Low Power, Low Dropout,
SGM2008
300mA, RF-Linear Regulators
GENERAL DESCRIPTION
FEATURES
- Low Output Noise: 30µVRMS typ(10Hz to 100KHz)
- Ultra-Low Dropout Voltage:
The SGM2008/A series low-power, low-noise, low-dropout,
CMOS linear voltage regulators operate from a 2.5V to 5.5V
input and deliver up to 300mA. They are the perfect choice
for low voltage, low power applications. An ultra low
ground current（200µA at 300mA output ) makes these part
attractive for battery operated power systems. The
SGM2008/A series also offer ultra low dropout voltage
(300mV at 300mA output) to prolong battery life in
portable electronics. Systems requiring a quiet voltage
source, such as RF applications, will benefit from the
SGM2008/A series’ 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.
