LT3013 250mA, 4V to 80V Low Dropout Micropower linear Regulator with PWRGD
The LT3013 is a high voltage, micropower low dropout linear regulator. The device is capable of supplying 250mA of output current with a dropout voltage of 400mV. Designed for use in battery-powered or high voltage systems, the low quiescent current (65µA operating and 1µA in shutdown) makes the LT3013 an ideal choice. Quiescent current is also well controlled in dropout.
Other features of the LT3013 include a PWRGD flag to indicate output regulation. The delay between regulated output level and flag indication is programmable with a single capacitor. The LT3013 also has the ability to operate with very small output capacitors. The regulator is stable with only 3.3µF on the output while most older devices require between 10µF and 100µF for stability. Small ceramic capacitors can be used without any need for series resistance (ESR) as is common with other regulators. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting and reverse current protection.
The device is available with an adjustable output with a 1.24V reference voltage. The LT3013 regulator is available in the thermally enhanced 16-lead TSSOP and the low profile (0.75mm), 12 pin (4mm × 3mm) DFN package, both providing excellent thermal characteristics
