DS20006525A-page 8 Description  2021 Microchip Technology Inc. MIC5380/1 4.0 APPLICATION INFORMATION MIC5380/1 is a dual 150 mA LDO in a small 1 mm x 1 mm FTQFN package. The MIC5381 includes an auto-discharge circuit for each of the LDO outputs that is activated when the output is disabled. The MIC5380/1 regulator is fully protected from damage due to fault conditions through linear current limiting and thermal shutdown. 4.1 Input Capacitor The MIC5380/1 is a high-performance, high bandwidth device. An input capacitor of 1 µF 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. 4.2 Output Capacitor The MIC5380/1 requires an output capacitor of 1 µF 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 1 µF 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. 4.3 4.4 Enable/Shutdown The MIC5380/1 comes with two active-high enable pins that allow each regulator to be disabled 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. When disabled the MIC5381 switches a 30Ω (typical) load on the regulator output to discharge the external capacitor. 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. 4.5 Thermal Considerations The MIC5380/1 is designed to provide 150 mA of continuous current for both outputs in a very small package. Maximum ambient operating temperature can be calculated based upon the output current and the voltage drop across the part. For example, if the input voltage is 3.6V, and the output voltage 3.0V for VOUT1, 3.0V for VOUT2 and output current equals 150 mA, then the actual power dissipation of the regulator circuit can be calculated using the equation: EQUATION 4-1: P D =  V IN – V OUT1 I OUT1 +  V IN – V OUT2 I OUT2 + V IN I GND Because this device is CMOS and the ground current is typically
