IC for CMOS Regulator+Reset
Monolithic IC MM3018
Outline
This is a reset + regulator composite IC developed using the CMOS process. The CMOS process is used to achieve ultra-low current consumption, aiming at use in memory cards and portable devices. Further, this exceptional IC can be used even when board mounting space is limited, due to the wafer level package, WLCSP-6.
Features
1. Built-in thermal shutdown circuit 2. Built-in current limit circuit 3. Low current consumption 15µA typ. 4. Series with reset detection voltage in 0.1V steps 5. Delay time from voltage detection to reset release can be set easily.
Package
WLCSP-6
Applications
1. Microcomputer, CPU and MPU reset circuit 2. Logic circuit reset circuit 3. Battery voltage check 4. Back-up circuit switching circuit 5. Level detection circuit 6. Mechanical system reset circuit

(BOTTOM VIEW) Note 1. An output-capacitor recommended the capacitor with more than 1.0µF and B type temperature characteristics. 2. The wire of VDD and GND is required to print full ground plane for noise and stability. 3. The input capacitor must be connected a distance of less than 1cm from input pin. 4. In case the output voltage is above the input voltage, the overcurrent flow by internal parasitic diode from output to input.
