ELM99xxxA LOW SATURATION VOLTAGE REGULATOR

■ GENERAL DESCRIPTION

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

: 300mA (Intenal current limiter operates in case load

current exceeds 300mA.)

・ High accuracy of output voltage

・Small input-output voltage differential

・Low stand-by current consumption

・High load stability

: ± 2.0%

: TYP. 140mV (ELM9930xA IOUT=40mA)

: TYP. 0.1 μ A (ELM99xx3A)

: TYP. 5mV (1mA ≦ Iout ≦ 100mA)

: TYP. 0.15%/V (ELM9930xA IOUT=40mA)

: 2.0V～ 6.0V ( 0.1V steps )

・High input stability

・ Output voltage range

・Short-circuit current limiter

・Chip-enable pin available

: TYP. 70mA (VOUT=0V)

: “L”active ELM99xx2A, “H”active ELM99xx3A

■ APPLICATION
