ELECTRICAL CHARACTERISTICS
Over operating temperature range (TJ = â40°C to +125°C), VIN = VOUT(TYP) + 0.3V or 2.7V, whichever is greater; IOUT = 1mA,
VEN = VIN, COUT = 2.2µF, CNR = 0.01µF, unless otherwise noted. For TPS79901, VOUT = 3.0V.
Typical values are at TJ = +25°C.

(1) Minimum VIN = VOUT + VDO or 2.7V, whichever is greater.
(2) VDO is not measured for devices with VOUT(NOM) < 2.8V because minimum VIN = 2.7V.
