Low
Dropout Linear Regulator
with Reset and Reset Delay
The NCV8675 is a precision 5.0 V and 3.3 V fixed output, low
dropout integrated voltage regulator with an output current capability
of 350 mA. Careful management of light load current consumption,
combined with a low leakage process, achieve a typical quiescent
ground current of 34 mA.
NCV8675 is pin for pin compatible with NCV4275 and it could
replace this part when very low quiescent current is required.
The output voltage is accurate within ±2.0% for D
2
PAK−5 package
and ±2.5% for DPAK−5 package, and maximum dropout voltage is
600 mV at full rated load current.
It is internally protected against input transients, input supply
reversal, output overcurrent faults, and excess die temperature. No
external components are required to enable these features.
Features
• 5 V and 3.3 V Fixed Output (2.5 V Version Available Upon Request)
• ±2.0% or ±2.5% Output Accuracy, Over Full Temperature Range
• 34 mA Typical Quiescent Current at I
out
= 100 mA, 50 mA Maximum
up to 85°C
• 600 mV Maximum Dropout Voltage at 350 mA Load Current
• Wide Input Voltage Operating Range of 4.5 V to 45 V
• Internal Fault Protection
♦ −42 V Reverse Voltage
♦ Short Circuit/Overcurrent
♦ Thermal Overload
• AEC−Q100 Qualified
• EMC Compliant
• NCV Prefix for Automotive and Other Applications Requiring Site
and Control Changes
• These are Pb−Free Devices
