BDxxIC0MEFJ-M is a LDO regulator with output current 1.0A. The output accuracy is ±1% of output voltage. With external resistance, it is available to set the output voltage at random (from 0.8V to 4.5V).It has package type: HTSOP-J8. Overcurrent protection (for protecting the IC destruction by output short circuit), circuit current ON/OFF switch (for setting the circuit 0µA at shutdown mode), and thermal shutdown circuit (for protecting IC from heat destruction by over load condition)are all built in. It is usable for ceramic capacitor and enables to improve smaller set and long-life.We recommendBD30IC0VEFJ-Mfor your new development. It uses different production lines for the purpose of improving production efficiency. Electric characteristics noted in Datasheet does not differ between Production Line.

ROHM's secondary LDO regulators were designed to maximize device characteristics and provide stable operation through low power consumption, increased miniaturization, and low noise. ROHM's 500mA fixed output secondary LDO regulators with shutdown switch for local power supplies features an output voltage accuracy of ±1% and low saturation. The shutdown switch enables a circuit current of 0uA during shutdown. The wide lineup includes a number of package types and output voltages, such as TVs, HDDs, PCs, and DVD players. In addition, multiple protection circuits are integrated (i.e. overcurrent, thermal shutdown), providing a high level of reliability.

BD3378MUV-M is a 22-channel Multiple Input Switch Monitor IC that detects the opening and closing of mechanical switches. Once it senses a change in the status of a switch, it sends an interrupt signal to the MCU via a serial peripheral interface (SPI). The 22 switch inputs have two types of power supply, VPUB and VPUA. The VPUB and the VPUA power supplies can either be from a battery or from another power supply system. VPUB is the supply for the INB inputs while VPUA is for the INZ and INA inputs. BD3378MUV-M has two modes of operation, Normal and Sleep. In both modes, the internal registers can be set to make the device perform either intermittent or continuous monitoring of the switches. In intermittent monitoring, the switch status is monitored at regular time intervals, allowing the IC to operate with low power consumption. Also, operation with reduced noise can be achieved by enabling uniform sequential monitoring of all switches or sequential monitoring by power supply system.

BD3381EKV-C is a 33-channel Multiple Input Switch Monitor IC that detects the opening and closing of mechanical switches. Once it senses a change in the status of a switch, it sends an interrupt signal to the MCU via a serial peripheral interface (SPI). The 33 switch inputs have two types of power supply, VPUB and VPUA. The VPUB and the VPUA power supplies can either be from a battery or from another power supply system. VPUB is the supply for the INB inputs while VPUA is for the INZ and INA inputs.

ROHM's LDO regulators continue the trend towards increasing miniaturization and greater power efficiency and are optimized for power supplies of all types. The broad lineup includes low saturation fixed output types in 1A/2A/0.3A ratings, models with different output voltages and packages, and units with/without a shutdown switch. In addition, overcurrent, thermal shutdown, and overvoltage protection circuits are integrated to prevent IC destruction due to output shorts, IC overload, and surges on the power supply line, respectively.
