Texas Instruments LM4040-N
the LM4040-N eliminates the need for an external stabilizing capacitor while maintaining stability with any capacitive load, thus making the LM4040-N easy to use. The minimum operating current increases from 60μA for the 2.5V LM4040-N to 100μA for the 10V LM4040-N. The LM4040-N uses a fuse and Zener-zap reverse breakdown voltage trim during wafer sort to make sure that the prime parts have an accuracy of better than ±0.1% (A grade) at 25°C.| Part No. | LM4040-N |
