LM4140 Datasheet (National Semiconductor) - High Precision Low Noise Low Dropout Voltage

LM4140, High Precision Low Noise Low Dropout Voltage

The LM4140 series of precision references are designed to combine high accuracy, low drift and noise with low power dissipation in a small package.

The LM4140 is the industry’s first reference with output voltage options lower than the bandgap voltage.

The key to the advance performance of the LM414
