描述 The LT®3011 is a high voltage, micropower, low dropout LT®3011 is a high voltage, micropower, low dropout voltage 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) quiescent current (46μA operating and 1μA shutdown)
is well controlled in dropout, making the LT3011 an ideal dropout
choice.

The LT3011 includes a PWRGD flag to indicate output The LT3011 includes a PWRGD flag to indicate output
regulation. The delay between regulated output level and delay
flag indication is programmable with a single capacitor.
The LT3011 also has the ability to operate with very small LT3011还具有非常小的经营能力
output capacitors; it is stable with only 1μF on the output. output capacitor; With only 1μF output, it is stable.
Small ceramic capacitors can be used without the addition of small ceramic capacitors
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 LT3011 has a 1.24V adjustable output
Reference voltage. The device is available in the thermally heat provided by the device
enhanced 12-lead MSOP and the low profi le (0.75mm)
10-pin (3mm × 3mm) DFN package, both providing excellent thermal characteristics. DFN package, 10-pin (3mm×3mm) while providing superior thermal characteristics.
