R1540x NO.EA-513-190411 TYPICAL APPLICATIONTYPICAL APPLICATION VDD VOUT CIN R1540x COUT CE/ADJ GND CIN = Ceramic 0.1 µF CCE/ADJ COUT = Ceramic 10 µF CCE/ADJ = Ceramic 0.1 µF R1540x Typical ApplicationTECHNICAL NOTESPhase Compensation R1540x adopts capacitance and Equivalent Series Resistance (ESR) for phase compensation to ensure stable operation even with load varying current. For this end, the capacitor of 10 μF or more is essential. A certain amount of ESR may cause unstable output voltage. Fully take temperature and frequency characteristics into consideration when evaluating the circuit. Place the capacitor of 0.1 μF or more between VDD and GND with using short leads and short printed circuit traces. PCB Layout SOT-23-5 package: connect Nos. 2 and 5 of GND pin together. HSOP-8E package: connect Nos. 5 and 6 of GND pin together. 7
