5 / 25 page  TPS799-Q1 www.ti.com SBVS097F – MARCH 2008 – REVISED JUNE 2015 6.5 Electrical Characteristics over operating temperature range (TJ = –40°C to 125°C), VIN = VOUT(TYP) + 0.3 V or 2.7 V, whichever is greater; IOUT = 1 mA, VEN = VIN, COUT = 2.2 μF, CNR = 0.01 μF (unless otherwise noted) For TPS79901, VOUT = 3 V. Typical values are at TJ = 25°C.
