MIC29712BT

Overview

The MIC29712BT is a high-current, high-accuracy, low-dropout regulator featuring the Super Eta PNP process. It provides an adjustable output voltage range of 1.25V to 16V with a maximum input voltage of 16V. The device supports up to 7.5A output current and operates within a junction temperature range of 0°C to +125°C. Packaged in a TO-220-5 case for through-hole mounting, it includes TTL-compatible enable control and comprehensive protection against overcurrent, thermal overload, and reverse polarity.

Feature Summary

• Super Eta PNP technology ensures rapid transient response and low ground current
• Integrated protection against overcurrent faults, thermal overload, and reversed leads
• TTL-compatible enable pin allows external on/off control or continuous operation

Applications

• Intel Pentium and Pentium Plus processor power supplies
• High-efficiency linear power systems
• Post-regulation for switching power supplies
• Battery-powered equipment requiring low dropout

Procurement Notes

Verify the specific suffix 'BT' indicates the standard operating temperature range (0°C to +125°C) as defined in the official datasheet. Confirm package type is TO-220-5. Ensure compatibility with Intel Pentium Plus architecture requirements before procurement.

Selection Notes

Select this model when adjustable output voltage between 1.25V and 16V is required. It is suitable for applications needing 7.5A current capability with fast transient recovery. Choose over fixed versions if variable voltage regulation is necessary for the target load.

Part Context

Part of the MIC2971x family of large current, high accuracy, low dropout regulators. Shares core Super Eta PNP technology with MIC29710 but offers adjustable output via five-pin configuration instead of fixed three-pin options.

Replacement Considerations

MIC29712W is the surface-mount equivalent. MIC29752 series serves as an alternative for inputs exceeding 16V or requiring lower dropout voltages.
