Devices in the both series are ideal for portable applications where space is at a premium such as mobile phones, portable games, cameras, portable AV equipment and PDAs. Already available in an ultra small USP-6C package and small SOT-25, the XC6415 device uses the USPN-6 package that measures just 1.3mm x 1.3mm x 0.4mm. In addition to USP-4, SOT-25 and SSOT-24 packages, the XC6221 Series single output LDO uses the even smaller USPN-4 package; measuring an incredible 0.9mm x 1.2mm x 0.4mm it is the smallest and thinnest package ever developed by Torex.
The XC6415 and XC6221 Series feature an ON/OFF function. Each output voltage of both series can be set internally by laser trimming in 0.05V increments within a range of 0.8V to 5.0V. By using the EN pin, devices in the XC6415 and XC6221 Series can be put into standby mode and the power supply current can be reduced to less than 0.1µA. This function enables the electric charge at the output capacitor (CL) to be discharged via the internal auto-discharge resistor, and as a result the VOUT pin quickly returns to the VSS level. In addition, the output stabilisation capacitor is compatible with low ESR ceramic capacitors.
