DESCRIPTION
20mA, 3V to 80V
Low Dropout Micropower
Linear Regulator
The LT
®
3014 is a high voltage, micropower low dropout
linear regulator. The device is capable of supplying 20mA of
output current with a dropout voltage of 350mV. Designed
for use in battery-powered or high voltage systems, the low
quiescent current (7μA operating and 1μA in shutdown)
makes the LT3014 an ideal choice. Quiescent current is
also well controlled in dropout.
Other features of the LT3014 include the ability to operate
with very small output capacitors. The regulators are stable
with only 0.47μF on the output while most older devices
require between 10μF and 100μF for stability. Small ceramic
capacitors can be used without the necessary addition of
ESR as is common with other regulators. Internal protec-
tion circuitry includes reverse-battery protection, current
limiting, thermal limiting and reverse current protection.
The device is available as an adjustable device with a 1.22V
reference voltage. The LT3014 regulator is available in the
5-lead ThinSOT and 8-lead DFN packages.

The l denotes the specifi cations which apply over the full operating
temperature range, otherwise specifi cations are at T
J
= 25°C.
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 LT3014 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 LT3014 is
tested and specifi ed for these conditions with an external resistor divider
(249k bottom, 392k top) for an output voltage of 3.3V. The external
resistor divider adds 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 is equal to (V
IN
– V
DROPOUT
).
Note 6: GND pin current is tested with V
IN
= V
OUT
(nominal) and a current
source load. This means the device is tested while operating in its dropout
region. This is the worst-case GND pin current. The GND pin current
decreases slightly at higher input voltages.
Note 7: ADJ pin bias current fl ows into the ADJ pin.
Note 8: SHDN pin current fl ows out of the SHDN 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 of the GND pin.
Note 10: The LT3014 is tested and specifi ed under pulse load conditions
such that T
J
≅ T
A
. The LT3014E is 100% tested at T
A
= 25°C. Performance
at –40°C to 125°C is assured by design, characterization, and statistical
