DC to DC Converter, Voltage Regulator and Piezoelectric Horn Driver
Product Specification
General Description
The RE46C107 is intended for use in 3V or 4.5V
battery or battery-backed applications. The circuit
features a DC-to-DC up-converter and driver circuit
suitable for driving a piezoelectric horn. A selectable
3.0V or 3.3V regulator is also provided for
microprocessor voltage regulation. An LED driver
and low battery detection and signaling are also
available.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are
stress ratings only and operation at these conditions for extended periods may affect device reliability.
This product utilizes CMOS technology with static protection; however proper ESD prevention procedures should be used
when handling this product. Damage can occur when exposed to extremely high static electrical charge
