6.5 Electrical Characteristics

Over operating temperature range (–40°C ≤ TJ, TA ≤ 125°C), VIN = VOUTnom + 0.5 V or 2.7 V (whichever is greater), IOUT = 1 mA, VEN = VIN, COUT = 2.2 μF, and CNR = 0.01 μF, unless otherwise noted.
For the adjustable version (TPS73501-Q1), VOUT = 3 V. Typical values are at TA = 25°C.

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