GENERAL DESCRIPTION

The SGM2074 is a low noise, low dropout, bias rail

CMOS voltage regulator. It is capable of supplying

500mA output current with typical VIN dropout voltage of

only 125mV. The operating input voltage range is from

0.8V to 5.5V and bias supply voltage range is from 2.5V

to 5.5V. The output voltage range is from 0.8V to 3.6V.

Other features include 1.2V logic-controlled shutdown

mode, short-circuit current limit and thermal shutdown

protection. The SGM2074 has automatic discharge

function to quickly discharge VOUT in the disabled status.

The SGM2074 is suitable for applications which need

low noise, fast load transient response and low IQ

consumption, such as battery-powered equipment and

smartphones, etc.

The SGM2074 is available in Green SOT-23-5, SOT-23-6

and XTDFN-1.2×1.2-6L packages. It operates over an

operating temperature range of -40℃ to +125℃.
