Attached Qualification Report. Provided estimated first ship date to be on October 31, 2025.
Description of Change: Qualification of Microchip Technology Colorado ? Fab 5 (MCSO) as a new fabrication location for multiple device families available in various packages.Reason for Change: To improve manufacturability and on time delivery performance by qualifying a new fabrication location (MCSO - FAB 5), which is a Microchip-owned facility that offers significant expansion potential to better meet future client demand. *Note: The attached file called Tempe_Fab2_IATF_Decertification is for the manufacturing site deactivation of Microchip Technology Tempe ? Fab 2 (TMGR), contact your local Microchip sales office for inquiries.Estimated Qualification Completion Date: September 2025Pre and Post Summary Changes:? Pre Change: Fabrication Site = Microchip Technology Tempe ? Fab 2 (TMGR), Wafer Size = 8"? Post Change: Fabrication Site = Microchip Technology Colorado(MCSO), Wafer Size = 6"

Features & Applications
The MIC2937A-3.3WU TR is a Part of MIC2937A Series bulletproof” efficient voltage regulators with very low dropout voltage (typically 40 mV at light loads and 300 mV at 500 mA), and very low quiescent current (160 μA typical)
The quiescent current of the MIC2937A increases only slightly in dropout, thus prolonging battery life. Key MIC2937A features include protection against reversed battery, fold-back current limiting, and automotive “load dump”protection (60 V positive transient).
Features:
- High output voltage accuracy
- Guaranteed 750 mA output
- Low quiescent current
- Low dropout voltage
- Extremely tight load and line regulation
- Very low temperature coefficient
- Current and thermal limiting
- Input can withstand:
- –20 V reverse battery
- +60 V positive transients
- Error flag warns of output dropout
- Logic-controlled electronic shutdown
- Output programmable from 1.24 V to 26 V(MIC29372)
Applications:
- Battery Powered Equipment
- Cellular Telephones
- Laptop, Notebook, and Palmtop Computers
- PCMCIA VCC and VPP Regulation/Switching
- Bar Code Scanners
- Automotive Electronics
- SMPS Post-Regulator/ DC to DC Modules
- High Efficiency Linear Power Supplies
