MIC5330 MIC5330 Dual, 300mA µCap LDO in 2mm x 2mm MLF® General Description Features The MIC5330 MIC5330 is a tiny Dual Ultra Low-Dropout (ULDOTM) linear regulator ideally suited for portable electronics due to its high power supply ripple rejection (PSRR) and ultra low output noise. The MIC5330 MIC5330 integrates two high-performance; 300mA ULDOs into a tiny 2mm x 2mm leadless MLF® package, which provides exceptional thermal package characteristics. The MIC5330 MIC5330 is a µCap design which enables operation with very small ceramic output capacitors for stability, thereby reducing required board space and component cost. The combination of extremely low-drop-out voltage, high power supply rejection and exceptional thermal package characteristics makes it ideal for powering RF/noise sensitive circuitry, cellular phone camera modules, imaging sensors for digital still cameras, PDAs, MP3 players and WebCam applications. The MIC5330 MIC5330 ULDOTM is available in fixed-output voltages in the tiny 8-pin 2mm x 2mm leadless MLF® package which occupies less than half the board area of a single SOT-6 package. Additional voltage options are available.

MIC5330 MIC5330 Applications Information low-noise outputs. The bypass capacitor can be increased, further reducing noise and improving PSRR. Turn-on time increases slightly with respect to bypass capacitance. A unique, quick-start circuit allows the MIC5330 MIC5330 to drive a large capacitor on the bypass pin without significantly slowing turn-on time. Enable/Shutdown The MIC5330 MIC5330 comes with dual active-high enable pins that allow each regulator to be enabled independently. Forcing the enable pin low disables the regulator and sends it into a "zero" off-mode-current state. In this state, current consumed by the regulator goes nearly to zero. Forcing the enable pin high enables the output voltage. The active-high enable pin uses CMOS technology and the enable pin cannot be left floating; a floating enable pin may cause an indeterminate state on the output. No-Load Stability Unlike many other voltage regulators, the MIC5330 MIC5330 will remain stable and in regulation with no load. This is especially important in CMOS RAM keep-alive applications. Input Capacitor The MIC5330 MIC5330 is a high-performance, high bandwidth device. Therefore, it requires a well-bypassed input supply for optimal performance. A 1µF capacitor is required from the input to ground to provide stability. Low-ESR ceramic capacitors provide optimal performance at a minimum of space. Additional highfrequency capacitors, such as small-valued NPO dielectric-type capacitors, help filter out highfrequency noise and are good practice in any RFbased circuit. Thermal Considerations The MIC5330 MIC5330 is designed to provide 300mA of continuous current for both outputs in a very small package. Maximum ambient operating temperature can be calculated based on the output current and the voltage drop across the part. Given that the input voltage is 3.3V, the output voltage is 2.8V for VOUT1, 2.5V for VOUT2 and the output current = 300mA. The actual power dissipation of the regulator circuit can be determined using the equation: PD = (VIN ­ VOUT1) IOUT1 + (VIN ­ VOUT2) IOUT2+ VIN IGND Output Capacitor The MIC5330 MIC5330 requires an output capacitor of 1µF or greater to maintain stability. The design is optimized for use with low-ESR ceramic chip capacitors. High ESR capacitors may cause high frequency oscillation. The output capacitor can be increased, but performance has been optimized for a 1µF ceramic output capacitor and does not improve significantly with larger capacitance. Because this device is CMOS and the ground current is typically
