- Wide 2.6 V to 12 V input voltage range (16 V absolute maximum) accommodating diverse power source rails in embedded systems
- Compact 10-DFN 3x3 mm no-lead package minimizes PCB footprint for space-constrained IoT, wearable, and battery-powered designs
Applications
The NCP3335AMN330R2G is used in battery-powered IoT devices, portable instrumentation, and microcontroller power supply rails requiring a clean 3.3 V at up to 500 mA from higher input voltages. Its 340 mV maximum dropout allows operation from lithium-ion cells discharging down to approximately 3.7 V, extending battery run time. The 3x3 mm DFN package is well suited for compact PCBA designs in Bluetooth modules, GPS trackers, and wearable health monitors.

Frequently Asked Questions
What is the minimum input voltage and dropout voltage for the NCP3335AMN330R2G at 500 mA output?
The NCP3335AMN330R2G requires a minimum input voltage of 2.6 V and has a maximum dropout voltage of 340 mV at 500 mA load. This means the input must stay above approximately 3.64 V to maintain a stable 3.3 V output at full rated current, making it compatible with lithium-ion battery rails above 3.7 V nominal.
How does the NCP3335AMN330R2G perform in a 5 V to 3.3 V conversion for a microcontroller rail?
In a 5 V to 3.3 V application, the NCP3335AMN330R2G delivers 500 mA with 1.7 V of headroom, well above its 340 mV dropout threshold. Power dissipation at full load equals 1.7 V times 500 mA equaling 850 mW, so adequate thermal management via the 3x3 mm DFN exposed pad is needed to maintain junction temperature within the rated range.
When would NCP3335AMN330R2G be preferred over an NCP3335 variant with adjustable output?
The fixed 3.3 V NCP3335AMN330R2G eliminates external resistor divider components needed for adjustable variants, reducing BOM count by at least 2 resistors and lowering layout complexity. This fixed-output version is ideal when 3.3 V is the only required rail and PCB area or cost is constrained, whereas the adjustable variant suits designs needing a non-standard output voltage between 1.5 V and 5 V.
