-
-
-
The SGM2013 low-power, low-dropout, CMOS linear
voltage regulators operate from a 2.5V to 5.5V input and
deliver up to 300mA. They are perfect choice for low voltage,
low power applications. An ultra low ground current (200
µA
at 300mA output) makes them attractive for battery
operated power systems. The SGM2013 series also offer
ultra low dropout voltage (300mV at 300mA output) to
prolong battery life in portable electronics
The output voltage is preset to voltages in the range of 1.8V
to 3.3V. Other features include
foldback current limit
and
thermal shut-down protection.
SGM2013 come in 3-pin SOT23 and 3-pin SOT89 package.
