The device is capable of supplying 50m A output current with a dropout voltage of 300m V. Designed for use in battery-powered or high voltage systems, the low quiescent current (30µA operating and 1µA in shutdown) makes the LT3010 an ideal choice. Quiescent current is also well controlled in dropout. Other Features of the LT3010 include the ability to operate with very small output capacitors. The regulators are stable with only 1µF on the output while most older devices require between 10µF and 100µF for stability. Small ceramic capacitors can be used without the necessary addition of ESR as is mon with other regulators. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting and reverse current protection. The device is available in a fixed output voltage of 5V and as an adjustable device with a 1.275V reference voltage. The LT3010 regulator is available in the 8-lead MSOP package with an exposed pad for enhanced thermal handling capability.
