  • The L5981 is a step-down switching regulator with a 1.5 A (min.) current limited embedded Power MOSFET, so it is able to deliver in excess of 1 A DC current to the load depending on the application condition.

    The input voltage can range from 2.9 V to 18 V, while the output voltage can be set starting from 0.6 V to VIN. Having a minimum input voltage of 2.9 V, the device is suitable also for a 3.3 V bus.
    Requiring a minimum set of external components, the device includes an internal 250 kHz switching frequency oscillator that can be externally adjusted up to 1 MHz.
    The VFQFPN8 package with an exposed pad allows reducing the RthJA down to approximately 60 °C/W.

    主要特性

    • 1 A DC output current
    • 2.9 V to 18 V input voltage
    • Output voltage adjustable from 0.6 V
    • 250 kHz switching frequency, programmable up to 1 MHz
    • Internal soft-start and inhibit
    • Low dropout operation: 100% duty cycle
    • Voltage feedforward
    • Zero load current operation
    • Overcurrent and thermal protection
    • VFQFPN8 3 mm x 3 mm package
