MIC5157BM TR

Overview

The MIC5157BM TR is a Super LDO voltage controller manufactured by Microchip Technology, designed for low-dropout regulator applications. It operates within an input voltage range of 3 V to 36 V and supports fixed output voltages of 3.3 V, 5 V, and 12 V. The device features a quiescent current of 4.5 mA and functions reliably across a temperature range from -40 °C to +85 °C. Packaged in a 14-SOIC surface-mount format, it serves as a power management IC suitable for systems requiring precise voltage regulation with minimal external component complexity.

Feature Summary

• Regulator-selectable architecture allowing configuration for specific fixed output voltages
• Super LDO design optimized for stable operation with low dropout characteristics
• Integrated protection mechanisms ensuring reliable performance under varying load conditions

Applications

• Portable electronic devices requiring efficient power management
• Industrial control systems needing stable voltage rails

Procurement Notes

Verify the exact suffix and tape-and-reel quantity against the manufacturer's latest datasheet before ordering. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the SOIC-14 package dimensions match your PCB footprint specifications precisely to avoid mounting issues during production.

Selection Notes

Choose this component when a fixed output voltage such as 3.3 V, 5 V, or 12 V is required without external adjustment resistors. It is suitable for designs prioritizing low quiescent current and wide input voltage tolerance. Consider the 14-SOIC package constraints and thermal dissipation capabilities relative to your system's power budget and ambient operating environment.
