MIC29201-5.0BT

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The MIC29201-5.0BT is a fixed-output low-dropout voltage regulator providing a 5.0V output with a guaranteed maximum load current of 400mA. It operates within an input supply voltage range of 2V to 26V and features a junction temperature range from -40°C to +125°C. The device incorporates logic-controlled electronic shutdown and an error flag output for dropout detection. It utilizes a TO-220-5 through-hole package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Includes a logic-compatible shutdown pin for power control and an open-collector error flag output that signals when the regulator falls out of regulation.
• Provides robust protection against reversed battery connections up to -20V and withstands automotive load dump positive transients up to 60V.
• Features fold-back current limiting and thermal limiting to protect the device under short-circuit or high-power dissipation conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

• Automotive electronics requiring load dump protection
• Battery-powered equipment
• Cellular telephones
• Laptop, notebook, and palmtop computers

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'BT' corresponds to the TO-220-5 package configuration as documented in the official ordering information. Confirm that the manufacturer designation aligns with the original Micrel specifications now managed by Microchip Technology. Ensure the component meets the required RoHS compliance standards indicated for the standard lead-free version.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 5V output is required alongside active shutdown capabilities and dropout monitoring. The TO-220-5 package is suitable for applications needing higher thermal dissipation compared to surface-mount options. Verify that the system design accommodates the external pull-up resistor required for the error comparator output functionality.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the MIC2920A family of 400mA low-dropout regulators manufactured originally by Micrel, Inc. and currently supported by Microchip Technology. The MIC29201 variant specifically adds a shutdown input and an error flag output compared to the basic MIC2920A fixed regulators. The family is characterized by very low quiescent current and tight line and load regulation specifications.
