  • Description

    The L78L00 series of three-terminal positive regulators, including the L78L33ACUTR model, are designed with internal current limiting and thermal shutdown features. These regulators are highly durable and can deliver up to 100 mA of output current with the proper heat-sink. They are commonly used as fixed voltage regulators in various applications, such as local or on-card regulation, to eliminate noise and distribution issues associated with single-point regulation. Additionally, they can be combined with power pass elements to create high-current voltage regulators. Compared to a Zener diode/resistor combination, the L78L00 series offers a significant improvement in output impedance, lower quiescent current, and reduced noise.

    Specifications and features

    • Output current up to 100 mA
    • Output voltages available: 3.3V, 5V, 6V, 8V, 9V, 10V, 12V, 15V, 18V, 20V, 24V
    • Thermal overload protection
    • Short circuit protection
    • No external components required
    • Available in either ±5% (AC) or ±10% (C) selection

    Application Scenarios

    The L78L33ACUTR model of the L78L00 series is suitable for various applications, including but not limited to:

    • Local or on-card voltage regulation
    • Noise elimination in electronic systems
    • Power supply for low-current devices
