- Output Voltage:
The SG2011 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 (110µA at
300mA output) makes them attractive for battery operated
power systems. The SG2011 series also offer ultra low
dropout voltage (210mV at 300mA 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.
Available in Fixed Outputs of 1.5V, 1.8V, 2.5V, 2.8V,
3.0V, 3.3V, and 3.6V
SG2011 comes in 3-pin SOT23 and 3-pin SOT89 packages.
