Typical Application
Description
The LT3011 is a high voltage, micropower, low dropout linear regulator.The device is capable of supplying 50mA output current with a dropout voltage of 300mV.Designed for use in battery-powered high voltage systems,the low quiescent current (46μA operating and 1μA in shutdown)is well controlled in dropout,making the LT3011 an ideal choice.The LT3011 includes a PWRGD flag to indicate output regulation.The delay between regulated output level and flag indication is programmable with a single capacitor.The LT3011 also has the ability to operate with very small output capacitors;it is stable with only 1μF on the output.Small ceramic capacitors can be used without the addition of any 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 LT3011 features an adjustable output with a 1.24V reference voltage.The device is available in the thermally enhanced 12-lead MSOP and the low profile (0.75mm) 10-pin (3mm × 3mm) DFN package, both providing excellent thermal characteristics.
