Linear Regulator with PWRGD

5V Supply

Dropout Voltage

The LT

linear regulator. The device is capable of supplying 250mA

of output current with a dropout voltage of 400mV. De-

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

tems, the low quiescent current (65

µA operating) makes

the LT3013B an ideal choice. Quiescent current is also well

controlled in dropout.

Other features of the LT3013B include a PWRGD flag to

indicate output regulation. The delay between regulated

output level and flag indication is programmable with a

single capacitor. The LT3013B also has the ability to

operate with very small output capacitors. The regulator is

stable with only 3.3

µF on the output while most older

devices require between 10

µF and 100µF for stability.

Small ceramic capacitors can be used without any need for

series resistance (ESR) as is common with other regula-

tors. 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 LT3013B regulator is avail-

able in the thermally enhanced 16-lead TSSOP and the low

profile (0.75mm), 12 pin (4mm

× 3mm) DFN package,

both providing excellent thermal characteristics.
