MIC5392/3 High-Performance Dual 150mA LDO General Description Features The MIC5392/3 is a tiny dual low-dropout linear regulator ideally suited for portable electronics. It is ideal for general purpose/digital applications which require high-power supply ripple rejection (PSRR) >60dB, eliminating the need for a bypass capacitor and providing two enable pins for maximum flexibility. The MIC5392/3 integrates two highperformance; 150mA LDOs into a tiny 6-pin, 1.2mm × 1.2mm leadless DFN package, which provides exceptional thermal package characteristics. • 2.5V to 5.5V input voltage range • Two 150mA output current LDOs • High output accuracy − ±2% initial accuracy • Low quiescent current (32µA per LDO) • Stable with 1µF ceramic output capacitors • Independent enable pins • Low dropout voltage (155mV at 150mA) • Thermal-shutdown protection • Current-limit protection • Internal 25Ω output discharge circuit (MIC5393) • 1.2mm × 1.2mm Extra Thin DFN package (H ≤ 0.4mm) • 1.2mm × 1.2mm Thin DFN package The MIC5392/3 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 low-drop-out voltage, high power supply rejection and exceptional thermal package characteristics makes it ideal for powering mobile phones camera modules, image sensors, PDAs, MP3 players and audio codec power applications. The MIC5392/3 is available in fixed-output voltages in the tiny 6-pin 1.2mm × 1.2mm leadless DFN package which is 2 only 1.44mm in area. Additional voltage options are available.

Application Information MIC5392/3 is a dual 150mA LDO in a small 1.2mm × 1.2mm package. The MIC5393 includes an autodischarge circuit for each of the LDO outputs that are activated when the output is disabled. The MIC5392/3 regulator is fully protected from damage due to fault conditions through linear current limiting and thermal shutdown. 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. Thermal Considerations The MIC5392/3 is designed to provide 150mA 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. For example if the input voltage is 3.6V, the output voltage is 3.0V for VOUT1, 2.8V for VOUT2 and the output current = 150mA. The actual power dissipation of the regulator circuit can be determined using Equation 1: Input Capacitor The MIC5392/3 is a high-performance, high-bandwidth device. An input capacitor of 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. X5R or X7R dielectrics are recommended for the input capacitor. Y5V dielectrics lose most of their capacitance over temperature and are therefore, not recommended. Eq. 1 PD = (VIN – VOUT1) IOUT1 + (VIN – VOUT2) IOUT2 + VIN IGND Output Capacitor The MIC5392/3 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
