Dropout, Linear Regulators

SG2012

GENERAL DESCRIPTION

FEATURES

- Ultra-Low Dropout Voltage:

280mV at 400mA output

- Low 80µA No-Load Supply Current

- Low 120µA Operating Supply Current

at 400mA Output

- Thermal-Overload Protection

- Output Current Limit

- Preset Output Voltages (±1.8% Accuracy)

- Output Voltage:

The SG2012 low-power, low-dropout, CMOS linear voltage

regulators operate from a 2.5V to 5.5V input and deliver up

to 400mA. They are perfect choice for low voltage, low

power applications. An ultra low ground current (120µA at

400mA output) makes them attractive for battery operated

power systems. The SG2012 series also offer ultra low

dropout voltage (280mV at 400mA output) to prolong

battery life in portable electronics.

The output voltage is preset to voltages in the range of 1.5V

to 4.5V. 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, and 3.3V

SG2012 comes in 3-pin SOT223 package.
