The NCP5332ADWR2 is a 3V/5V dual mode, low dropout (LDO) regulator, aimed at achieving lowest possible power dissipation with low part count for variety of RF and analog loads at Lithium-ion platform. This device targets wide range of space limited, low power applications like USB power port and portable audio docking stations and phones with its surface mount package.

This device is particularly suited for applications which require flexibility, and typical applications include RF transceivers, audio power amplifiers, and low power processor cores. This device is designed to regulate two different loads with two separate output voltages (3.3V and 5V) using a single Chip Select pin. The NCP5332ADWR2 can also be used to regulate negative and positive voltages when used in a synchronous buck-boost mode.

At the heart of the NCP5332ADWR2 is the integrated power stage featuring two low-on-resistance NMOSFETs. This allows the device to provide up to 9A of continuous output current capability and a maximum peak current of 15A. The NCP5332ADWR2 also includes protection features to provide reliable protection against overvoltage, overcurrent, undervoltage, and overtemperature conditions.

The NCP5332ADWR2 also features a low power consumption design that reaches as low as 10 ᦓᦓA quiescent current at 3.3V mode and 5 ᦓᦓA quiescent current at 5V mode. This helps to maintain an extremely efficient and low power pplication for any application that requires an extra level of control.

The working principle of the NCP5332ADWR2 is fairly simple and efficient. The device is a dual-mode low dropout voltage regulator that is capable of regulating both positive and negative voltages. The voltage regulator is designed to regulate two separate loads with two different output voltages. The Chip Select pin is used to enable or disable the two separate outputs. When enabled, the two outputs will be regulated to the respective output voltages. This allows the device to achieve lower power dissipation with low part count compared to traditional linear regulators.

The NCP5332ADWR2 is designed for a wide range of applications, including USB Power Ports, portable audio docking stations and phones, RF transceivers, audio power amplifiers, and low-power processor cores. It is suitable for space-limited and low-power applications that require low part count and flexibility. This device features low power dissipation with low quiescent current and wide output envelope to meet the needs of various applications that demand efficient power control.
