6 / 28 page  TPS793 SLVS348L – JULY 2001 – REVISED MAY 2015 www.ti.com 6.5 Electrical Characteristics Over recommended operating temperature range TJ = –40°C to 125°C, VEN = VIN, VIN = VOUT(nom) + 1 V (1), I OUT = 1 mA, COUT = 10 μF, CNR = 0.01 μF (unless otherwise noted). Typical values are at TJ = 25°C.

(2) Dropout is not measured for the TPS79318 and TPS79325 because minimum VIN = 2.7 V. (3) For adjustable versions, this parameter applies only after VIN is applied; then VEN transitions high to low. 6 Submit Documentation Feedback Copyright © 2001–2015, Texas Instruments Incorporated Product Folder Links: TPS793 |
