ELECTRICAL CHARACTERISTICS

Electrical Characteristics: VIN = VEN = VOUT + 1V; CIN = COUT = 1 µF for VOUT ≥ 2.5V, CIN = COUT = 2.2 µF for

VOUT < 2.5V; IOUT = 100 µA; TJ = +25°C, bold values indicate –40°C to +125°C, unless noted. Note 1

Note 1: Specification for packaged product only.

2: Regulation is measured at constant junction temperature using low duty cycle pulse testing.

3: 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 2.5V, dropout voltage is the input-to-out-

put differential with the minimum input voltage 2.5V.

4: Ground pin current is the regulator quiescent current. The total current drawn from the supply is the sum

of the load current plus the ground pin current.
