MIC5357-MGYMME

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

The MIC5357-MGYMME is a dual ultra-low dropout linear regulator from Microchip Technology, housed in an 8-MSOP package with an exposed pad. It provides two fixed output voltages of 1.8V and 2.8V, each capable of delivering up to 500mA of output current. The device operates within an input voltage range up to 5.5V and features a typical power supply rejection ratio (PSRR) of 70dB. It maintains operation across a temperature range of -40°C to +125°C with a maximum dropout voltage of 130mV and a quiescent current of 160µA.

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

Verify the specific suffix MGYMME against the official Microchip datasheet to confirm the 1.8V/2.8V output combination and MSOP-EP package type. Ensure compatibility with your PCB footprint, particularly the exposed thermal pad requirements. Cross-reference the RoHS status and operating temperature range with your system specifications before finalizing procurement.

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

Select this component when dual fixed outputs are required in a compact surface-mount package. The 500mA per channel rating suits moderate current loads, while the low quiescent current supports battery life extension. Consider the 130mV dropout voltage relative to your minimum input voltage headroom needs.
