Linear Technology LT3012BEFE#PBF

Description
The LT3012B is a high voltage, micropower low dropout linear regulator. It can supply 250mA of output current with a dropout voltage of 400mV. Designed for use in battery-powered or high voltage systems, the low quiescent current (40µA operating) makes the LT3012B an ideal choice. Quiescent current is also well-controlled in dropout.
Other features of the LT3012B include the ability to operate with very small output capacitors. The regulators are stable with only 3.3uF on the output while most older devices require between 10uF and 100uF 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 LT3012B regulator is available in the 16-lead TSSOP and 12-pin low profile (0.75mm) (4mm x 3mm) DFN packages with an exposed pad for enhanced thermal handling capability.
