MIC5310-SNYML

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

The MIC5310-SNYML is a dual-output ultra-low dropout linear regulator manufactured by Micrel. It integrates two independent 150mA LDOs within an 8-pin, 2mm x 2mm MLF leadless package. The device operates with an input voltage range of 2.3V to 5.5V and features fixed output voltages of 1.8V and 3.3V. Key electrical characteristics include a dropout voltage of 0.1V at 150mA per channel, a quiescent current of 190µA, and power supply rejection ratio (PSRR) exceeding 70dB at 1kHz. The component supports operation across a temperature range of -40°C to +125°C and includes overcurrent and thermal shutdown protection.

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

Verify the specific suffix 'SNYML' against official Microchip documentation to confirm exact output voltage combinations and package variations. Ensure compatibility with the 2.3V to 5.5V input range and 150mA load requirements. Confirm that the 8-MLF package dimensions align with the target PCB footprint. Cross-reference the manufacturer's latest datasheet for any updates on pinout or electrical specifications prior to finalizing procurement.

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

Select this component when space-constrained designs require dual isolated outputs from a single package. The 150mA current rating suits moderate load applications, while the low dropout characteristic benefits battery-powered systems. Verify that the required output voltages match the fixed options available in the SNYML variant. Consider the thermal performance of the MLF package for high-density layouts.

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

The MIC5310 series belongs to Micrel's family of tiny dual ultra-low dropout linear regulators. These devices are designed to replace larger discrete solutions or single-channel regulators in portable applications. The series utilizes MicroCap technology to minimize external component count, reducing overall board area and cost compared to traditional SOT-6 packages.

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

Direct replacements may include other MIC5310 variants with different fixed output voltages, such as MIC5310-SGYML or MIC5310-OGYML, provided the output voltage requirements match. Ensure the replacement maintains the same 8-MLF package and 150mA current rating.
