R1524x has a built-in thermal shutdown circuit, which stops the regulator operation if the junction temperature of this device increases to 1 60°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.

C1 = Ceramic 0.1 µF C2 = Ceramic 0.1 µF VOUT CE Control R1524x Typical Applications TYPICAL APPLICATION FOR IC CHIP BREAKDOWN PREVENTION C1 R1524x VDD VOUT CE GND C1 = Ceramic 0.1 µF C2 = Ceramic 0.1 µF VOUT CE Control R1524x Typical Application for IC Chip Breakdown Prevention When a sudden surge of electrical current travels along the VOUT pin and GND due to a short-circuit, electrical resonance of a circuit involving an output capacitor (C2) and a short circuit inductor generates a negative voltage and may damage the device or the load devices. Connecting a schottky diode (D1) between the V OUT pin and GND has the effect of preventing damage to them.
No. EC -332-200602 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.

No. EC -332-200602 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 an electrolytic capacitor for the output line, place the electrolytic capacitor outer side of the ceramic capacitor arranged close to the IC.
