LDOs in low profile packaging

Torex Semiconductor's XC6415 series independently controlled, dual output and XC6221 series single output LDO voltage regulators are now available.

They are offered in USPN packaging to achieve higher density mounting. The packages are 0.4mm high and are suitable for a range of battery powered applications where small size and low power consumption are key design targets. Devices in the both series are suitable for portable applications where space is at a premium such as mobile phones, portable games, cameras, portable AV equipment and PDAs. Already available in a USP-6C package and small SOT-25, the XC6415 device uses the USPN-6 package that measures 1.3 x 1.3 x 0.4mm. In addition to USP-4, SOT-25 and SSOT-24 packages, the XC6221 series single output LDO uses a smaller USPN-4 package; measuring 0.9 x 1.2 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 0.8 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 to be discharged via the internal auto-discharge resistor, and as a result the Vout pin returns to the VSS level.
