NCP5662, NCV5662

Low Output Voltage,
Ultra-Fast 2.0 A Low Dropout
Linear Regulator with Enable

The NCP5662/NCV5662 is a high performance, low dropout linear
regulator designed for high power applications that require up to 2.0 A
current. It is offered in both fixed and adjustable output versions. With
output voltages as low as 0.9 V and ultra-fast response times for load
transients, the NCP5662/NCV5662 also provides additional features
such as Enable and Error Flag (for the fixed output version),
increasing the utility of these devices. A thermally robust, 5 pin

D

PAK or DFN8 package, combined with an architecture that offers
low ground current (independent of load), provides for a superior
high-current LDO solution.

Positive Power Supply Input Voltage

Regulated Output Voltage

This pin is connected to the resistor divider network and programs
the output voltage.

An Error Flag is triggered when the output voltage is out of regulation
excluding transient signals that may occur. Requires a pullup resistor
f 100 kW.

No connection. True no connect. PCB runs allowable.
