7 TYPICAL APPLICATIONS VDD VOUT VOUT C1 R1524x C2 CE GND R1524x Typical Applications C1 = Ceramic.1 µf C2 = Ceramic.1 µf 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.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.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 16 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. 7

8 TYPICAL APPLICATION FOR IC CHIP BREAKDOWN PREVENTION VDD VOUT VOUT C1 R1524x C2 D1 CE GND C1 = Ceramic.1 µf C2 = Ceramic.1 µf 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 VOUT pin and GND has the effect of preventing damage to them. 8
