SLVS351I â SEPTEMBER 2002 â REVISED MAY 2006
ELECTRICAL CHARACTERISTICS
over recommended operating temperature range (TJ = â40°C to +125°C), VEN = VIN,, VIN = VOUT(nom) + 1 V(1), IOUT = 1mA,
COUT = 10µF, and CNR = 0.01µF, unless otherwise noted. Typical values are at +25°C.

(1) Minimum VIN = VOUT + VDO or 2.7V, whichever is greater. TPS79650 is tested at VIN = 5.5V.
(2) Tolerance of external resistors not included in this specification.
(3) VDO is not measured for TPS79618 and TPS79625 because minimum VIN = 2.7V.
(4) For adjustable version, this applies only after VIN is applied; then VEN transitions high to low.
