Example) In case of Vo=5.3V Operation Notes Vo>5V , R4=37.6092 / (5.3-5 )k An excessively large capacitance at C2 may cause the output to become inactive. Therefore, a capacitance between 500 to 2200F is recommended, with a rise time of 10us or Operation Notes =125.364k less. Thus, R3=open An excessively large capacitance at C4 may cause the output to become inactive. The capacitance of C3 should be 10F, since an excessively small value will result in malfunction. The activation time is defined as : t(s)=R2*C3 ln 1-17/(VI-30A*R2) , where VI is R4=120k (Vo=5.313V) Therefore, a capacitance between 470 F to 2200 F is recommended, with a risetime of 10ms or less. the DC voltage after smoothing. DC coltage after sousing The resistance of R2 should be 1.5M, since an excessively small value will result in malfunction. Overcurrent (reset type) protection circuit is built in, preventing damage from occurring due to unexpected conditions Overcurrent (reset type) and overvoltage (latch type) protection circuits are built in, preventing damage from occurring due to unexpected conditions. The overvoltage protection circuit shuts down operation once VDD exceeds 20V. In order to reset the input capacitor C4 must be discharged and the power turned back on. www.rohm.com 2010.01 - Rev.A 2010 ROHM Co., Ltd. All rights reserved. 1/1 0.41.0 21.5MAX.
