The AS9195 is a CMOS low dropout, low noise,
low power consumption, low quiescent current
positive linear regulator with wide input voltage
range. The AS9195 can deliver a guaranteed 500mA
load current with a low dropout voltage. Quiescent
current of only 1.5uA makes these devices ideal for
powering the battery-powered, always-on systems
that require very little idle-state power dissipation to a
longer service life. There is an option of shutdown
function by selecting the parts with the EN pin and
pulling it low. The off state of AS9195 that consumes
less than 0.1uA during shutdown mode.
The AS9195 is designed and optimized to work
with low cost ceramic capacitors 1.0uF, which
consumes less than 0.1μA during shutdown mode.
Besides, its current limit protection and on-chip
thermal shutdown function provide protection against
any combination of over-load or ambient temperature
which could cause junction temperature exceeding
maximum rating.
The space-saving tiny SOT23-3L, SOT23-5L and
SOT89-3L packages are attractive for hand-held
applications. The device is specified over an
ambient temperature range of -40˚C to 85˚C.
