M62294FP

MITSUBISHI(Standard Linear ICs) M62294FP 3.3V, 2.0V FIXED 2-OUTPUT VOLTAGE DC-DC CONVERTER DESCRIPTION M62293FP is 3.3V and 2.5V f ixed stable 2-output step-down DC-DC conv erter. It is possible to simplif y peripheral circuit and to design compact and low cost sets because this dev ice includes peripheral dev ices in small size 8pin package. The IC also has Reset circuit with time delay that monitors power supply (Vcc=5V) and one regulator output(Vout1=3.3V;IN1 terminal), theref ore an application sy s t em is protected system errors. Especially this is most suitable f or application sy s y t em with microprocessor and ASIC.
