Frequently Asked Questions
What is the minimum input voltage required to maintain a regulated 2.8 V output with TPS79928YZUR?
The TPS79928YZUR requires a minimum input voltage of 2.975 V to regulate its fixed 2.8 V output. With a nominal dropout voltage of 100 mV and a maximum dropout of 175 mV at full 200 mA load, the device keeps dropout losses low, making it suitable for single-cell Li-ion battery applications where the input rail hovers just above 3 V.
For a wearable fitness tracker running on a 3.3 V rail, can TPS79928YZUR supply the RF front-end at 2.8 V?
Yes. With a 3.3 V input and the 2.8 V fixed output, the input-to-output differential is 500 mV, well above the maximum 175 mV dropout at 200 mA. The device can continuously supply up to 200 mA to the RF front-end while the 5-pin DSBGA footprint occupies less than 1 mm² of PCB area, conserving the limited board space typical in wearables.
When should TPS79928YZUR be chosen over a switching regulator for a 2.8 V supply?
TPS79928YZUR is preferred when noise performance matters more than efficiency, such as powering analog front-ends or RF circuits that are sensitive to switching noise. Unlike a buck converter, the LDO produces no switching harmonics and avoids the need for bulky inductors. At load currents below 50 mA and with only a 500 mV input-output differential, efficiency loss is minimal and the 5-pin DSBGA solution is physically smaller than any switching regulator equivalent.
