AS1369 D a ta S he e t 2 0 0 m A U l t r a - C o m pa c t L o w D r o p o u t R e g u l a t o r 1 General Description 2 Key Features 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 0.47µF 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. ! Low Dropout Voltage: typ. 40mV @ 100mA ! 200mA High Maximum Load Current ! 2.0 to 5.5V Input Voltage ! 1.2 to 5.0V Output Voltage (in 100mV steps) ! High Accuracy: ±2% Over Temperature ! Thermal and Over Current Protection ! 25µA Quiescent Current ! <0.1µA Standby Current ! High PSRR: 72dB @ 1kHz ! No Noise Bypass Capacitor Required ! Low Noise: 30µVRMS ! Enable Pin ! Package: 4-bump WL-CSP 0.5mm pitch 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. 3 Applications The device is ideal for mobile communication, battery powered systems and any electronic equipment. Figure 1.

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.

The lead finish for Pb-free leaded packages is matte tin (100% Sn). +260 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 (ΘJA), and the ambient temperature (TAMB). The maximum allowable power dissipation at any ambient temperature is calculated as: P(MAX) = (TJ(MAX) - (TAMB))/ΘJA (EQ 1) Where: The value of ΘJA for the WLP package is 345°C/W. Note: Exceeding the maximum allowable dissipation will cause excessive device temperature and the regulator will go into thermal shutdown. The AS1369 uses an internal protective structure against light influence. However, exposing the WLP package to direct light could cause device malfunction. www.austriamicrosystems.com Revision 1.03 3 - 16 AS1369 Data Sheet - E l e c t r i c a l C h a r a c t e r i s t i c s 6 Electrical Characteristics TAMB = -40 to 85ºC , VIN = VOUT(NOM) + 0.5V, COUT = CIN = 0.47µF, IOUT = 1mA, VIH = 1.2V (unless otherwise specified) Table 3.
