_15_V_FROM_HIGH_INPUT_VOLTAGE

Published:2009/7/6 3:08:00 Author:May | From:SeekIC

Zener is used in series with resistor R to level-shift input voltage higher than rated maximum of LM340K-15 regulator. Typical load regulation is 40 mV for 0-1 A pulsed load, and line regulation is 2 mV for 1-V change in input voltage for no load.With optional output capacitor, circuit noise is only 700 ptV P-P.- Linear Applications, Vol. 2, National Semiconductor, Santa Clara, CA, 1976, AN-103,p9-10.
