ELM81xxxxA 1μA Low power consumption CMOS 150mA V/R
ELM81xxxxA is CMOS voltage regulator which is characterized with low current consumption and low dropout. ELM81 series provides high output current of 150mA while the consumption current is comparatively low, which is Typ.1.0μA. There are 2 types of CE selection for ELM81 series: non-chip enable function and “H” active. The standard output voltages are 1.8V, 2.5V, 3.0V, 3.3V, 5.0V; ELM81 series can also be designed as a semi-custom IC within the range of 1.5V to 5.0V by 0.1V step. Thermal shutdown protection and short-circuit current limiter are included in the IC. Ceramic condenser with low ESR can be used as input and output ones.
