SLR1117 Technical Data Data Sheet N1575, Rev. - 800mA Low Dropout Positive Regulator Description: The SLR1117 is a low dropout, three terminals regulator designed to provide output current up to 800mA. The device is available in an adjustable version and fixed output voltage of1.8V, 2.5V and 3.3V. Dropout voltage of maximum of 1.4V is guaranteed at 800mA output current. The quality of low dropout voltage and fast transient response make this device ideal for low voltage microprocessor applications. The SLR1117 requires output capacitance of a minimum of 10μF for stability. Built-in output current limiting and thermal limiting provide maximal protection to the SLR1117 against fault conditions.

SLR1117 800mA Low Dropout Positive Regulator Technical Data Data Sheet N1575, Rev. - Application Information INPUT-OUTPUT CAPACITORS Linear regulators require input and output capacitors to maintain stability. Input capacitor at 10μF with a 10μF aluminum electrolytic output capacitor is recommended. To avoid oscillation, it is recommended to follow Fig. 8, 9 to choose proper capacitor specifications. POWER DISSIPATION The SLR1117 obtains thermal-limiting circuitry, which is designed to protect the device against overload condition. For continuous load condition, maximum rating of junction temperature must not be exceeded. It is important to pay more attention in thermal resistance. It includes junction to case, junction to ambient. The maximum power dissipation of SLR1117 depends on the thermal resistance of its case and circuit board, the temperature difference between the die junction and ambient air, and the rate of airflow. The rate of temperature rise is greatly affected by the mounting pad configuration on the PCB, the board material, and the ambient temperature. When the IC mounting with good thermal conductivity is used, the junction temperature will be low even when large power dissipation applies. The power dissipation across the device is P = I (V -V ). OUT IN OUT The maximum power dissipation is: (TJ-max - TA) PMAX = RΘJA is the maximum allowable junction temperature (125°C), and T is the ambient temperature Where T J-max A suitable in application. As a general rule, the lower temperature is, the better reliability of the device is. So the PCB mounting pad should provide maximum thermal conductivity to maintain low device temperature.
