M62293

MITSUBISHI(Standard Linear ICs) M62293FP 3.3V, 2.5V FIXED 2-OUTPUT VOLTAGE DC-DC CONVERTER DESCRIPTION M62293FP is 3.3V and 2.5V fixed stable 2-output step-down DC-DC converter. It is possible to simplify peripheral circuit and to design compact and low cost sets because this device includes peripheral devices 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), therefore an application system is protected system errors. Especially this is most suitable for application sysytem with microprocessor and ASIC.
