General Description

    The AS9134A is a CMOS low dropout, low noise, low power consumption, low quiescent current positive linear regulator with wide input voltage range. The AS9134A can deliver a guaranteed 400mA load current with a low dropout voltage. Quiescent current of only 2.0uA 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.
    The device is suitable for portable application such as cellular handsets or PDA. 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 AS9134A includes a reference bypass pin in order to reduce output noise and a logic control shut-down input.
    The space-saving SOT89-3L packages are attractive for hand-held applications. The device is specified over an ambient temperature range of -40˚C to 125˚C.
