SGM2015
Low Power, Low Dropout,
250mA, RF - Linear Regulators
GENERAL DESCRIPTION
The SGM2015 series low-power, low-noise, low-dropout,
CMOS linear voltage regulators operate from a 2.5V to 5.5V
input and deliver up to 250mA. They are the perfect choice
for low voltage, low power applications. An ultra low
www.DataShgereotu4Un.dcocmurrent（160µA at 250mA output ) makes these part
attractive for battery operated power systems. The
SGM2015 series also offer ultra low dropout voltage
(250mV at 250mA output) to prolong battery life in
portable electronics. Systems requiring a quiet voltage
source, such as RF applications, will benefit from the
SGM2015 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 3.3V. Other features include a 10nA logic-controlled
shutdown mode, foldback current limit and thermal shut-
down protection.
Devices come in 5-pin SOT23 package.
