ELM98xxxA VOLTAGE REGULATOR  
■ GENERAL DESCRIPTION  
ELM98xxxA Series is a CMOS Voltage Regulator. It consists of reference voltage, error amplifier, short-  
protected 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  
: ± 2.0%  
・Load stability  
: TYP. 10mV (1mA ≦ IOUT ≦ 50mA)  
: TYP. 0.1%/V at IOUT=50mA  
: ± 100ppm/℃  
・Input stability  
・ Output voltage temperature coefficient  
・ Very low power operation  
・ Very small package  
: TYP. 4.0 μ A (ELM9830xA)  
: SOT-89, SOT-23  
■ APPLICATION  
・ Battery-operated devices  
・ Palmtops  
・ Cameras and Video recorders  
・ Reference voltage sources
