• Manufacturer Part Number: ncv87706ds50r4g
• Description: Ncv8770 - Low Dropout Regulator With Reset
• Manufacturer: ON Semiconductor

General
duty cycle techniques to maintain junction temperature as
close as possible to ambient temperature.
Output voltage
temperature, input voltage and output current values or
specified over Line, Load and Temperature ranges.
Line Regulation
measured for specific output current over operating ambient
temperature range.
Load Regulation
current measured for specific input voltage over operating
ambient temperature range.
Dropout Voltage
output no longer maintains regulation against further
reductions in input voltage. It is measured when the output
drops 100 mV below its nominal value. The junction
temperature, load current, and minimum input supply
requirements affect the dropout level.
Quiescent Current
current (measured through the LDO input pin) and the
output load current.
All measurements are performed using short pulse low

Current Limit and Short Circuit Current Limit
voltage drops below 96% of its nominal value. Short Circuit
Current Limit is output current value measured with output
of the regulator shorted to ground.
PSRR
voltage and input voltage ripple. It is measured in decibels
(dB).
Line Transient Response
response when the input voltage is excited with a given
slope.
Load Transient Response
response when the output current is excited with a given
slope between low−load and high−load conditions.
Thermal Protection
the integrated circuit in the event that the maximum junction
temperature is exceeded. When activated at typically 175°C,
the regulator turns off. This feature is provided to prevent
failures from accidental overheating.
Maximum Package Power Dissipation
dissipation for particular package or power dissipation at
which the junction temperature reaches its maximum
operating value, whichever is lower.
Current Limit is value of output current by which output
Power Supply Rejection Ratio is defined as ratio of output
