SGM2005
Low Power, Low Dropout,
150mA, RF - Linear Regulators
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. The
SGM2005 series also offer ultra low dropout voltage
(150mV at 150mA output) to prolong battery life in
portable electronics. Systems requiring a quiet voltage
source, such as RF applications, will benefit from the
SGM2005 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.
The output voltage is preset to voltages in the range of 1.5V
to 5.0V. Other features include a 10nA logic-controlled
shutdown mode, foldback current limit and thermal shut-
down protection.
Devices come in 6-pin DFN-6 package.
