The MIC5368 includes an auto-discharge circuit that is switched on when the regulator is disabled through the Enable pin. The MIC5367/8 regulators are fully protected from damage due to fault conditions, offering linear current limiting and thermal shutdown. 4.1 Input Capacitor The MIC5367/8 are high-performance, high bandwidth devices. An input capacitor of 1 µF 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 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. No-Load Stability Unlike many other voltage regulators, the MIC5367/8 will remain stable and in regulation with no load. This is especially important in CMOS RAM keep-alive applications. 4.4 4.5 Thermal Considerations The MIC5367/8 are designed to provide 150 mA of continuous current 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 3.3V, the output voltage is 1.5V, and the output current is 150 mA. The actual power dissipation of the regulator circuit can be determined using the following equation: EQUATION 4-1: P D =  V IN – V OUT1   I OUT + V IN  I GND Output Capacitor The MIC5367/8 require 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 are not recommended because they 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. 4.3 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. Enable/Shutdown The MIC5367/8 come with an active-high enable pin that allows the regulator to be disabled. 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.
