■General description
ELM84xxxxA is CMOS voltage regulator which is characterized with high current 1.2A and low dropout (45mV
at Vout=3.3V and Iout=300mA). There are 2 types of CE selection of ELM84 series: non-chip enable function
and “H” active. The standard output voltages are 1.2V, 1.8V, 3.3V, 5.0V. ELM84 series can also be made as
semi-custom IC within the range of 0.8V to 5.0V by 0.1V step. This series includes short circuit current limiter,
inrush current limiter and thermal shutdown circuit. Ceramic capacitors with low ESR can be used as input and
output ones. Output capacitor discharge function is also available as semi-custom.
