ABSOLUTE MAXIMUM RATINGS Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the permanent damages and may degrade the lifetime and safety for both device and system using the device in the field. The functional operation at or over these absolute maximum ratings are not assured. RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS) All of electronic equipment should be designed that the mounted semiconductor devices opera te within the recommended operating conditions. The semiconductor devices cannot operate normally over the recommended operating conditions, even if when they are used over such conditions by momentary electronic noise or surge. And the semiconductor devic es may receive serious damage when they continue to operate over the recommended operating conditions.

NO.EA-332-160720 TYPICAL APPLICATIONS C1 R1524x VDD VOUT CE GND C1 = Ceramic 0.1 µF C2 = Ceramic 0.1 µF VOUT R1524x Typical Applications TECHNICAL NOTES Phase Compensation In the R1524x, phase compensation is provided to secure stable operation even when the load current is varied. For this purpose, make sure to use 0.1 μF or more of a capacitor (C2). In case of using a tantalum type capacitor and the ESR (Equivalent Series Resistance) value of the capacitor is large, the output might be unstable. Evaluate the circuit including consideration of frequency characteristics. Connect 0.1 μF or more of a capacitor (C1) between VDD and GND, and as close as possible to the pins. PCB Layout For SOT-23-5 package type, wire the following GND pins together: No. 1 and No. 2 For SOT-89-5 package type, wire the following GND pins together: No. 2 and No. 4. For HSOP-6J package type, wire the following GND pins together: No. 2, No. 4, and No. 5. Thermal Shutdown R1524x has a built-in thermal shutdown circuit, which stops the regulator operation if the junction temperature of this device increases to 160°C (Typ.) or higher. If the temperature drops to 135°C (Typ.) or lower, the regulator restarts the operation. Unless eliminating the overheating problem, the regulator turns on and off repeatedly and as a result, a pulse shaped output voltage is generated.

NO.EA-332-160720 Input Transient/Load Transient vs. Output Capacity (C2) R1524 performs a stable operation by using 0.1 µF of ceramic capacitor as the output capacitor. However, the variation of output voltage may not meet the demand of the system when input voltage and load current vary. In such cases, the variation of output voltage can be minimized significantly by using 10 µF or higher ceramic capacitor. When using a high-capacity electrolytic capacitor for the output line, place the electrolytic capacitor a few centimeters apart from the IC after arranging the ceramic capacitor close to the IC.
