AS1369
200mA Ultra-Compact Low Dropout Regulator

Datasheet
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 fully operational 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 1.2V and 5.0V in 100mV
steps are available and the minimum input voltage is as low as 2.0V
(depending on the output voltage version), so the component can be
used with the new and emerging battery technologies.
The AS1369 is available in a 4-bump WL-CSP package.
