Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS

Note 1: Limits are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed through
correlation using Statistical Quality Control (SQC) Methods.
Note 2: The dropout voltage is defined as VIN - VOUT, when VOUT is 100mV below the value of VOUT for VIN = VOUT + 0.5V.
Note 3: Time needed for VOUT to reach 95% of final value.
