    LT1934/LT1934-1
    Micropower Step-Down
    Switching Regulators
    in ThinSOT and DFN
    FEATURES DESCRIPTION n The LT ®1934 is a micropower step-down DC/DC converter
    with internal 400mA power switch, packaged in a low
    profile (1mm) ThinSOT. With its wide input range of 3.2V
    to 34V, the LT1934 can regulate a wide variety of power
    sources, from 4-cell alkaline batteries and 5V logic rails
    to unregulated wall transformers and lead-acid batteries.
    Quiescent current is just 12μA and a zero current shutdown mode disconnects the load from the input source,
    simplifying power management in battery-powered systems. Burst Mode® operation and the low drop internal
    power switch result in high efficiency over a broad range
    of load current. Wide Input Voltage Range: 3.2V to 34V
    Micropower Operation: IQ = 12μA
    5V at 250mA from 6.5V to 34V Input (LT1934)
    5V at 60mA from 6.5V to 34V Input (LT1934-1)
    3.3V at 250mA from 4.5V to 34V Input (LT1934)
    3.3V at 60mA from 4.5V to 34V Input (LT1934-1)
    Low Shutdown Current: <1μA
    Low VCESAT Switch: 200mV at 300mA
    Low Profile (1mm) SOT-23 (ThinSOT™) and
    (2mm × 3mm × 0.8mm) 6-Pin DFN Package APPLICATIONS n The LT1934 provides up to 300mA of output current. The ...
