LM4040QBIM3-2.5/NOPB TI Voltage Reference | SOT-23-3 | 2.5V, ±0.1%

Product Overview

The LM4040QBIM3-2.5/NOPB is a precision micropower shunt voltage reference from Texas Instruments, offering a fixed 2.5V output with high accuracy and low temperature drift. Housed in a compact SOT-23-3 package, it is ideal for space-constrained applications requiring a stable reference voltage. With a typical output impedance of 0.5Ω and low dynamic impedance, it ensures excellent line and load regulation. The device operates over a wide current range from 60μA to 15mA, making it suitable for low-power and battery-powered systems. Its automotive qualification (AEC-Q100) enables use in harsh environments.
