5.6 Electrical Characteristics

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)

For VOUT(nom) < 1.6V, when VIN ≤ 1.6V, the output locks to VIN and may result in a damaging over-voltage condition on the output. To

avoid this situation, disable the device before powering down VIN. (Legacy silicon only)

(3)

TPS73601 is tested at VOUT = 2.5V.

(4)

Tolerance of external resistors not included in this specification.

(5)

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

(6)

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