    SGM2035C

    500mA, Ultra Low Dropout, Low Power, RF Linear Regulator
     
    500mA, Ultra Low Dropout, Low Power, RF Linear Regulator
    GENERAL DESCRIPTION

    The SGM2035C is a low-power, low-noise, low-dropout, CMOS linear voltage regulator that operates from a 2.5V to 5.5V input voltage.

    The SGM2035C is the perfect choice for low voltage, low power applications. A low ground current makes this part attractive for battery operated power systems. The SGM2035C also offers 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 SGM2035C’s ultra low output noise (30μVRMS) and high PSRR. An external noise bypass capacitor connected to the device’s BP pin can further reduce the noise level.

    Other features include a 110kΩ pull down resistor at EN pin, current limit and thermal shutdown protection.

    The SGM2035C is available in Green UTDFN-1.6×1.6-6L and TDFN-2×2-6L packages. It operates over an ambient temperature range of -40 to +85.
