Current limit and on chip thermal shutdown features provide protection against any combination of overload or ambient temperature which exceeds maximum junction temperature. Output Voltage Setting The output can be set to fixed or adjustable mode. The internal output mode comparator compares the ADJ pin voltage with 166mV reference. If the ADJ pin voltage is higher than 166mV, the FP6166 will be set into adjustable output mode and the non-inverting input of the error amplifier will be connected to the external voltage divider. If the ADJ pin voltage is lower than 166mV, the FP6166 will be set into fixed output mode and the non-inverting input of the error amplifier will be connected to the internal voltage divider. The output voltage VOUT is set by using a resistive divider R1 and R2. Thus the output voltage is: V T =1V 1 R1 R Protection Features In order to prevent overloading or thermal condition damaging the device, FP6166 contains internal thermal and current limit functions which are designed to protect the device. It will rapidly shut off PMOS pass element during over-temperature condition. Thermal Consideration The power handling capability of the device will be limited by allowable operation junction temperature (125ºC). The power dissipated by the device will be estimated by PD = IOUT  (VIN-VOUT). The power dissipation should be lower than the maximum power dissipation listed in “Absolute Maximum Ratings” section. Shutdown Operation The FP6166 will be shut down by pulling the input low and turned on by driving the high. If pin is floating, the FP6166 will shut down because pin has built-in a pull low resistor (refer to Block Diagram). Output and Input Capacitor The FP6166 regulator is designed to stabilize with a wide range of output capacitors. The ESR of the output capacitor affects stability. Larger value of the output capacitor decreases the peak deviations and improves transient response for larger current changes. The capacitor types (aluminum, ceramic and tantalum) have different characterizations such as temperature and voltage coefficients. All ceramic capacitors are manufactured with a variety of dielectrics, each with different behavior across temperature and applications. Common dielectrics used are X5R, X7R and Y5V. It is recommended to use 1µF to 10µF X5R or X7R dielectric ceramic capacitors with 30mΩ to 50mΩ ESR range between device outputs and ground for stability. The FP6166 is designed to stabilize with low ESR ceramic capacitors, and higher values of capacitors and ESR could improve output stability. The ESR of output capacitor is very important because it generates a zero to provide phase lead for loop stability. There is no requirement for the ESR on the input capacitor, but its voltage and temperature coefficient have to be considered for device application environment.
