5V Supply

Dropout Voltage

The LT

linear regulator. The device is capable of supplying 20mA

of output current with a dropout voltage of 350mV. De-

signed for use in battery-powered or high voltage sys-

tems, the low quiescent current (7

µA operating) makes

the LT3014B an ideal choice. Quiescent current is also well

controlled in dropout.

Other features of the LT3014B include the ability to oper-

ate with very small output capacitors. The regulators are

stable with only 0.47

µF on the output while most older

devices require between 10

µF and 100µF for stability.

Small ceramic capacitors can be used without the neces-

sary addition of ESR as is common with other regulators.

Internal protection circuitry includes reverse-battery pro-

tection, current limiting, thermal limiting and reverse

current protection.

The device is available as an adjustable device with a 1.22V

reference voltage. The LT3014B regulator is available in

the 5-lead ThinSOT and 8-lead DFN packages.
