onsemi NCP163AMX180TBG: High-Performance, Low-Quiescent Current Dual-Output Linear Regulator

In the realm of power management, efficiency and reliability are paramount. The onsemi NCP163AMX180TBG stands out as a premier dual-output linear regulator engineered to meet the rigorous demands of modern electronic applications. This device integrates two independent 180 mA linear regulators into a single, compact package, providing a streamlined solution for powering multiple low-voltage rails with exceptional performance and minimal board space.

A defining characteristic of the NCP163 is its remarkably low quiescent current, typically drawing only 28 µA per regulator when lightly loaded. This feature is critical for battery-powered and always-on applications, such as those found in the Internet of Things (IoT), wearables, and portable medical devices, where extending operational life is a primary design goal. The low ground current is maintained across a wide range of output currents and input voltages, ensuring consistent efficiency.

The regulator boasts an impressive power supply rejection ratio (PSRR), exceeding 70 dB at 1 kHz. This high PSRR effectively attenuates unwanted noise and ripple from the input supply, resulting in a clean, stable output voltage. This is essential for powering noise-sensitive components like analog sensors, RF transceivers, and precision microcontrollers, ensuring their optimal performance and signal integrity.

Designed for robustness, the NCP163 operates over a wide input voltage range from 2.4 V to 5.5 V, making it compatible with a variety of power sources, including lithium-ion batteries, 3.3 V system rails, and 5 V bus supplies. Each regulator features independent enable pins for flexible power sequencing and management. Furthermore, the device is fortified with comprehensive protection features, including current limiting and thermal shutdown, which safeguard both the IC and the downstream circuitry under fault conditions.

Housed in a space-saving 8-pin XDFN package, the NCP163AMX180TBG offers a superior blend of performance, efficiency, and integration, simplifying power supply design for space-constrained applications.
