5 / 42 page TPS717 www.ti.com SBVS068H – FEBRUARY 2006 – REVISED JANUARY 2015 6.5 Electrical Characteristics Over operating temperature range (TJ = –40°C to 125°C), VIN = VOUT(nom) + 0.5 V or 2.5 V, whichever is greater; IOUT = 0.5 mA, VEN = VIN, COUT = 1.0 μF, CNR = 0.01 μF, unless otherwise noted. For TPS71701, VOUT = 2.8 V. Typical values are at TJ = 25°C.

(2) Does not include external resistor tolerances. (3) VDO is not measured for devices with VOUT(nom) < 2.6 V because the minimum VINis 2.5 V. (4) Maximum VEN(high) = VIN + 0.3 or 6.5 V, whichever is smaller. Copyright © 2006–2015, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Links: TPS717 |
