MIC5330-SRYML-TR

MIC5330 Dual 300mA µCap LDO in 2mm x 2mm MLF® General Description Features The MIC5330 is a tiny Dual Ultra Low Dropout (ULDO™) linear regulator ideally suited for portable electronics due to its high power supply ripple rejection (PSRR) and ultra low output noise. The MIC5330 integrates two high performance 300mA ULDOs into a tiny 2mm x 2mm leadless MLF® package, which provides exceptional thermal package characteristics. The 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 ULDO™ 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. For more information, contact Micrel marketing department.

MIC5330 Functional Characteristics March 2011 7 M9999-032311-C Micrel, Inc. MIC5330 Applications Information Enable/Shutdown The 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. bypass capacitance. A unique, quick start circuit allows the MIC5330 to drive a large capacitor on the bypass pin without significantly slowing turn on time. No-Load Stability Unlike many other voltage regulators, the MIC5330 will remain stable and in regulation with no load. This is especially important in CMOS RAM keep alive applications. Thermal Considerations The 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: Input Capacitor The 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 high frequency capacitors, such as small valued NPO dielectric type capacitors, help filter out high frequency noise and are good practice in any RF based circuit. PD = (VIN – VOUT1) IOUT1 + (VIN – VOUT2) IOUT2+ VIN IGND Output Capacitor The 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. X7R/X5R dielectric type ceramic capacitors are recommended because of their temperature performance. X7R type capacitors change capacitance by 15% over their operating temperature range and are the most stable type of ceramic capacitors. Z5U and Y5V dielectric capacitors change value by as much as 50% and 60%, respectively, over their operating temperature ranges. To use a ceramic chip capacitor with Y5V dielectric, the value must be much higher than an X7R ceramic capacitor to ensure the same minimum capacitance over the equivalent operating temperature range. Because this device is CMOS and the ground current is typically
