The XCM406 Series multi-chip module (MCM) from Torex Semiconductor combines two XC6210 high current, high speed LDO (low dropout) regulators in an ultra small USP-12B01 (2.8mm x 2.3mm x 0.6mm) package. With high performance, reliability and very low power consumption, these highly integrated devices meet the needs of battery-driven applications such as mobile phones, Bluetooth equipment, portable gaming devices and other portable equipment.
The IC operates from a supply voltage within a range of 1.5V to 6.0V to provide output voltages of between 0.8V and 5.0V (accurate to ±2%), with an ultra low dropout of just 50mV at 100mA. It can safely handle load currents in excess of 700mA per channel. A high ripple rejection of 60dB @ 1kHz and extremely fast transient response make the XCM406 ideal for noise sensitive applications. For extra output stability, the device is fully compatible with low ESR ceramic capacitors.
Manufactured using Torex’s CMOS process, the two LDO regulators feature a voltage reference, an error amplifier, a current limiter foldback circuit and a phase compensation circuit, plus a driver transistor. The foldback current limit circuit also operates as the output current limiter (800mA max) and the output pin protector.
The low ON resistance of the driver transistor allows batteries to be used to a minimal input to output voltage differential, and therefore for a much longer time before replacement is necessary in the end equipment.
Power consumption is just 35µA per channel typical. A chip enable (CE) function allows the output of each LDO to be turned off, putting the device into standby mode and reducing power consumption to a maximum of 0.1µA. Operating temperature range is -40 to +85°C.
