5 / 33 page TPS795 www.ti.com SLVS350I – OCTOBER 2002 – REVISED MAY 2015 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 25°C.

(2) Tolerance of external resistors not included in this specification. (3) Dropout is not measured for the TPS79501 and TPS79525 because minimum VIN = 2.7 V. (4) For adjustable version, this applies only after VIN is applied; then VEN transitions high to low.
