  • The A7985A is a step-down switching regulator with a 2.5 A (minimum) current limited embedded power MOSFET, so it is able to deliver up to 2 A current to the load depending on the application conditions.

    The input voltage can range from 4.5 V to 38 V, while the output voltage can be set starting from 0.6 V to VIN.
    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 HSOP8 package with exposed pad allows the reduction of Rth(JA) down to 40 °C/W.

    Key Features

    • AEC-Q100 qualified (see PPAP for more details)
    • 2 A DC output current
    • 4.5 V to 38 V input voltage
    • Output voltage adjustable from 0.6 V
    • 250 kHz switching frequency, programmable up to 1 MHz
    • Internal soft-start and enable
    • Low dropout operation: 100% duty cycle
    • Voltage feed-forward
    • Zero load current operation
    • Overcurrent and thermal protection
    • HSOP8 package
