New Micropower, Low Dropout Regulators Ease Battery
Supply Designs вЂ“ Design Note 121
Mitchell Lee and John Seago
Three new linear regulators simplify the design of
battery-operated equipment. The LTВ®1521 is a 300mA,
positive low dropout regulator with micropower quiescent current and shutdown. The LT1175 is a 500mA
negative complement with adjustable current limit. A
third product, the LT1118, has the unique capability of
maintaining output regulation while sourcing or sinking
load current.
The LT1521 contains all of the features associated
with battery-operated applications. In designs where
memory must be powered continuously, the LT1521вЂ™s
12ОјA quiescent current eliminates the need for a
separate micropower backup supply. In shutdown the
quiescent current drops to 6ОјA. Figure 1 shows an
example application using the LTC В®1477 as a means
of disconnecting all circuitry except for memory and
ON/OFF control logic. The LTC1477 protected high
side switch draws only 10nA in shutdown, eliminating
itself as well as its load as a factor in battery shelf life.
In battery-backed memory applications, the output of
the LT1521 can be held up by the backup battery while …
