of a device may be impaired.

characterization and correlation with statistical process controls. The
LT3020I is guaranteed over the full –40°C to 125°C operating junction
temperature range.
Note 3: This IC includes overtemperature protection that is intended to
protect the device during momentary overload conditions. Junction
temperature will exceed 125°C when overtemperature protection is active.
Continuous operation above the specified maximum operating junction
temperature may impair device reliability.
Note 4: Maximum junction temperature limits operating conditions. The
regulated output voltage specification does not apply for all possible
combinations of input voltage and output current. Limit the output current
range if operating at maximum input voltage. Limit the input voltage range
if operating at maximum output current.
Note 5: Typically the LT3020 supplies 100mA output current with a 1V
input supply. The guaranteed minimum input voltage for 100mA output
current is 1.10V.
Note 6: The LT3020 is tested and specified for these conditions with an
external resistor divider (20k and 30.1k) setting V
resistor divider adds 10µA of output load current. The line regulation and
load regulation specifications refer to the change in the 0.2V reference
voltage, not the 0.5V output voltage. Specifications for fixed output voltage
devices are referred to the output voltage.

Note 7: Dropout voltage is the minimum input to output voltage differential
needed to maintain regulation at a specified output current. In dropout the
output voltage equals: (V
Note 8: GND pin current is tested with V
source load. The device is tested while operating in its dropout region.
This condition forces the worst-case GND pin current. GND pin current
decreases at higher input voltages.
Note 9: Adjust pin bias current flows out of the ADJ pin.
Note 10: Shutdown pin current flows into the SHDN pin.
Note 11: Reverse output current is tested with IN grounded and OUT
forced to the rated output voltage. This current flows into the OUT pin and
out of the GND pin. For fixed voltage devices this includes the current in
the output resistor divider.
Note 12: The LT3020 is tested and specified for these conditions with an
external resistor divider (20k and 100k) setting V
resistor divider adds 10µA of load current.

Note 14: Minimum input voltage is the minimum voltage required by the
control circuit to regulate the output voltage and supply the full 100mA
rated current. This specification is tested at V
