Frequently Asked Questions
What is the dropout voltage of the REG101NA-A/250?
The REG101NA-A/250 has a typical dropout voltage of 60 mV and a maximum of 130 mV at 100 mA output current. This extremely low dropout allows the regulator to maintain output regulation even when the input supply is only slightly above the output voltage, maximizing efficiency in battery-powered and low-headroom power architectures.
Is the REG101NA-A/250 adjustable or fixed output?
The REG101NA-A/250 supports both adjustable and fixed output configurations across the range of 2.5 V to 5.5 V. In fixed output configurations, no external resistors are needed; in adjustable mode, a resistor divider sets the output voltage. This flexibility allows the same device to be used across multiple voltage rail requirements.
What makes the REG101NA-A/250 suitable for RF and analog applications?
The device is designed for low output noise, which is critical when supplying RF oscillators, LNAs, precision ADCs, and analog signal conditioning circuits where supply noise directly couples into the signal path. Its fast transient response also prevents output voltage droop when load current changes rapidly, maintaining clean supply rails for sensitive analog loads.
What package does the REG101NA-A/250 come in?
It is available in a 5-pin SOT-23 surface-mount package (JESD-30 code R-PDSO-G5), a compact footprint widely used for LDO regulators in portable electronics. The SOT-23 package is compatible with standard pick-and-place assembly and is available in tape-and-reel format for volume manufacturing, with RoHS compliant lead-free terminal finish.
