■General description
ELM84xxxxxA 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.
