MIC5305-2.5YML TR

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

The MIC5305-2.5YML TR is a single-channel, fixed-output Ultra Low Dropout (ULDO) linear regulator manufactured by Micrel. It provides a stable 2.5V output with a maximum current capacity of 150mA. The device operates within an input voltage range of 2.25V to 5.5V and features an extremely low dropout voltage of 60mV at full load. Packaged in a compact 6-pin 2mm x 2mm MLF leadless format, it utilizes µCap technology for stability with small ceramic capacitors. Key electrical specifications include a typical quiescent current of 90µA, high power supply rejection ratio exceeding 65dB at 1kHz, and initial output accuracy of ±1%.

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

• Ultra-low dropout voltage performance ensures efficient operation even when the input voltage is close to the output level.
• High power supply rejection ratio effectively attenuates noise from the input source, providing clean power for sensitive circuitry.
• µCap design allows for the use of very small ceramic output capacitors, significantly reducing board space and component costs.
• Logic-compatible enable pin facilitates precise power management by allowing the device to enter a zero-off-mode state with no current draw.

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

Verify that the specific suffix 'TR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the manufacturer designation aligns with Micrel or its successor entity Microchip Technology to ensure authenticity. Check for RoHS compliance status if environmental regulations apply to the final product assembly. Ensure the fixed 2.5V output voltage matches the target circuit requirements precisely.

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

Select this component when a single regulated rail is sufficient for the application design. The 150mA output current capability supports moderate load demands typical in portable consumer electronics. The 2mm x 2mm MLF package is optimal for designs with strict spatial constraints on the printed circuit board. Consider the 90µA quiescent current for battery life optimization in standby modes enabled by the logic-compatible control pin.

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

This part belongs to the MIC5305 family of ultra-low dropout regulators designed for space-constrained portable applications. The family offers various fixed output voltages and adjustable options across different package types including TSOT-23-5 and Thin MLF. The MIC5305 series is characterized by its µCap stability technology and high PSRR, making it suitable for powering RF and noise-sensitive components in mobile devices.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes within the same family include other MIC5305 variants with different fixed output voltages, such as MIC5305-2.85YML TR or MIC5305-3.3YML TR, provided the voltage requirement differs. For adjustable output needs, the MIC5305-ADJYML TR may be considered. Cross-manufacturer replacements require verification of pinout compatibility, thermal characteristics, and electrical parameters against the original datasheet specifications.
