Electrical Characteristics
Unless otherwise specified: V
appearing in standard typeface are for T
range for operation, −40˚C to +125˚C. (Note 6) (Note 7)
Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device
is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the Electrical
Characteristics tables.
Note 2: All voltages are with respect to the potential at the GND pin.
Note 3: The Absolute Maximum power dissipation depends on the ambient temperature and can be calculated using the formula:
where T
Absolute Maximum Ratings for the SOT23-5 package results from substituting the Absolute Maximum junction temperature, 150˚C, for T
for θ
Absolute Maximum power dissipation can be increased by 4.5mW for each degree below 70˚C, and it must be derated by 4.5mW for each degree above 70˚C. Same
principle applies to the micro SMD package.
Note 4: The human body model is 100pF discharged through 1.5kΩ resistor into each pin. The machine model is a 200 pF capacitor discharged directly into each
pin.
Note 5: Like the Absolute Maximum power dissipation, the maximum power dissipation for operation depends on the ambient temperature. The 250mW rating
appearing under Operating Ratings for the SOT23-5 package results from substituting the maximum junction temperature for operation, 125˚C, for T
and 220˚C/W for θ
temperatures above 70˚C. The maximum power dissipation for operation can be increased by 4.5mW for each degree below 70˚C, and it must be derated by 4.5mW
for each degree above 70˚C. Same principle applies to the micro SMD package.
Note 6: All limits are guaranteed. All electrical characteristics having room-temperature limits are tested during production with T
Statistical Quality Control (SQC) methods. All hot and cold limits are guaranteed by correlating the electrical characteristics to process and temperature variations
and applying statistical process control.
Note 7: The target output voltage, which is labeled V
Note 8: An increase in the load current results in a slight decrease in the output voltage and vice versa.
Note 9: Dropout voltage is the input-to-output voltage difference at which the output voltage is 100mV below its nominal value.
Note 10: Short circuit current is measured on input supply line after pulling down V
Note 11: Guaranteed by design. The capacitor tolerance should be
temperature, DC bias and even capacitor case size for the capacitor in the application should be considered during device selection to ensure this minimum
capacitance specification is met. X7R capacitor types are recommended to meet the full device temperature range.
Note 12: Turn-on time is time measured between the enable input just exceeding V
Note 13: 100V machine model for Power-good flag, pin 4.
Note 14: The low and high thresholds are generated together. Typically a 2.6% difference is seen between these thresholds.
Note 15: The minimum V
