NCP5006SNT1G

Overview

The NCP5006SNT1G is a low-dropout (LDO) linear voltage regulator manufactured by onsemi, designed for surface-mount applications. It provides a fixed output voltage of 3.3V with a maximum continuous output current capability of 150mA. The device operates within an input voltage range from 1.8V to 6V and features a typical dropout voltage of 2mV at 1mA load. It incorporates an enable pin for power management control. The regulator maintains a quiescent current of approximately 300µA and ensures high line regulation of 10mV and load regulation of 45mV. It is housed in a compact SOT-23-5 package and supports operation across an extended temperature range from -40°C to +125°C.

Feature Summary

• Fixed 3.3V output with 150mA current capacity
• Ultra-low dropout voltage for efficient power usage
• Integrated enable pin for system power control
• High accuracy line and load regulation

Applications

• Portable battery-powered electronic devices
• Embedded systems requiring stable low-voltage rails
• Communication modules needing precise voltage regulation
• Microcontroller power supply circuits

Procurement Notes

Verify the specific suffix 'T1G' confirms tape-and-reel packaging when ordering. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the datasheet revision date against your design timeline to confirm parameter stability. Confirm that the SOT-23-5 footprint matches your PCB layout constraints before finalizing procurement quantities.

Selection Notes

Select this regulator when a fixed 3.3V rail is required with minimal voltage drop under light loads. It is suitable for space-constrained designs due to its small SOT-23-5 package. Consider the 150mA limit for load requirements; higher currents may necessitate alternative packages or parallel configurations. The wide operating temperature range makes it appropriate for industrial or automotive environments where thermal stability is critical.

Part Context

This component belongs to the NCP500 series of low-power LDO regulators from onsemi. The series is characterized by CMOS technology for low quiescent current consumption. The NCP5006 variant specifically offers a fixed 3.3V output, distinguishing it from adjustable or other fixed-voltage options within the same family. It serves as a key power management solution for portable electronics requiring efficient voltage conversion.

Replacement Considerations

Direct substitutes include other NCP500 series parts with compatible output voltages and current ratings, such as NCP500SN33T1G for identical specifications. Verify pinout compatibility and thermal performance when considering cross-brand alternatives. Ensure replacement components meet the same SOT-23-5 package dimensions and electrical tolerances.
