250mA, 4V to 80V

Low Dropout Micropower

Linear Regulator with PWRGD

FEATURES

DESCRIPTIO

The LT^®3013B is a high voltage, micropower low dropout

linearregulator.Thedeviceiscapableofsupplying250mA

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 (65µA operating) makes

theLT3013Banidealchoice.Quiescentcurrentisalsowell

controlled in dropout.

■

Wide Input Voltage Range: 4V to 80V

■

Low Quiescent Current: 65µA

■

Low Dropout Voltage: 400mV

■

Output Current: 250mA

■

No Protection Diodes Needed

■

Adjustable Output from 1.24V to 60V

■

Stable with 3.3µF Output Capacitor

■

Stable with Aluminum, Tantalum or Ceramic

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 3.3µF on the output while most older

devices require between 10µF and 100µF for stability.

Smallceramiccapacitorscanbeusedwithoutanyneedfor

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.
