MIC5256-2.85BD5-TR

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

The MIC5256-2.85BD5-TR is a fixed-output CMOS low-dropout voltage regulator manufactured by Microchip Technology, providing a precise 2.85V output with a maximum continuous load current of 150 mA. It operates within an input voltage range of 2.7V to 6.0V and features an ultra-low dropout voltage of typically 135 mV at full load. The device incorporates an active-low error flag for fault indication, including overcurrent, thermal shutdown, and dropout conditions. It utilizes a thin TSOT-23-5 (D5) package and maintains stability with low-ESR ceramic capacitors.

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

• Integrated Error Flag: Provides an open-drain active-low output that signals undervoltage conditions resulting from overcurrent protection, thermal shutdown, or dropout events.
• Ultra-Low Dropout Performance: Delivers high efficiency with a typical dropout voltage of 135 mV at the maximum 150 mA load current.
• Active Shutdown Control: Features a TTL-compatible enable pin that forces the device into a near-zero off-mode current state when disabled, while actively discharging the output capacitor via an internal clamp.
• Ceramic Capacitor Stability: Designed specifically for use with low-ESR ceramic output capacitors, reducing board space requirements without compromising loop stability.

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

• Cellular phones and pagers
• Battery-powered equipment
• Laptop, notebook, and palmtop computers

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

Verify the specific ordering suffix 'D5' corresponds to the TSOT-23-5 package variant rather than the standard SOT-23-5. Confirm the 'TR' suffix indicates tape-and-reel packaging. Ensure the component meets RoHS compliance standards as specified in the datasheet documentation before finalizing procurement specifications.

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

Select this component for applications requiring a fixed 2.85V rail with minimal footprint constraints. The inclusion of the error flag makes it suitable for systems needing fault monitoring. Verify that the system's input voltage remains within the 2.7V to 6.0V operating range and that the load current does not exceed 150 mA continuously.

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

This part belongs to the MIC5256 series of 150 µCap LDO regulators featuring error flags. It shares core electrical characteristics with the MIC5255 series but adds the dedicated fault indication logic. The D5 suffix distinguishes it from the M5 package variant, offering a thinner profile suitable for compact handheld wireless devices.
