LM4130BIM5-2.5/NOPB

Voltage Reference Overview

The LM4130BIM5-2.5/NOPB is a precision micropower low dropout voltage reference manufactured by Texas Instruments, featuring a fixed output of 2.500V in an SOT-23-5 package. It provides high initial accuracy of ±0.2% and a temperature coefficient of 10 ppm/°C within the 0°C to +85°C range (20 ppm/°C over -40°C to +85°C). The device operates with a supply current of ≤75 μA and supports an output current up to 20 mA. It exhibits excellent line regulation (≤150 ppm/V) and load regulation (≤60 ppm/mA), with a typical dropout voltage of 275 mV at 10 mA.
