    Piezoelectric Horn Driver and Voltage Regulator
    Product Specification General Description Features The RE46C108 is a piezoelectric horn driver with a
    voltage regulator that can operate at 3.3V or 5V. It
    is intended for applications requiring a 9V horn
    driver with a low voltage logic supply. The horn
    feedback control pin is designed for use with selfoscillating piezoelectric horn but can also be used in
    direct drive applications. Applications
