MIC5156-5.0YM-TR

Overview

The MIC5156-5.0YM-TR is a Super LDO Regulator Controller manufactured by Microchip Technology, housed in an 8-pin SOIC package. It provides a fixed 5.0V output with a supply voltage range of 3V to 36V and operates within a temperature range of -40°C to +85°C. The device features a typical operating current of 2.7mA and a shutdown current below 1µA. It includes an open-collector flag for out-of-regulation detection and supports optional constant-current limiting via an external sense resistor.

Feature Summary

• Fixed 5.0V output configuration with high initial accuracy
• Internal gate-to-source protective clamp for MOSFET safety
• TTL-compatible enable pin for low-power shutdown control
• Open-collector flag output for fault condition signaling

Applications

• Ultrahigh current ultralow dropout voltage regulator
• Low parts count 5.0V to 3.3V computer supply
• High-current, current-limited switch
• Constant high-current source

Procurement Notes

Verify the specific ordering suffix 'YM-TR' confirms the 8-pin SOIC package and tape-and-reel packaging format. Ensure the component matches the Microchip Technology manufacturer identification. Confirm RoHS compliance status through official documentation before integration into production designs.

Selection Notes

Select this controller when a fixed 5.0V output is required without external programming resistors. It is suitable for applications needing low standby power consumption and integrated protection against gate overdrive. Consider the need for an external N-channel MOSFET as the pass element to handle high load currents.

Part Context

This component belongs to the MIC5156/5157/5158 family of Super LDO Regulator Controllers. Unlike the MIC5157 and MIC5158, the MIC5156 requires an external gate drive supply voltage rather than an internal charge pump. It is available in both adjustable and fixed voltage variants, offering flexibility for various linear regulation topologies.

Replacement Considerations

MIC5156-5.0BM (Tube) offers identical electrical specifications in a tube package instead of tape-and-reel.
