    Switching Regulator in
    SOT-23 and DFN Packages
    FEATURES DESCRIPTION n The LT В®1933 is a current mode PWM step-down DC/DC
    converter with an internal 0.75A power switch, packaged
    in a tiny 6-lead SOT-23. The wide input range of 3.6V
    to 36V makes the LT1933 suitable for regulating power
    from a wide variety of sources, including unregulated wall
    transformers, 24V industrial supplies and automotive
    batteries. Its high operating frequency allows the use of
    tiny, low cost inductors and ceramic capacitors, resulting
    in low, predictable output ripple. n Wide Input Range: 3.6V to 36V
    5V at 600mA from 16V to 36V Input
    3.3V at 600mA from 12V to 36V Input
    5V at 500mA from 6.3V to 36V Input
    3.3V at 500mA from 4.5V to 36V Input
    Fixed Frequency 500kHz Operation
    Uses Tiny Capacitors and Inductors
    Soft-Start
    Internally Compensated
    Low Shutdown Current: <2ОјA
    Output Adjustable Down to 1.25V ...
