LM4040 Voltage Reference 2.048V SOT23-3 (4 Pack)

The LM4040 voltage reference IC is an accurate, temperature-compensated voltage source that provides 2.048V output. Ideal for space critical applications, the LM4040 comes in SOT-23 surface-mount package. The minimum operating current ranges from 60uA to 25mA and its temperature coefficient is 20 ppm per degree.

LM4040-AIM3-SOT23-3-003

The LM4040 device is effectively a precision Zener diode. The part requires a small quiescent current for regulation, and regulates the output voltage by shunting more or less current to ground, depending on input voltage and load. The only external component requirement is a resistor between the cathode and the input voltage to set the input current. An external capacitor can be used on the input or output, but is not required.
