The device supplies 100mA of output current with a typical dropout voltage of 250mV. A single external capacitor provides programmable low noise reference performance and output soft-start functionality. The LT3061’s quiescent current is merely 45μA and provides fast transient response with a minimum 3.3μF output capacitor. In shutdown, quiescent current is less than 3μA and the reference soft start capacitor is reset. The LT3061 features an NMOS pull-down that discharges the output when SHDN or IN is driven low. Internal protection circuitry includes reverse-battery protection, reverse-current protection, current limit with foldback and thermal shutdown. The LT3061 is available in fixed output voltages of 3.3V and 5V, and as an adjustable device with an output voltage range from the 600mV reference up to 19V. The LT3061 is offered in the thermally enhanced 8-lead 2mm × 3mm DFN and MSOP packages.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: Absolute maximum input to output differential voltage is not achievable with all combinations of rated IN pin and OUT pin voltages. With the IN pin at 50V, the OUT pin may not be pulled below 0V. The total measured voltage from IN to OUT must not exceed ±50V. Note 3: The LT3061 is tested and specified under pulse load conditions such that TJ ≅ TA. The LT3061E regulators are 100% tested at TA = 25°C and performance is guaranteed from 0°C to 125°C. Performance at –40°C to 125°C is assured by design, characterization and correlation with statistical process controls. The LT3061I regulators are guaranteed over the full –40°C to 125°C operating junction temperature range. The LT3061MP regulators are 100% tested over the –55°C to 150°C operating junction temperature. The LT3061H regulators are 100% tested at the 150°C operating junction temperature. High junction temperatures degrade operating lifetimes. Operating lifetime is derated at junction temperature greater than 125°C. Note 4: The LT3061 adjustable version is tested and specified for these conditions with the ADJ connected to the OUT pin. Note 5: 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 the maximum input voltage. Limit the input-to-output voltage differential if operating at maximum output current. Current limit foldback limits the maximum output current as a function of input-tooutput voltage.
