LT3013

250mA, 4V to 80V

Low Dropout Micropower

Linear Regulator with PWRGD

FEATURES

DESCRIPTION

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

linearregulator. Thedeviceiscapableofsupplying250mA

ofoutputcurrentwithadropoutvoltageof400mV.Designed

foruseinbattery-poweredorhighvoltagesystems,thelow

quiescent current (65μA operating and 1μA in shutdown)

makes the LT3013 an ideal choice. Quiescent current is

also well 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

■

1μA Quiescent Current in Shutdown

■

Stable with 3.3μF Output Capacitor

Other features of the LT3013 include a PWRGD ﬂag to

indicate output regulation. The delay between regulated

output level and ﬂag indication is programmable with a

singlecapacitor. TheLT3013alsohastheabilitytooperate

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. Small ce-

ramic 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.

■

Stable with Aluminum, Tantalum or Ceramic

Capacitors

Reverse-Battery Protection

■

No Reverse Current Flow from Output to Input

■

Thermal Limiting

■

Thermally Enhanced 16-Lead TSSOP and

12-Pin (4mm × 3mm) DFN Package

APPLICATIONS

■

Low Current High Voltage Regulators

■

Regulator for Battery-Powered Systems

■

The device is available with an adjustable output with a

1.24Vreferencevoltage.TheLT3013regulator isavailable

in the thermally enhanced 16-lead TSSOP and the low

proﬁle (0.75mm), 12-pin (4mm × 3mm) DFN package,

both providing excellent thermal characteristics.
