LM4040D50QDBZR TI Voltage Reference | SOT-23-3 | 5V, 0.5%

Product Overview

The LM4040D50QDBZR from Texas Instruments is a precision micropower shunt voltage reference offering a fixed 5V output with an initial accuracy of ±0.5%. Housed in a compact SOT-23-3 package, it is designed for space-constrained applications requiring a stable and accurate reference voltage. With a low operating current of 60 µA (typical) and a wide current range from 60 µA to 15 mA, it is ideal for battery-powered and portable devices.
