LM4040DIM3-2.5 Shunt Voltage Reference IC Features
The LM4040DIM3-2.5 is characterized by its low dynamic impedance, low noise, and low temperature coefficient, ensuring a stable output voltage across a broad spectrum of operating currents and temperatures. It operates without the need for external capacitors and is stable with all capacitive loads. The device also features a precision Zener diode and requires only a small quiescent current for regulation. It regulates the output voltage by shunting more or less current to ground, depending on the input voltage and load. The only external component needed is a resistor between the cathode and the input voltage to set the input current .
LM4040DIM3-2.5 Applications
The LM4040DIM3-2.5 is used in various applications due to its precision and reliability. It is ideal for space-critical applications and can be found in sub-miniature SC70 and SOT-23 surface-mount packages. Typical applications include shunt regulators, where it helps to maintain a stable reference voltage for analog-to-digital converters (ADCs) or digital-to-analog converters (DACs). It is also used in bounded amplifiers to reduce saturation-induced delays and protect succeeding stage damage. Additionally, it can be used to protect op-amp inputs by limiting the input voltage to the op-amp to a safe level .
