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
Maximum output current High accuracy of output voltage Small input-output voltage differential Low stand-by current consumption High load stability High input stability Output voltage range Short-circuit current limiter Chip-enable pin available : 300mA (Intenal current limiter operates in case load current exceeds 300mA.) : 2.0% : TYP. 140mV (ELM9930xA IOUT=40mA) : TYP. 0.1 A (ELM99xx3A) : TYP. 5mV (1mA Iout 100mA) : TYP. 0.15%/V (ELM9930xA IOUT=40mA) : 2.0V 6.0V ( 0.1V steps ) : TYP. 70mA (VOUT=0V) : "L"active ELM99xx2A, "H"active ELM99xx3A Palmtops cameras and video recorders Battery-operated devices
