MIC5357-SGYMME-TR

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

The MIC5357-SGYMME-TR is a dual-channel low-dropout (LDO) linear voltage regulator manufactured by Microchip Technology. It features two independent outputs with fixed voltages of 1.8 V and 3.3 V, each capable of delivering up to 500 mA of output current. The device utilizes an MSOP-8 package for surface-mount installation. Key electrical specifications include a typical power supply rejection ratio (PSRR) of 70 dB, a quiescent current of 160 µA, and a maximum dropout voltage of 130 mV. It operates within a temperature range of -40°C to +125°C.

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

Verify the specific suffix SGYMME against official Microchip documentation to confirm the exact output voltage combination and package variant. Ensure compatibility with MSOP-8 footprint requirements during PCB layout. Cross-reference datasheet parameters such as PSRR and dropout voltage against application needs. Confirm RoHS compliance status through authorized distributors or manufacturer channels prior to ordering.

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

Select this component when dual isolated LDO outputs are required in a space-constrained design. The 500 mA rating supports moderate-to-high current loads compared to standard 150 mA regulators. Consider the 160 µA quiescent current for battery life optimization. Verify that the input voltage range accommodates the source supply while maintaining the specified dropout margins for both 1.8 V and 3.3 V outputs across the full operating temperature range.
