GENERAL DESCRIPTION

The SGM2005 series low-power, low-noise, low-dropout, CMOS linear voltage regulators operate from a 2.5V to 5.5V input and deliver up to 150mA. They are the perfect choice for low voltage, low power applications. An ultra low ground current ( 150µA at 150mA output ) makes these parts attractive for battery operated power systems.

FEATURES

- Low Output Noise: 30µVRMS typ(10Hz to 100KHz)

- Ultra-Low Dropout Voltage: 150mV at 150mA output

- Low 77µA No-Load Supply Current

- Low 150µA Operating Supply Current at 150mA Output

- High PSRR: 73dB at 1KHz
