DescripTion
The LT
(LDO) linear regulators that operate over a 1.6V to 45V
input supply range. The devices supply 100mA of output
current with a typical dropout voltage of 300mV. A single
external capacitor provides programmable low noise refer-
ence performance and output soft-start functionality. The
LT3060’s quiescent current is merely 40μA and provides
fast transient response with a minimum 2.2μF output
capacitor. In shutdown, quiescent current is less than 1μA
and the reference soft-start capacitor is reset.
The LT3060 regulators optimize stability and transient
response with low ESR, ceramic output capacitors.
The regulators do not require the addition of ESR as is
common with other regulators.
Internal protection circuitry includes reverse-battery
protection, reverse-output protection, reverse-current
protection, current limit with foldback and thermal
shutdown. The LT3060 series are available in fixed output
voltages of 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5V, and as an
adjustable voltage regulator with an output voltage range
from the 600mV reference to 44.5V. The LT3060 regulators
are offered in the thermally enhanced 8-lead TSOT-23 and
8-lead (2mm × 2mm × 0.75mm) DFN packages.
