SGM2006/A
GENERAL DESCRIPTION
The SGM2006/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 150mA. They are the perfect choice
for low voltage, low power applications. An ultra low
ground current ( 150
µA
at 150mA output ) makes these
part attractive for battery operated power systems. The
SGM2006/A 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
SGM2006/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.
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 5-pin SOT23 package.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress
ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational
sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

FUNCTION
Regulator Input. Supply voltage can range from 2.5V to 5.5V. Bypass with a 1µF capacitor to GND.
Ground.
Shutdown Input. A logic low reduces the supply current to 10nA. Connect to IN for normal operation.
Reference-Noise Bypass(fixed voltage version only). Bypass with a low-leakage 0.01µF ceramic capacitor for
reduced noise at the output.
Adjustable voltage version only—this is used to set the output voltage of the device.
