    SGM2031

    Low Power, Low Dropout, RF Linear Regulator
     
    Low Power, Low Dropout, RF Linear Regulator
    GENERAL DESCRIPTION

    The SGM2031 series low-power, low-dropout, CMOS linear voltage regulators operate from a 2.5V to 5.5V input voltage in an ultra small package. They are the perfect choice for low voltage, low power applications. A low ground current makes this part attractive for battery operated power systems. The SGM2031 series also offer ultra low dropout voltage to prolong battery life in portable electronics. Systems requiring a quiet voltage source, such as RF applications, will benefit from the SGM2031 series’ low output noise and high PSRR.

    Other features include a 10nA logic-controlled shutdown mode, foldback current limit and thermal shut-down protection.

    The SGM2031 is available in a Green UTDFN-1×1-4L package. It operates over an ambient temperature range of -40 to +85.
