LC101N

Overview

The LC101N is a linear LED driver IC manufactured by Sanken Electric USA Inc., designed for constant current regulation. It features a single output channel capable of delivering up to 150mA. The device operates within a supply voltage range of 2.4V to 35V and supports an output voltage of up to 35V. Packaged in an 8-DFN (2.7x2.5mm) surface-mount format with a bare pad, it functions without internal switching or dimming capabilities. The component is rated for junction temperatures between -40°C and 125°C.

Feature Summary

• Linear topology for stable constant current regulation
• Single-channel output design
• Surface-mount package with exposed thermal pad

Applications

• LED backlighting systems
• General LED illumination

Procurement Notes

Verify the specific ordering suffix required for your production needs, as the LC101N is available in both cut tape and reel configurations. Confirm that the 8-DFN footprint matches your PCB layout constraints. Ensure compliance with RoHS3 standards and check moisture sensitivity level classifications prior to assembly processing.

Selection Notes

Select this component when a simple, low-component-count solution for driving LEDs at currents up to 150mA is required. The linear architecture suits applications where noise immunity is prioritized over high-efficiency conversion. Consider the 35V output limit and 2.4V minimum input requirement when designing the power stage.

Part Context

The LC101N belongs to Sanken Electric's portfolio of power management integrated circuits, specifically within the LED driver category. As a linear regulator, it differs from switching drivers by offering simpler control loops and reduced electromagnetic interference, making it suitable for compact consumer electronics and lighting modules requiring precise current control.

Replacement Considerations

No public confirmed substitute part numbers are documented for the LC101N.
