SBVS037I–AUGUST 2003–REVISED MAY 2006
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) TPS73201 is tested at VOUT = 2.5V.
(3) VDO is not measured for the TPS73214, TPS73215 or TPS73216 since minimum VIN = 1.7V.
(4) Fixed-voltage versions only; refer to Applications section for more information.
