CIN=Ceramic 1.0μF COUT=Ceramic 6.8μF R1511x001C Series VDD VFB VOUT GND CIN COUT CIN=Ceramic 1.0μF COUT=Ceramic 6.8μF R3 RFB NOTES CONCERNING EXTERNAL PARTS Phase Compensation In the R1511x Series, phase compensation is provided to secure stable operation even when the load current is varied. For this purpose, please make sure to use a COUT capacitor. 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. Depending on the capacitor size, manufacturer, and part number, the bias characteristics and temperature characteristics are different. Evaluate the circuit taking actual characteristics into account. PCB Layout and GND Wiring Ensure the VDD and GND lines are sufficiently robust. If their impedance is too high, noise pickup or unstable operation may result. Connect a CIN capacitor with 1.0µF or more value between the VDD and GND pins, and as close as possible to the pins. Likewise, connect a COUT capacitor with suitable values between the VOUT and GND pins, and as close as possible to the pins (Please refer to the Typical Application above). In the case of using HSOP-6J package, please make sure to wire No. 2, No. 3, and No. 5 pins to the GND plane. Also, in the case of using TO-252-5-P2 package, please make sure to wire No. 2 and No. 3 pins to the GND plane. Thermal Shutdown R1511x contains a thermal shutdown circuit, which stops regulator operation if the junction temperature of R1511x becomes higher than 160ºC (Typ.). Additionally, if the junction temperature after the regulator being stopped decreases to a level below 135ºC (Typ.), it restarts regulator operation. As a result the operation of the thermal shutdown circuit causes the re gulator repeatedly to turn off and on until the causes of overheating are removed. As a consequence a pulse shaped output voltage occurs. Output Voltage Setting Method (R1511x001C) R1511x001C can be adjusted the output voltage up to 12.0V by using the external divider resistors. The output voltage can be calculated by the following equation. V OUT=VFB×(R2+R3)/R3 However, output voltage will be as large as “R 2×IFB” by the current flowing through the resistor in the IC. Because IFB = VFB/RFB, “R2×IFB” cause of error is as follows. R 2×IFB=R2×VFB/RFB=VFB×R2/RFB For better accuracy, choosing R2<<R FB reduces this error. R FB of R1511x is approximately min 1.0M Ω (guaranteed by design).

EFFECTIVE SERIES RESISTANCE (ESR) VS. OUTPUT CURRENT Ceramic type output capacitor is recommended for this seri es; however, the other output capacitors with low ESR also can be used. As for reference, the below gr aphs show the relationship between output current (I OUT) and effective series resistance (ESR). T he noise level of the output current (I OUT) was measured by the test circuit and is lower than the specified value.
