NCV8535
Ultra High Accuracy, Low Iq,
500 mA Low Dropout
Regulator with Enable
The NCV8535 is a high performance, low dropout regulator. With
accuracy of 0.9% over line and load and ultra−low quiescent current
and noise it encompasses all of the necessary features required by
today’s consumer electronics. This unique device is guaranteed to be
stable without a minimum load current requirement and stable with
any type of capacitor as small as 1.0 mF. The NCV8535 also comes
equipped with sense and noise reduction pins to increase the overall
utility of the device. The NCV8535 offers reverse bias protection.
Features
High Accuracy Over Line and Load (0.9% at 25C)
Ultra−Low Dropout Voltage at Full Load (260 mV typ.)
No Minimum Output Current Required for Stability
Low Noise (31 mVrms w/10 nF Cnr and 51 mVrms w/out Cnr)
Low Shutdown Current (0.07 mA)
Reverse Bias Protected
2.9 V to 12 V Supply Range
Thermal Shutdown Protection
Current Limitation
Requires Only 1.0 mF Output Capacitance for Stability
Stable with Any Type of Capacitor (including MLCC)
