ELM98xxxxCCMOS Voltage regulator
ELM98xxxxC is CMOS voltage regulator, which mainly consists of reference voltage source, error amplifier, short-protected control transistor, thermal protection circuit, output voltage setting resistors. The standard output voltages are 1.8V, 3.3V, 5.0V, 12V; these output voltages are fixed internally with high accuracy. ELM98 series can also be made as semi-custom IC within the range of 1.2V to 15.0V by 0.1V step.
