ELM85xxxxA CMOS 600mA/800mA LDO voltage regulator
■General description
ELM85xxxxA is CMOS voltage regulator which is characterized with high current and low dropout (55mV at
Iout=100mA). There are 2 types of CE selection of ELM85 series: non-chip enable function and “H” active.
The standard output voltages are 3.0V, 3.3V, 5.0V. ELM85 series can also be made as semi-custom IC within
the range of 0.8V to 5.0V by 0.1V step. This series also includes short circuit current limiter and thermal
shutdown circuit. Ceramic capacitors with low ESR can be used as input and output ones.
