CD5305

Current Regulation - Diodes, Transistors Overview

The MIC5305-2.85YML-TR is a fixed-output low-dropout (LDO) voltage regulator manufactured by Microchip Technology, providing a stable 2.85 V output with a maximum load current of 150 mA. It operates within an input voltage range of 2.25 V to 5.5 V and features a typical dropout voltage of 60 mV at full load. The device maintains a quiescent current of 90 µA and offers high power supply rejection ratio (PSRR) performance. Packaged in a compact 6-pin MLF format measuring 2 mm x 2 mm, it supports surface-mount installation and functions reliably across an extended temperature range from -40°C to +125°C.

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix codes on the component marking against official datasheets to confirm output voltage accuracy and package type. Ensure that ordering quantities align with manufacturer reel specifications. Confirm RoHS compliance status through certified documentation prior to integration into production environments.

Current Regulation - Diodes, Transistors Selection Notes

Select this regulator when board space is limited due to its ultra-compact MLF footprint. Consider the 150 mA current limit for loads exceeding this threshold. Evaluate thermal dissipation capabilities based on the expected ambient temperature and PCB copper area available for heat spreading during continuous operation.

Current Regulation - Diodes, Transistors Part Context

This component belongs to the MIC5305 family of µCap LDO regulators designed for high performance in small packages. The series includes various fixed output voltages and adjustable versions, all sharing common architectural benefits such as low ground current and stability with ceramic capacitors only.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include other MIC5305 variants with different fixed output voltages if system requirements change. Cross-brand replacements require matching input/output voltage ranges, current capacity, and package dimensions to ensure mechanical and electrical compatibility without redesigning the PCB layout.
