    1.375V, 1.5MHz, 300mA
    Synchronous Step-Down
    Regulators in ThinSOT U FEATURES DESCRIPTIO ■ The LTC ®3405A-1.375 is a high efficiency monolithic
    synchronous buck regulator using a constant frequency,
    current mode architecture. Supply current during operation is only 20µA and drops to <1µA in shutdown. The 2.5V
    to 5.5V input voltage range makes the LTC3405A-1.375
    ideally suited for single Li-Ion battery-powered applications. 100% duty cycle provides low dropout operation,
    extending battery life in portable systems. ■










    ■ High Efficiency: Up to 90%
    Very Low Quiescent Current: Only 20µA
    During Operation
    300mA Output Current at VIN = 3V ...
