1 General Description
The AS1369 is an ultra compact high-performance lowdropout 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 0.47F offering PSRR of 72dB typical and a noise level of 30VRMS. Typical quiescent current is around 25A while in shutdown the AS1369 requires less than 0.1A 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.

5 Absolute Maximum Ratings
Stresses beyond those listed in Table 2 may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in Electrical Characteristics on page 4 is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Table 2.

1. The output PNP structure contains a diode between pins VIN and VOUT that is normally reverse-biased. reversing the polarity of pins VIN and VOUT will activate this diode. 2. The maximum allowable power dissipation is a function of the maximum junction temperature (TJ(MAX), the junction-to-ambient thermal resistance (JA), and the ambient temperature (TAMB). The maximum allowable power dissipation at any ambient temperature is calculated as: P(MAX) = (TJ(MAX) - (TAMB))/JA Where: The value of JA for the WLP package is 345C/W. Note: Exceeding the maximum allowable dissipation will cause excessive device temperature and the regulator will go into thermal shutdown. (EQ 1)
The AS1369 uses an internal protective structure against light influence. However, exposing the WLP package to direct light could cause device malfunction.

1. Dropout voltage is the input-to-output voltage difference at which the output voltage is 100mV below its nominal value (does not apply to input voltages below 2.0V). 2. Turn on time is time measured between the enable input just exceeding the VEN high value and the output voltage just reaching 95% of its nominal value.
