LDO Regulators :Single Output CMOS Type

CMOS LDO regulators are now available in the WCSP4 ultra-small package
The WCSP4 package occupies only 0.63 mm2 of board area and is thus ideal for applications that require high-density board assembly. The CMOS LDO regulators in the WCSP4 package are available with a fixed output voltage between 1.2 V and 3.6 V. The output voltage is able to fix in steps of 50 mV. The TCR4SxxDWBG Series provides an auto-discharge function, which makes it ideal for applications with complex timing control.
