The capacitance values will differ depending on the application, so please take this into account when configuring the terminal. ・ GND Terminal Please be sure to keep the set ground and IC ground at the same potential level so that a potential difference does not arise between them. If a potential difference arises between the set ground and the IC ground, the preset voltage will not be outputted, causing the system to become unstable. Therefore, please reduce the impedance by making the ground patterns as wide as possible and by reducing the distance between the set ground and the IC ground as much as possible. ・ CTL Terminal The CTL terminal is turned ON at 2.0V and higher and OFF at 0.8V and lower within the operating power supply voltage range. The power supply and the CTL terminal may be started up and shut down in any order without problems. ● Vo Terminal Fig.32 Output Equivalent Circuit Fig.33 ESR-Io Characteristics Fig.34 ESR vs Io Characteristics (BA□□CC0) (B A□□DD0) Please attach an anti-oscillation capacitor between Vcc and GND. The capacitance of the capacitor may significantly change due to factors such as temperature changes, making it impossible to completely stop oscillations. Please use a tantalum capacitor or aluminum electrolysis capacitor with favorable characteristics and small internal series resistance (ESR) even at low temperatures. The output fluctuates regardless of whether the ESR is large or small. Please use the IC within the stable operating region while referring to the ESR characteristics reference data shown in Figs.32 through 34. In applications where there are sudden load fluctuations, the use of a capacitor with large capacitance is recommended.
