Addressing these needs, the NCV4264D50R2G from onsemi stands out as a robust 50 V, 150 mA low-dropout (LDO) linear regulator engineered for superior performance. This device integrates critical protection features and minimal power consumption, making it an ideal solution for always-on systems requiring stable voltage regulation.

Key Features and Benefits

The NCV4264D50R2G offers a fixed 5.0 V output with an impressive input voltage range of up to 50 V, providing ample headroom for load-dump and transient conditions common in automotive environments. Its low quiescent current of just 30 µA (typical) significantly reduces power loss during standby mode, extending battery life in applications such as infotainment systems, instrument clusters, and telematics. Additionally, the regulator incorporates over-current protection (OCP) and thermal shutdown mechanisms, safeguarding both the IC and the downstream circuitry from fault conditions. The device’s high PSRR (Power Supply Rejection Ratio) and low output noise ensure clean, stable power delivery to sensitive components.

Design Advantages and Applications

Designed for resilience, the NCV4264D50R2G operates over a wide temperature range (-40°C to +150°C), ensuring reliability in extreme conditions. Its minimal external component count simplifies PCB layout and reduces overall system cost. The regulator is AEC-Q100 qualified, emphasizing its suitability for automotive electronics. Key applications include powering microcontrollers, sensors, and CAN bus interfaces, where consistent voltage regulation is critical.
