MAX8863T/S/R, Low-Dropout, 120mA Linear Regulators MAX8864T/S/R
Electrical Characteristics (continued)
(VIN = +3.6V, VGND = 0V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Note 2)

THERMAL PROTECTION
Thermal Shutdown Temperature TSHDN 170 °C Thermal Shutdown Hysteresis ∆TSHDN 20 °C
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.
Typical Operating Characteristics
(VIN = +3.6V, CIN = 1μF, COUT = 1μF, TA = +25°C, MAX886_T, unless otherwise noted.)
