DESCRIPTION

The LT®3013 is a high voltage, micropower low dropout
linear regulator. The device is capable of supplying 250mA
of output current with a dropout voltage of 400mV. Designed
for use in battery-powered or high voltage systems, the low
quiescent current (65μA operating and 1μA in shutdown)
makes the LT3013 an ideal choice. Quiescent current is
also well controlled in dropout.

Other features of the LT3013 include a PWRGD fl ag to
indicate output regulation. The delay between regulated
output level and fl ag indication is programmable with a
single capacitor. The LT3013 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. 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 LT3013 regulator is available
in the thermally enhanced 16-lead TSSOP and the low
profi le (0.75mm), 12-pin (4mm × 3mm) DFN package,
both providing excellent thermal characteristics.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.

Note 2: The LT3013 is tested and specifi ed for these conditions with the
ADJ pin connected to the OUT pin.

Note 3: Operating conditions are limited by maximum junction
temperature. The regulated output voltage specifi cation will not apply
for all possible combinations of input voltage and output current. When
operating at maximum input voltage, the output current range must be
limited. When operating at maximum output current, the input voltage
range must be limited.

Note 4: To satisfy requirements for minimum input voltage, the LT3013 is
tested and specifi ed for these conditions with an external resistor divider
(249k bottom, 649k top) for an output voltage of 4.5V. The external
resistor divider will add a 5μA DC load on the output.

Note 5: Dropout voltage is the minimum input to output voltage differential
needed to maintain regulation at a specifi ed output current. In dropout, the
output voltage will be equal to (V

Note 6: GND pin current is tested with V
load. This means the device is tested while operating close to its dropout
region. This is the worst-case GND pin current. The GND pin current will
decrease slightly at higher input voltages.

Note 7: ADJ pin bias current fl ows into the ADJ pin.

⎯S⎯H⎯D⎯

Note 8:

N pin current fl ows out of the ⎯S⎯H⎯D⎯N pin.

Note 9: Reverse output current is tested with the IN pin grounded and the
OUT pin forced to the rated output voltage. This current fl ows into the OUT
pin and out the GND pin.

Note 10: The LT3013E is guaranteed to meet performance specifi cations
from 0°C to 125°C operating junction temperature. Specifi cations over
the –40°C to 125°C operating junction temperature range are assured by
design, characterization and correlation with statistical process controls.

The LT3013H is tested to the LT3013H Electrical Characteristics table at
140°C operating junction temperature. High junction temperatures degrade
operating lifetimes. Operating lifetime is derated at junction temperatures
greater than 125°C.
