in portable and embedded designs.
How does TPS79601KTTRG3 perform in RF power supply designs requiring low noise?
The TPS79601KTTRG3 delivers high PSRR performance specifically optimized for RF applications, suppressing power supply noise by up to 60 dB at 1 MHz. This keeps sensitive RF front-end circuits operating cleanly, even when the input rail carries switching regulator ripple at frequencies above 100 kHz.
What maximum output current does TPS79601KTTRG3 support, and what is its dropout voltage at that load?
TPS79601KTTRG3 supports up to 1A continuous output current. At this full load, the typical dropout voltage is only 0.22V, with a maximum of 0.365V, allowing efficient regulation even when the input-output differential is small.
When would TPS79601KTTRG3 be preferred over a fixed-output LDO for a new design?
Because TPS79601KTTRG3 features an adjustable output, it allows a single part to cover multiple target voltages using external resistors, reducing BOM complexity across product variants. Its enable pin also supports sequencing, which is valuable in multi-rail 3.3V or 1.8V power-up schemes found in embedded systems.
