Torex Semiconductor has developed a new ultra-low supply current LDO regulator, the XC6504 series.
The XC6504 series are voltage regulators that operate at an ultra low supply current of only 0.6μA and are available in an ultra small USPN-4B02 package with dimensions of 0.75 × 0.95 × h0.4mm. Although a low ESR capacitor can be used for the output stabilizing capacitor (CL), stable operation is also possible without actually using CL due to internal phase compensation. Not using a CL capacitor results in a substantial reduction in board mounting area.
The output voltage is highly accurate even when the output current is 1μA (light load), making this series ideal for applications that require only a minimal output current. The output voltage can be selected in steps of 0.1V within the range 1.1V to 5.0V. The IC can be put into stand-by mode by applying a L level input to the CE pin and this reduces the supply current to 0.1μA or less. Current limiting and short-circuit protection are provided as protective circuits.
The ultra-small USPN-4B02 package, SSOT-24 package, or SOT-25 package can be selected to match the application. This series is an environment-friendly product that complies with the EU RoHS Directive and is Pb-free.
