ELM99xxxA ELM99xxxA
■ GENERAL DESCRIPTION
LOW SATURATION VOLTAGE REGULATOR
ELM99xxxA series is CMOS voltage regulator providing large current. It consists of devices including reference voltage source, error amplifier, low resistance output transistor, short-circuit protection circuit, output voltage setting resistor, chip-enable circuit. Output voltage is fixed internally with high accuracy. ELM99xxxA provides excellent characteristics, such as small input-output voltage difference due to low resistance output transistor, high load stability due to high gain error amplifier. The chip-enable function is available in three selections, no-chip enable function, active-low (“L” active) and active-high (“H” active). The package is SOT-89-3 or SOT-89-5. SOT-89-5 is used for chip enable version.
■ FEATURES
