MIC5158YM-TR

Voltage Regulators - Linear Regulator Controllers Overview

The MIC5158YM-TR is a Super LDO Regulator Controller manufactured by Microchip Technology, housed in an 8-pin SOIC package. It operates within a supply voltage range of 3V to 36V and supports an operating temperature range from -40°C to +85°C. The device features a typical operating current of 4.5mA and a shutdown current below 1µA. It includes an internal charge pump tripler for gate drive generation and offers configurable fixed 5V or adjustable output voltages ranging from 1.3V to 36V.

Voltage Regulators - Linear Regulator Controllers Feature Summary

• Integrates an internal charge pump tripler to generate the necessary gate drive voltage for external N-channel MOSFETs without requiring an external supply.
• Provides flexible output configuration options, supporting either a fixed 5V setting or programmable output voltages via external resistors.
• Includes an active-low open-collector flag output that signals when the regulated output voltage drops significantly below its nominal value.
• Features an internal gate-to-source protective clamp to safeguard the external power MOSFET against overvoltage conditions.

Voltage Regulators - Linear Regulator Controllers Applications

• Ultrahigh current ultralow dropout voltage regulators
• Low noise or low-dropout SMPS post regulators
• Constant high-current sources
• High-current, current-limited switches

Voltage Regulators - Linear Regulator Controllers Procurement Notes

Verify the specific suffix 'YM' corresponds to the 14-pin SOIC package variant as indicated in official documentation. Confirm RoHS compliance status and ensure the component meets environmental standards required for the target application. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Voltage Regulators - Linear Regulator Controllers Selection Notes

Select this controller when a single IC solution is needed for high-current linear regulation using an external pass element. It is suitable for designs requiring an internal charge pump to simplify gate drive circuitry compared to variants needing external supplies. Ensure the external MOSFET selection aligns with the logic-level requirements for optimal performance at lower input voltages.

Voltage Regulators - Linear Regulator Controllers Part Context

This component belongs to the MIC5156/5157/5158 family of Super LDO Regulator Controllers. While the MIC5156 requires an external gate drive supply, the MIC5158 integrates a charge pump tripler. It shares functional similarities with the MIC5157 but differs in output configuration flexibility, offering both fixed and adjustable modes rather than selectable fixed voltages.
