Article Details
MIC5365-1.8YC5-TR from Microchip Technology is a fixed 1.8 V low-dropout linear regulator designed for compact, low-power electronic systems. As a single-output 150 mA LDO regulator in an SC-70-5 package, it is suitable for portable devices, embedded controllers, wireless modules, sensor circuits, and space-limited PCB designs that require clean and stable local power regulation.
MIC5365-1.8YC5-TR Overview
The MIC5365-1.8YC5-TR is part of Microchip's MIC5365/6 family of high-performance single LDO voltage regulators. It provides a fixed 1.8 V output and supports up to 150 mA output current, making it useful for powering low-voltage ICs, microcontrollers, analog front ends, RF sections, and peripheral circuits.
With a 2.5 V to 5.5 V input voltage range, low quiescent current, high PSRR, and stable operation with small ceramic capacitors, this regulator is well suited for battery-powered and distributed power architectures.

Design Advantages
MIC5365-1.8YC5-TR is useful when a design needs a simple fixed 1.8 V rail without the switching noise of a DC-DC converter. Its compact SC-70-5 package helps save PCB space, while the ability to work with small ceramic capacitors supports dense layouts in portable and embedded products.
Compared with larger linear regulators, this device reduces board area and is easier to place near the load. Compared with a switching regulator, it offers lower design complexity and cleaner output for noise-sensitive sections, although it is best suited for lower-current rails where linear regulation efficiency is acceptable.
Where MIC5365-1.8YC5-TR Fits in Power Design
The device is typically used as a local point-of-load regulator. A main system rail such as 3.3 V or 5 V can feed the MIC5365-1.8YC5-TR, which then generates a stable 1.8 V output for downstream ICs. This is a common approach in systems that combine processors, sensors, wireless modules, and low-voltage digital logic.
Its low quiescent current is helpful in always-on or standby circuits. The high PSRR also makes it a practical option when the upstream supply comes from a switching converter and additional supply filtering is required before powering sensitive loads.
