    SOT89-3L

    General Description

        The AS9125 is a CMOS low dropout, low noise, low power consumption, low quiescent current positive linear regulator with wide input voltage range. The AS9125 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 AS9125 that consumes less than 0.1uA during shutdown mode.

         The AS9125 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.
