NCV4269CD250R2G: A 150 mA Low-Quiescent Current LDO Voltage Regulator from onsemi

In the realm of power management for modern electronic systems, efficiency and reliability are paramount. The NCV4269CD250R2G from onsemi stands out as a robust and highly efficient 150 mA low-dropout (LDO) linear voltage regulator designed to meet the stringent demands of automotive and industrial applications. This device exemplifies advanced power management by providing a stable and clean output voltage while consuming minimal power itself, making it an ideal choice for battery-powered and always-on systems.

A key feature of this LDO is its extremely low quiescent current, typically just 19 µA under light load conditions. This characteristic is crucial for applications where power conservation is critical, such as in continuous battery-operated devices found in telematics, infotainment systems, and various sensor modules. By minimizing the current drawn when regulating, the NCV4269CD250R2G significantly extends battery life without compromising performance.

The regulator offers a fixed 2.5V output voltage with high accuracy, capable of delivering up to 150 mA of output current. It operates with a very low dropout voltage, ensuring regulation is maintained even when the input voltage is only slightly above the output level. This is particularly valuable in automotive environments where voltage rails can experience significant fluctuations.

Designed for resilience, the NCV4269CD250R2G incorporates a suite of comprehensive protection features. These include current limiting to safeguard against short circuits, thermal shutdown to prevent damage from overheating, and reverse battery protection (-18 V) for enhanced durability in harsh electrical environments. Its ability to handle input voltages up to 45 V further underscores its suitability for automotive load-dump scenarios.

Housed in a space-saving DFN5 package, the device offers excellent thermal performance and is ideal for compact PCB designs. Its high level of integration and reliability makes it a preferred solution for powering microcontrollers, sensors, and other critical low-power components.

ICGOOODFIND: The onsemi NCV4269CD250R2G is a superior LDO regulator that masterfully balances ultra-low power consumption with robust performance, making it an exceptional choice for power-sensitive automotive and industrial applications.
