The LT®3011 is a high voltage, micropower, low dropoutlinear regulator. The device is capable of supplying 50mA ofoutput current with a dropout voltage of 300mV. Designedfor use in battery-powered high voltage systems, the lowquiescent current (46μA operaTIng and 1μA in shutdown)is well controlled in dropout, making the LT3011 an idealchoice.The LT3011 includes a PWRGD fl ag to indicate outputregulaTIon. The delay between regulated output level andfl ag indicaTIon is programmable with a single capacitor.The LT3011 also has the ability to operate with very smalloutput capacitors; it is stable with only 1μF on the output.Small ceramic capacitors can be used without the addiTIonof any series resistance (ESR) as is common with otherregulators. Internal protection circuitry includes reversebatteryprotection, current limiting, thermal limiting, andreverse current protection.The LT3011 features an adjustable output with a 1.24Vreference voltage. The device is available in the thermallyenhanced 12-lead MSOP and the low profi le (0.75mm)10-pin (3mm × 3mm) DFN package, both providing excellentthermal characteristics.
