The SGM2040 series are positive voltage regulators with ultra low current consumption, low dropout voltage, high-accuracy output voltage and 250mA output current, developed in CMOS technology. Input and output capacitors as small as 0.1μF can be used. The SGM2040 series operate with an ultra low current consumption, only 1μA typical current is consumed to prolong the battery used time.

The built-in low on-resistance transistor realizes low dropout voltage and a large output current. A built-in over-current protection circuit prevents the load current from exceeding the current capacity of the output transistor. Reverse current is less than 0.2μA (TYP) when VOUT > VIN. Compared with voltage regulators using a conventional CMOS technology, more types of capacitors, including small input and output capacitors, can be used with the SGM2040 series. The SGM2040 series feature ultra low current consumption and come in small packages, making them most suitable for portable equipment.

The SGM2040 is available in Green UTDFN-1×1-4AL and SOT-23-5 packages. It operates over an ambient temperature range of -40℃ to +85℃
