Overview
The MIC29710-3.3WT is a high-current, low-dropout linear voltage regulator manufactured by Microchip Technology. It provides a fixed 3.3V output with a maximum current capability of 7.5A. The device operates within an input voltage range of 2.5V to 16V and features a typical dropout voltage of 700mV at full load. It includes TTL-compatible enable control, overcurrent protection, thermal shutdown, and reverse battery protection. The component is housed in a TO-220 package and supports junction temperatures up to +125°C.
Feature Summary
- SuperEta PNP technology enables fast transient response and low ground current.
- Integrated protection against overcurrent, thermal overload, and reverse polarity.
- TTL-compatible enable pin allows for external on/off switching control.
Applications
- Power supply for Intel Pentium and Pentium Pro processors
- High-efficiency linear power supplies
- Post-regulation for switching power supplies
- Battery-powered equipment requiring low dropout
Procurement Notes
Verify the specific suffix 'WT' corresponds to the TO-220 through-hole package variant when sourcing. Confirm that the fixed 3.3V output version matches the design requirement, as adjustable versions exist within the same family. Ensure the application does not exceed the 7.5A continuous current rating or the thermal limits defined in the datasheet for the selected enclosure.
Selection Notes
Select this model for applications requiring high current delivery with minimal voltage drop from a 16V input source. The fixed 3.3V output eliminates the need for external feedback resistors. Consider the TO-220 package's thermal dissipation capabilities relative to the expected load current and ambient temperature conditions to ensure reliable operation without additional heatsinking if possible.
Part Context
This component belongs to the MIC29710/29712 series of SuperEta regulators. These devices utilize proprietary PNP bypass elements to achieve superior performance compared to standard NPN-based LDOs. The series is designed for demanding computing and industrial applications where stability under rapid load changes is critical.
