(1)

Specified by design

(2)

VIN = 2.0 V for VOUT ≤ 1.5 V.

(3)

Load Regulation is normalized to the output voltage at IOUT = 1 mA.

(4)

Dropout is measured by ramping VIN down until VOUT = VOUT(nom) x 95%, with IOUT = 200 mA.

6.5 Electrical Characteristics

Specified at TJ = –40°C to +125°C, VIN = VOUT(nom) + 0.5 V or 2.0 V (whichever is greater), IOUT = 1 mA, VEN = VIN, and CIN =

COUT = 1 µF (unless otherwise noted). Typical values are at TJ = 25°C.
