LDO Regulator Application Note

The High Input Voltage Regulator

The CMOS type regulator is now released in the high input voltage environment where only the bipolar type could previously operate. Since CMOS type voltage regulators require considerably lower supply current than the bipolar type, these are suitable for digital home appliances where energy saving is of importance. There are optional wide operating temperature range products available for car accessories such as car navigation and car audio systems. Ricoh's high input voltage regulators have a built in thermal shutdown circuit, to ensure safety for the circuit design.
