Frequently Asked Questions
What is the minimum input voltage needed to maintain 2.8 V regulated output from the REG101NA-2.8/250G4?
With a typical dropout voltage of 60 mV and maximum dropout of 130 mV at 100 mA load, the REG101NA-2.8/250G4 requires a minimum input voltage of approximately 2.86 V to maintain its 2.8 V regulated output. This low dropout makes it suitable for single-cell Li-ion battery powered designs where the battery voltage approaches 3 V near depletion.
How does the REG101NA-2.8/250G4 suit RF module and camera sensor power supply designs?
The REG101NA-2.8/250G4 provides a fixed 2.8 V output with ±1.5% accuracy, which matches the common 2.8 V power rail used by CMOS image sensors, Bluetooth RF modules, and GPS receivers. Its low dropout of 60 mV and 100 mA capacity deliver clean, regulated power in a 5-pin SOT-23 footprint that integrates easily alongside the sensitive analog components it supplies.
What is the output voltage accuracy and current capability of the REG101NA-2.8/250G4?
The REG101NA-2.8/250G4 delivers a fixed 2.8 V output with ±1.5% accuracy, meaning the output stays between approximately 2.758 V and 2.842 V across load and temperature. The 100 mA maximum output current is sufficient for low-power sensors and RF front-end modules typically consuming 50 mA to 80 mA in active mode.
For what input voltage range is the REG101NA-2.8/250G4 rated and is it RoHS-compliant?
The REG101NA-2.8/250G4 operates with input voltage from 2.86 V to 10 V, with an absolute maximum of 12 V, covering 3.3 V, 5 V, and unregulated 9 V adapter inputs. The part carries Pbfree Code Yes (JESD-609 e4), confirming full RoHS lead-free compliance for use in consumer electronics and industrial equipment sold in regulated markets.
