4 / 23 page LM4140 SNVS053E – JUNE 2000 – REVISED APRIL 2013 www.ti.com LM4140 Electrical Charateristics (continued) Unless otherwise specified, VIN = 3.0V for the LM4140-1.024 and LM4140-1.250, VIN = 5.0V for all other voltage options, VEN = VIN. COUT = 1μF (1), I LOAD = 1mA, TA = TJ = 25°C. Limits with standard typeface are for TA = 25°C, and limits in boldface type apply over 0°C to 70°C temperature range.

(6) Dropout voltage is defined as the minimum input to output differential voltage at which the output voltage drops by 0.5% below the value measured with VIN = 3.0V for the LM4140-1.024 and LM4140-1.250, VIN = 5.0V for all other voltage options. (7) The output noise is based on 1.024V option. Output noise is linearly proportional to VREF. 4 Submit Documentation Feedback Copyright © 2000–2013, Texas Instruments Incorporated Product Folder Links: LM4140 |
