Data Sheet
1 General Description
The AS1369 is an ultra compact high-performance low-
dropout 200mA voltage regulator designed for use with
very-low ESR output capacitors. The device can deliver
superior performance in all specifications critical to
battery-powered designs, and is perfectly suited for
mobile phones, PDAs, MP3 players, and other battery
powered devices.
The AS1369 is working with small input and output
capacitor of only 0.47µF offering PSRR of 72dB typical
and a noise level of 30µVRMS.
Typical quiescent current is around 25µA while in
shutdown the AS1369 requires less than 0.1µA
quiescent current.
Regulation performance is excellent even under low
dropout conditions, when the power transistor has to
operate in linear mode.
The AS1369 offers excellent low-noise performance
requiring no external bypass capacitance.
Multiple output voltage options between 1.2 and 5.0V in
100mV steps are available and the the minimum input
voltage is as low as 2.0V (depending on the output
voltage version), so the component can be used with the
coming new battery technologies.
The AS1369 is available in a 4-bump WL-CSP package.
