Linear & Switching Voltage Regulators

MIC94345-GYMT-TR Description

The MIC94345-GYMT-TR is a high-performance linear voltage regulator designed by Microchip Technology, offering a fixed output voltage of 1.8V and capable of delivering up to 500mA of current. This regulator is part of the Ripple Blocker™ series, known for its superior performance in filtering out ripple and noise from the power supply. The device operates with an input voltage range up to 3.6V and features a low dropout voltage of 0.2V at 500mA, making it highly efficient even under low input-to-output voltage differentials. The regulator is housed in a compact 6TDFN package, suitable for surface mount applications, and is available in tape and reel (TR) format for convenient manufacturing processes.

MIC94345-GYMT-TR Features

• Fixed Output Voltage: Provides a stable 1.8V output, ensuring consistent performance in applications requiring a fixed voltage supply.
• High Output Current: Capable of delivering up to 500mA, making it suitable for a wide range of applications that demand moderate to high current levels.
• Low Dropout Voltage: With a maximum dropout voltage of 0.2V at 500mA, the regulator maintains high efficiency even when the input voltage is close to the output voltage.
• Low Quiescent Current: Consumes only 250 µA in quiescent mode, which is beneficial for battery-powered devices and low-power applications.
• High PSRR: Offers a wide range of power supply rejection ratio (PSRR) from 85dB at 100Hz to 50dB at 5MHz, effectively reducing noise and ripple in the output voltage.
• Enable Control Feature: Includes an enable pin for easy control and shutdown, allowing the regulator to be turned off when not in use, further conserving power.
• Protection Features: Equipped with over-current and over-temperature protection, ensuring reliable operation and safeguarding against potential damage.
• Compliance and Reliability: The regulator is REACH unaffected and RoHS3 compliant, meeting stringent environmental and safety standards. It also has a moisture sensitivity level (MSL) of 1, indicating it is suitable for unlimited exposure to normal indoor environmental conditions.
