MIC5310-SGYML

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

The MIC5310-SGYML is a dual-output ultra-low dropout linear regulator manufactured by Microchip Technology. It integrates two independent 150mA LDOs within an 8-pin MLF package measuring 2mm x 2mm. The device supports an input voltage range of 2.3V to 5.5V. Output configurations include fixed voltages such as 1.8V and 3.3V. Key electrical characteristics include a dropout voltage of 0.1V at 150mA load, quiescent current of 190µA, and power supply rejection ratio exceeding 65dB at 1kHz. The component operates across a temperature range of -40°C to 125°C.

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

Verify the specific suffix against official Microchip documentation to confirm exact output voltage combinations and tape-and-reel specifications. Ensure the ordering part number matches the required fixed output pair, as variations exist within the MIC5310 family. Confirm package type and thermal requirements align with the target PCB layout before finalizing procurement orders.

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

Select this component when board space is limited due to its tiny 2mm x 2mm footprint. Choose this device for applications requiring dual independent rails from a single source. Consider the µCap capability if minimizing external capacitor size is critical. Verify that the 150mA per channel current rating meets the peak load demands of the connected subsystems.

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

This component belongs to the MIC5310 series of dual ultra-low dropout linear regulators. The series is designed for portable electronics where efficiency and size are paramount. It shares architectural similarities with other Micrel/Microchip ULDO products but distinguishes itself through the integration of two channels in a minimal leadless package format optimized for thermal performance.

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

Direct substitutes may include other dual LDOs in 2x2mm packages from Microchip or Micrel. Verify pinout compatibility and output voltage accuracy before substitution. Check if alternative devices offer similar quiescent current and dropout characteristics to maintain system power budget.
