The device can deliver superior performance in all 2.0V to 5.5V Input Voltage specifications critical to battery-powered designs, and is perfectly suited for mobile phones, PDAs, MP3 players, and other battery 1.2V to 5.0V Output Voltage (in 100mV steps) powered devices. High Accuracy: 2% Over Temperature The AS1369 is fully operational with small input and output capacitor Thermal and Over Current Protection of only 0.47F offering PSRR of 72dB typical and a noise level of 30VRMS. 25A Quiescent Current Typical quiescent current is around 25A while in shutdown the <0.1A Standby Current AS1369 requires less than 0.1A quiescent current. High PSRR: 72dB 1kHz Regulation performance is excellent even under low dropout No Noise Bypass Capacitor Required conditions, when the power transistor has to operate in linear mode. Low Noise: 30VRMS The AS1369 offers excellent low-noise performance requiring no external bypass capacitance. Enable Pin Multiple output voltage options between 1.2V and 5.0V in 100mV Package: 4-bump WL-CSP 0.5mm pitch 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 3 Applications used with the new and emerging battery technologies. The device is ideal for mobile communication, battery powered The AS1369 is available in a 4-bump WL-CSP package. systems and any electronic equipment. Figure 1.
