The NCP5304DR2G from ON Semiconductor is a low dropout linear regulator capable of supplying up to 300mA at a fixed 4.2V output with an ultra-low quiescent current of 140μA.

Key Features:

• 4.2V fixed output voltage
• Wide 1.7V to 5.5V input voltage range
• Continuous current of 300mA at 4.2V output
• Low 140μA typical quiescent current
• Small SOT-23-5 package footprint

Common Applications:

• Battery powered sensors and wearable devices
• IoT edge nodes and portable electronics
• Auxiliary supplies for low power microcontrollers

Benefits Include:

• Maximizes battery lifetime with low quiescent draw
• Simplifies design with fixed 4.2V output
• Tiny size saves board space for compact solutions

Well-suited for applications where extended runtime and very low idle power consumption are important requirements.

In summary, the NCP5304DR2G provides industry-leading 4.2V regulation with best-in-class ultra-low quiescent current efficiency.
