December. 2002 (Rev.0) - 5 - IP1525 DUAL OUTPUT VOLTAGE LDO REGULATOR www.interpionsemi.com APPLICATION SUMMARY - ON / OFF When you want to control output of the IP1525, use pin #2 as follows As shown in figure Pin#2 is positive input of the comparator, and the other Input is threshold voltage. If the voltage of the pin#2 rises above threshold voltage, then TR Q1 will be saturated and the main bias current will be shut down. Pin#2 Vth Main bias
