5V LDO Regulator with 2ch RESET - BD4269FJ-C

BD4269FJ-C is an automotive suited voltage regulator with Power on and under-voltage reset and Input voltage reset for VCC or other voltage and offers the output current of 200 mA while limiting the low quiescent current. This device provides ideal solution to lower the current consumption as well as to simply the use with battery direct-connected systems. Power on and under-voltage reset and Input voltage reset threshold voltage can be adjusted by external resistance.
Power on and under-voltage reset delay time can programmed set by external capacitor.
