ELM98xxxA VOLTAGE REGULATOR ELM98xxxA
■ GENERAL DESCRIPTION
ELM98xxxA Series is a CMOS Voltage Regulator. It consists of reference voltage, error amplifier, shortprotected control transistor, output voltage setting resistor, and so on. Output voltage is fixed internally with high accuracy. Two package types are available, SOT-89 and SOT-23.
■ FEATURES
・ High accuracy ・ Load stability ・ Input stability ・ Output voltage temperature coefficient ・ Very low power operation ・ Very small package : ± 2.0% : TYP. 10mV (1mA ≦ IOUT ≦ 50mA) : TYP. 0.1%/V at IOUT=50mA : ± 100ppm/℃ : TYP. 4.0 μ A (ELM9830xA) : SOT-89, SOT-23
■ APPLICATION
・ Battery-operated devices ・ Palmtops ・ Cameras and Video recorders ・ Reference voltage sources
