    The S-1111/1121 Series is a positive voltage regulator with a low dropout voltage, high output voltage
    accuracy, and low current consumption developed based on CMOS technology.
    A built-in low on-resistance transistor provides a low dropout voltage and large output current, and a built-
    in overcurrent protector prevents the load current from exceeding the current capacitance of the output
    transistor. An ON/OFF circuit ensures a long battery life, and a small SOT-23-5 package realize high-
    density mounting. The lineup includes the S-1111 and S-1121 Series, which differ in pin configuration.
    Features
    Output voltage:
    1.5 V to 5.5 V, selectable in 0.1 V steps.

    *1
    Built-in ON/OFF circuit:
    Ensures long battery life.
    High ripple rejection:
    70 dB typ. (at 1.0 kHz)
    Built-in overcurrent protector: Overcurrent of output transistor can be restricted.
    Lead-free, Sn 100%, halogen-free*2
    *1. Attention should be paid to the power dissipation of the package when the output current is large.
    *2. Refer to “
    Product Name Structure” for details.
