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

Verify the specific ordering suffix 'YMM' corresponds to the MSOP-8 package variant rather than the SOT-23-5 configuration. Confirm that the '-TR' designation indicates tape-and-reel packaging for automated assembly processes. Ensure compatibility with RoHS3 standards and check for any recent Product Change Notifications regarding assembly locations or material composition updates.

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

Select this component when low output noise is critical, utilizing the BYP pin with a 470pF capacitor. Ensure the application requires an 8-pin footprint; otherwise, consider the SOT-23-5 version. Verify that the required output capacitance meets stability guidelines, specifically using at least 2.2µF when the bypass capacitor is active. Check that the system logic levels align with the CMOS-compatible enable threshold requirements.

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

This part belongs to the MIC5206 family of 150mA low-dropout regulators manufactured by Microchip Technology, formerly Micrel. The series offers high precision and low ground current optimized for portable electronics. The YMM suffix identifies the specific 8-pin MSOP package variant which includes the reference bypass feature not available in the smaller 5-pin packages.

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

How does the reference bypass pin affect stability?

Connecting a 470pF capacitor to the BYP pin reduces output noise but decreases phase margin. To maintain stability with this capacitor installed, an output capacitor of at least 2.2µF is generally required.

What is the function of the FLAG pin?

The FLAG pin is an open-collector output that goes active low when the output voltage drops below the nominal value by approximately 5%, indicating an undervoltage fault condition.
