Low-Dropout, 120mA Linear Regulators

__________________________________________Typical Operating Characteristics

(VIN = +3.6V, CIN = 1µF, COUT = 1µF, TA = +25°C, MAX886_T, unless otherwise noted.)

ELECTRICAL CHARACTERISTICS (continued)

(VIN = +3.6V, VGND = 0V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Note 2)

Note 2: Limits are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed through cor-

relation using Statistical Quality Control (SQC) Methods.

Note 3: Guaranteed by line regulation test.

Note 4: Adjustable mode only.

Note 5: Not tested. For design purposes, the current limit should be considered 120mA minimum to 420mA maximum.

Note 6: The dropout voltage is defined as (VIN - VOUT) when VOUT is 100mV below the value of VOUT for VIN = VOUT +2V.
