    The LP5990 regulator is designed to meet the requirements of portable, battery-powered systems providing an accurate output voltage, low noise and low quiescent current.

    The LP5990 will provide a 1.8V output from a low input voltage of 2.2V and can provide 200mA to an external load.

    When switched into shutdown mode via a logic signal at the enable pin, the power consumption is reduced to virtually

    zero.

    Fast shut-down is achieved by the push pull architecture.

    The LP5990 is designed to be stable with space saving 0402 ceramic capacitors as small as 1µF, this gives an overall solution size of < 2.5mm 2.

    Performance is specified for a -40°C to 125°C junction temperature range.

    The device is available in micro SMD Package (0.4mm pitch) and is available with 1.2V,1.3V,1.8V,2.8V,3.0V,3.3V and 3.6V outputs.Lower voltage options down to 0.8V are available on request. For all other output voltage options please contact your local NSC sales office.
