What are the key features of REG113NA-2.5/250?

400 mA output current with only 0.25 V nominal dropout enables 2.5 V regulation from a near-discharged Li-ion cell at 2.9 V minimum input
±1.5% output voltage accuracy over temperature ensures precise 2.5 V rail for reference circuits, ADCs, and mixed-signal systems
Wide 1.8 V to 10 V input range in compact SOT-23-5 package suits post-regulation from 3.3 V, 5 V, or 9 V system rails

What is REG113NA-2.5/250 used for?

REG113NA-2.5/250 provides a stable 2.5 V reference supply for precision ADC rails, sensor excitation, and DAC reference inputs in industrial instrumentation and embedded systems. Its 400 mA output capacity and wide input range from 1.8 V to 10 V make it suitable for portable medical devices, wireless sensor nodes, and test equipment requiring a clean 2.5 V regulated output from varying supply conditions.

Frequently Asked Questions

What is the dropout voltage of REG113NA-2.5/250 and how does it affect operation near a Li-ion battery's minimum voltage?

REG113NA-2.5/250 has a nominal dropout voltage of 0.25 V and a maximum of 0.41 V at 400 mA. With a minimum input of 2.9 V specified, it maintains a regulated 2.5 V output even as a Li-ion cell discharges toward 3.0 V, extending useful battery runtime compared to regulators requiring 0.5 V or more of headroom.

How accurate is the 2.5 V output of REG113NA-2.5/250 when used as a precision ADC reference supply?

REG113NA-2.5/250 guarantees a 2.5 V output accuracy of ±1.5% over temperature and load conditions. For a 12-bit ADC with a 2.5 V reference rail, this equates to a worst-case reference error of approximately 37.5 mV, which may require a dedicated voltage reference for 12-bit or higher accuracy needs but is sufficient for 8-bit to 10-bit ADC applications.

Is REG113NA-2.5/250 suitable for post-regulating a 5 V bus down to 2.5 V in an industrial sensor module?

Yes, REG113NA-2.5/250 accepts inputs up to 10 V and provides 400 mA at 2.5 V, making it directly compatible with a 5 V industrial bus. The 2.5 V dropout across 400 mA on a 5 V input produces approximately 1 W of dissipation, which the SOT-23-5 package can handle with a small copper pour, enabling clean analog supply isolation from the noisy 5 V digital rail.
