MIC5219YMM

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

The MIC5219YMM is an adjustable linear voltage regulator in an 8-pin MSOP package. It supports a supply input voltage range of +2.5V to +12V and delivers up to 500 mA continuous output current. The device features a maximum dropout voltage of 600 mV at full load, better than 1% output voltage accuracy, and ultra-low noise performance with an optional bypass capacitor. It includes CMOS/TTL-compatible enable/shutdown control, near-zero shutdown current, reversed-battery protection, and thermal/overcurrent limiting.

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

• Adjustable output voltage configuration via external resistive divider network
• Ultra-low noise performance enabled by connecting an external capacitor to the BYP pin
• Integrated safety mechanisms including current limiting, thermal shutdown, and reversed-battery protection

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

• Laptop, notebook, and palmtop computers
• Cellular telephones and battery-powered equipment
• PC Card VCC and VPP regulation and switching
• SMPS post-regulator and DC-to-DC modules

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

Verify that the specific order corresponds to the adjustable variant (MIC5219YMM) rather than fixed-voltage versions. Confirm the package type matches the required 8-lead MSOP footprint. Ensure the application design accounts for the necessary external feedback resistors to set the desired output voltage level.

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

Select this component when space-constrained designs require high peak output current capability from a low-profile package. It is suitable for applications demanding extremely tight line and load regulation alongside low temperature coefficients. Consider the MSOP-8 package for improved thermal dissipation compared to smaller form factors.

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

This part belongs to the MIC5219 family of 500 mA peak output LDO regulators manufactured by Microchip Technology. The YMM suffix specifically denotes the adjustable output version housed in an 8-lead Power MSOP package. Other variants in the series include fixed-output voltages and different package options such as SOT-23-5 and VDFN.
