ELM99xxxxxC is CMOS middle current voltage regulator which consists of reference voltage source, error

amplifier, low resistance output transistor, short-circuit protection circuit, thermal protection circuit, output

voltage setting resisters and chip-enable circuit. ELM99 series is characterized with small input/output voltage

difference (with its low resistance output transistor) and high load stability (with its high gain error amplifier).

There are 3 types of CE selection of ELM99 series: non-chip enable function, “L” active and “H” active. The

standard output voltages are 3.3V, 5.0V; these output voltages are fixed internally with high accuracy. ELM99

series can also be made as semi-custom IC within the range of 1.5V to 15.0V by 0.1V step.

• Output voltage range

: 1.5V to 15.0V (by 0.1V)

• Max. output current

• Stand-by current consumption : Max.0.1μA(ELM99033xxC)

• Input stability

: Typ.0.1%/V(Iout=40mA)

• Load stability

: Typ.5mV(1mA≤Iout≤100mA)

• Accuracy of output voltage

: ±2.0%

• Protection circuit

: Thermal protection, Short protection

• Package

: SOT-89, SOT-89-5, SOT-23, SOT-25
