SG2010
GENERAL DESCRIPTION
The SG2010 low-power, low-dropout, CMOS linear voltage
regulator operates from 2.5V to 5.5V input and delivers up
to 150mA. It is the perfect choice for low voltage, low
power applications. An ultra low ground current (100
µA
at 150mA output ) makes this part attractive for battery
operated power systems. The SG2010 series also offers
ultra low dropout voltage (105mV at 150mA output) to
prolong battery life in portable electronics.
The output voltage is preset to voltages in the range of 1.5V
to 5.0V. Other features include
foldback current limit
and
thermal shut-down protection.
SG2010 comes in 3-pin SOT23 package and 3-pin SOT89
package.
