ELM99xxxxxCCMOS middle current voltage regulator

ELM99xxxxxC is CMOS middle current voltage regulator which consists of reference voltage source, error amplifier, low resistance output transistor, short-circuit protection circuit, thermal protection circuit, output voltage setting resisters and chip-enable circuit. ELM99 series is characterized with small input/output voltage difference (with its low resistance output transistor) and high load stability (with its high gain error amplifier). There are 3 types of CE selection of ELM99 series: non-chip enable function, “L” active and “H” active. The standard output voltages are 3.3V, 5.0V; these output voltages are fixed internally with high accuracy. ELM99 series can also be made as semi-custom IC within the range of 1.5V to 15.0V by 0.1V step.
