    ■ DESCRIPTIO The LTC®3801/LTC3801B are constant frequency current mode step-down DC/DC controllers in a low profile
    (1mm max) 6-lead SOT-23 (ThinSOTTM) package. The
    parts provide excellent AC and DC load and line regulation with ±1.5% output voltage accuracy. The LTC3801
    consumes only 195µA of quiescent current in normal
    operation, dropping to 16µA under no-load conditions. High Efficiency: Up to 94%
    Very Low No-Load Quiescent Current:
    Only 16µA (LTC3801)
    High Output Currents Easily Achieved
    Internal Soft-Start ...
