MIC94325YMT-TR

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

The MIC94325YMT-TR is a single-output adjustable low-dropout (LDO) voltage regulator from Microchip Technology, featuring Ripple Blocker™ technology for active noise suppression. It operates within an input voltage range of 1.8V to 3.6V and provides an adjustable output voltage between 1.2V and 3.4V with a maximum continuous output current of 500mA. The device maintains high power supply ripple rejection (PSRR) across a frequency range of 100Hz to 5MHz. It includes logic-controlled enable functionality and offers protection against overcurrent and thermal overload conditions.

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

• Integrates Ripple Blocker™ technology to actively attenuate low-frequency switching noise and improve system efficiency in noisy environments.
• Maintains high power supply ripple rejection performance even when the input voltage is close to the regulated output level.
• Features a low-voltage logic control enable pin that facilitates simple ON/OFF management compatible with standard GPIO signals.

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

• Smartphones and mobile computing devices
• Tablets, laptops, and webcams
• GPS modules and automotive systems

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

Verify the specific suffix 'T5' or 'TR' matches your required packaging format, as these indicate different reel configurations. Confirm RoHS compliance status through official documentation before finalizing procurement. Ensure the supplier source is authorized to guarantee component authenticity and traceability. Check for any recent PCN updates regarding assembly sites or material changes.

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

Select this component when designing circuits powered by DC/DC converters where downstream RF or sensitive analog circuits cannot tolerate switching noise. Choose the adjustable version for flexible voltage requirements within the specified range. Ensure the application environment stays within the -40°C to +125°C junction temperature limits. Verify that the input voltage does not exceed the 3.6V maximum rating.

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

This part belongs to the MIC943x5 series of LDO regulators, which also includes fixed-output variants like the MIC94345 and MIC94355. All members share the same core Ripple Blocker™ architecture and compact 6-TDFN package. The MIC94325 specifically provides the adjustable output option, distinguishing it from the fixed 3.3V and 5.0V versions in the family.

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

Direct functional substitutes within the same series include MIC94345YMT-TR (fixed 3.3V) and MIC94355YMT-TR (fixed 5.0V). These parts share identical packages and noise suppression features but lack adjustable output capability. Verify if the fixed voltage meets the design requirements before substitution.
