ELM ELM89251BC-N Cmos 300ma ldo voltage regulator Datasheet

ELM89xxxBC CMOS 300mA LDO Voltage regulator
■General description
ELM89xxxBC is CMOS LDO voltage regulator. There are 3 types of CE selection for ELM89 series: non-chip
enable function, “L”active and “H”active. Thermal shutdown protective function and short circuit current limiter
are included in the IC. The standard output voltages are 1.2V, 1.8.V, 2.5V, 3.0V, 3.3V, 5.0V; ELM89 series can
also be designed as semi-custom IC within the range of 0.8V to 5.0V by 0.1V step.
