All rights reserved. www.rohm.com TSZ22111・15・001 21.Feb.2014 Rev.002 Input-to-Output Capacitor It is recommended that a capacitor is placed nearby pin between Input pin and GND, output pin and GND. A capacitor, between input pin and GND, is valid when the power supply impedance is high or drawing is long. Also as for a capacitor, between output pin and GND, the greater the capacity, more sustainable the line regulation and it makes improvement of characteristics by load change. However, please check by mounted on a board for the actual application. Ceramic capacitor usually has difference, thermal characteristics and series bias characteristics, and moreover capacity decreases gradually by using conditions. For more detail, please be sure to inquire the manufacturer, and select the best ceramic capacitor. Equivalent Series Resistance ESR (ceramic capacitor etc.) Please attach an anti-oscillation capacitor between VO and GND. Capacitor usually has ESR(Equivalent Series Resistance), and operates stable in ESR-IO range, showed right. Generally, ESR of ceramic, tantalum and electronic capacitor etc. is different for each, so please be sure to check a capacitor which is going to use, and use it inside the stable operating region, showed right. Then, please evaluate for the actual application.
