• Description: 150 mA CMOS Low Noise Low-Dropout Voltage Regulator
• Manufacturer: ON

Load Regulation
current at a constant temperature.
Dropout Voltage
no longer maintains regulation against further reductions in
input voltage. Measured when the output drops 2% below its
nominal. The junction temperature, load current, and
minimum input supply requirements affect the dropout level.
Output Noise Voltage
specified frequency range. Input voltage and output load
current are kept constant during the measurement. Results

Quiescent Current
regulator operates without a load on its output: internal IC
operation, bias, etc. When the LDO becomes loaded, this
term is called the Ground current. It is actually the difference
between the input current (measured through the LDO input
pin) and the output current.

Line Regulation
The measurement is made under conditions of low
dissipation or by using pulse technique such that the average
chip temperature is not significantly affected.
Line Transient Response
is excited with a given slope.
Thermal Protection
the integrated circuit in the event that the maximum junction
temperature is exceeded. When activated at typically 160 C,
the regulator turns off. This feature is provided to prevent
failures from accidental overheating.
Maximum Package Power Dissipation
temperature reaches its maximum operating value, i.e.
125 C.
The change in output voltage for a change in input voltage.
Typical over and undershoot response when input voltage
Internal thermal shutdown circuitry is provided to protect
