NCP4623
150 mA, Wide Input Voltage
Range, Low Dropout
Regulator
The NCP4623 is a CMOS Linear Voltage Regulator designed for
wide input voltage range. The maximum operating input voltage is up
to 24 V with a minimum voltage starting from 2 V. The Chip Enable
(CE) pin allows the device to lower standby current to 0.1 mA typ. The
NCP4623 features many protections for any current or thermal
sensitive devices with current foldback protection, thermal shutdown
protection, and peak and short current protection. This device is
available in adjustable and fixed voltage output in 0.1 V steps. They
are available in very thin XDFN6 1.6x1.6x0.4 mm in size and the very
popular SOT235 and SOT895 packages. Please contact your local
sales office for additional output voltage options.
Features
Maximum Operating Input Voltage: 24 V
Output Voltage Range: 2.5 V to 12.0 V (available in 0.1 V steps)
2.5 V to 24.0 V (adjustable version)
Output Voltage Accuracy: ±2.0%
Supply Current: 5 mA
Stable with Ceramic Capacitors: 1 mF or more
Current Fold Back Protection
Peak and Short Current Protection
Thermal Shutdown Protection
Available in XDFN6 1.6 x 1.6 mm, SOT235, SOT895 Packages
