Packages
The LT ? 3027 is a dual, micropower, low noise, low drop-
out regulator with independent inputs. With an external
0.01 μ F bypass capacitor, output noise is a low 20 μ V RMS
over a 10Hz to 100kHz bandwidth. Designed for use in
battery-powered systems, the low 25 μ A quiescent current
per channel makes it an ideal choice. In shutdown, quies-
cent current drops to less than 0.1 μ A. Shutdown control
is independent for each channel, allowing for flexibility in
power management. The device is capable of operating
over an input voltage from 1.8V to 20V, and can supply
100mA of output current from each channel with a drop-
out voltage of 300mV. Quiescent current is well controlled
in dropout.
The LT3027 regulator is stable with output capacitors as
low as 1 μ F. Small ceramic capacitors can be used without
the series resistance required by other regulators.
Internal protection circuitry includes reverse battery pro-

The device is available as an adjustable device with a
1.22V reference voltage. The LT3027 regulator is available
in the thermally enhanced 10-lead MSOP and low profile
(0.75mm) 3mm × 3mm DFN packages.
