5.6 Electrical Characteristics (continued)

Over operating temperature range (TJ = –40°C to 125°C), VIN = VOUT(nom) + 0.5V(1) , IOUT = 10mA, VEN = 1.7V, and COUT =

0.1μF (unless otherwise noted). Typical values are at TJ = 25°C

(1)

Minimum VIN = VOUT + VDO or 1.7V, whichever is greater.

(2)

TPS73201 is tested at VOUT = 2.5V.

(3)

Tolerance of external resistors not included in this specification.

(4)

VDO is not measured for output versions with VOUT(nom) < 1.8V, because minimum VIN = 1.7V.

(5)

Fixed-voltage versions only; refer to Application Information section for more information.
