ELECTRICAL CHARACTERISTICS (CONTINUED)

Electrical Characteristics: TA = +25°C with VIN = VOUT + 1V; bold values indicate –40°C < TJ < +125°C;

IOUT = 10 mA; COUT = 10 µF ceramic, unless noted. Note 1

Conditions

Note 1: Specification for packaged product only.

2: VR is the nominal regulator output voltage when the input voltage is VIN = VOUT + 1V or VIN = 1.65V

(whichever is greater).

3: Minimum input for line regulation test is set to VOUT + 1V relative to the highest output voltage.

4: Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below

its nominal value measured at 1V differential. For outputs below 1.65V, dropout voltage is considered the

input-to-output voltage differential with the minimum input voltage of 1.65V. Minimum input operating volt-

age is 1.65V.
