LM4040CIM3-2.0/NOPB TI Voltage Reference

The LM4040C is a precision micropower shunt voltage reference providing a fixed 2.048 V output with 0.5% initial tolerance (C grade) . It operates over a 45-µA to 15-mA current range and features 20-ppm/°C typical temperature coefficient, with low dynamic impedance of 0.3 Ω . The device requires no external capacitor and is stable with all capacitive loads, simplifying design. The 3-pin SOT-23 package is optimized for space-constrained applications. Commercial temperature range is 0°C to 70°C. Selection is ideal for low-power battery-operated and portable applications requiring a stable fixed reference voltage. Applications include 8- to 12-bit ADC and DAC references, battery-powered instrumentation, portable medical devices, power supply monitoring, and adjustable current sources.
