NCP102SNT1G

Overview

The NCP102SNT1G is a Low Dropout Linear Regulator Controller manufactured by onsemi. It operates with an input voltage range from 4.5V to 13.5V and supports adjustable output configurations. The device requires an external N-channel pass transistor for operation. It is housed in a surface-mount SOT-23-5 package, designed for efficient power management in applications requiring precise voltage regulation with minimal quiescent current consumption.

Feature Summary

• Supports adjustable output voltage via external resistor network
• Requires external N-channel MOSFET pass device
• Operates within wide input voltage range up to 13.5V

Applications

• Battery-powered portable devices
• Embedded systems requiring adjustable supply rails
• Industrial control modules

Procurement Notes

Verify the specific datasheet revision and ordering suffix to ensure compatibility with your design requirements. Confirm that the external N-channel pass transistor meets the controller's drive specifications. Check for any recent product change notices or end-of-life announcements from onsemi before finalizing procurement plans.

Selection Notes

Select this component when an adjustable LDO solution is needed with low quiescent current. Ensure the external N-channel MOSFET selected can handle the required load current and voltage ratings. Consider thermal dissipation capabilities of the SOT-23-5 package under maximum load conditions.

Part Context

Part of onsemi's NCP102 family of linear regulator controllers. Designed for cost-sensitive applications where discrete components are preferred over integrated LDOs for flexibility. Commonly used in consumer electronics and industrial equipment.

Replacement Considerations

Check for direct pin-compatible alternatives within the NCP102 series. Verify electrical parameters such as input voltage range and quiescent current match application needs.
