DESCRIPTION

The SGM2018 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.

Output capacitor as small as 0.1μF can be used. The SGM2018 series operate with an ultra-low current consumption and only 1μA typical current is consumed to prolong the battery run-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 leakage current is 0.4μA (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 SGM2018 series. The SGM2018 series feature ultra-low current consumption and come in small packages, making them most suitable for portable equipment.

The SGM2018 series is available in Green SOT-23-5 and UTDFN-1×1-4AL packages. It operates over an operating temperature range of -40℃ to +85℃.
