LM4040AIM3-3.0/NOPB TI Precision Micropower Shunt Voltage Reference | SOT-23-3 | 3.0V, ±0.1%

Product Overview

The LM4040AIM3-3.0/NOPB is a precision micropower shunt voltage reference from Texas Instruments (TI), offering a fixed 3.0V output with excellent accuracy and stability. Housed in a compact SOT-23-3 package, this device is ideal for space-constrained applications requiring a stable voltage reference. With a low operating current of 60 µA (typical) and a wide current range from 60 µA to 15 mA, it provides flexibility for various low-power designs. The LM4040 series is known for its low temperature coefficient (100 ppm/°C maximum) and high output accuracy (±0.1% for the A-grade), making it suitable for precision analog circuits.
