(1)

When the device is connected to external feedback resistors at the FB pin, external resistor tolerances are not included.

(2)

VIN = 1.5 V for VOUT < 1.0 V.

(3)

VIN = 2 V for VOUT < 1.5 V.

6.5 Electrical Characteristics

at operating temperature range (TJ = –40°C to 125°C), VIN = VOUT(NOM) + 0.5 V or 1.5 V (whichever is greater), IOUT = 1 mA,

VEN = VIN, and CIN = COUT = 1 μF, unless otherwise noted. All typical values at TJ = 25°C.
