Overview
The S-1111B29MC-NYOTFG is a linear voltage regulator IC from the ABLIC Inc. S-1111 series, manufactured by MinebeaMitsumi. It provides a fixed positive output voltage of 2.9V with a maximum output current of 150mA. The device utilizes a SOT-23-5 package and operates as a low-dropout regulator (LDO). It is RoHS3 compliant and packaged in Tape & Reel format.
Feature Summary
- Provides stable fixed voltage regulation for low-power electronic circuits
- Designed for extended battery operation through super low current consumption
- Compact surface-mount packaging suitable for space-constrained designs
Applications
- Battery-powered portable devices requiring precise voltage levels
- Low-power consumer electronics systems
- Quartz watch timer ICs and system control applications
Procurement Notes
Verify the manufacturer designation, as sources may list SII Semiconductor Corporation or ABLIC Inc., both part of the MinebeaMitsumi Group. Confirm the specific suffix NYOTFG corresponds to the Tape & Reel packaging and RoHS3 compliance status required for your assembly process. Ensure the 2.9V output matches your circuit design specifications before ordering.
Selection Notes
Select this component when a fixed 2.9V supply is needed with minimal quiescent current draw. The SOT-23-5 package offers a compact footprint for dense PCB layouts. Consider the 150mA output limit to ensure it meets the load requirements of your target application without exceeding thermal constraints.
Part Context
This part belongs to the S-1111 series of ultra-low power LDO regulators. ABLIC Inc., now integrated into MinebeaMitsumi, specializes in high-precision analog semiconductors. The series is known for combining small size with low power consumption, making it suitable for timekeeping and low-energy monitoring applications.
Replacement Considerations
Check for other S-1111 variants with different output voltages if 2.9V is not required. Verify pin compatibility for direct replacement within the SOT-23-5 form factor. Consult official datasheets for electrical parameter matching rather than relying on generic family similarities.
