Microchip Technology MIC5365-1.8YC5-TR

The MIC5365-1.8YC5-TR supplies a regulated 1.8 V rail and supports loads up to 150 mA. The family operating input range is 2.5 V to 5.5 V, while this 1.8 V option requires VIN to remain above VOUT by the applicable dropout margin. It combines low typical ground current, high power-supply rejection, ceramic-capacitor stability, shutdown control, current limiting, and thermal shutdown for compact portable and mixed-signal designs.

The exact C5 order-code suffix identifies Microchip's 5-lead SC-70 package. The catalog field also lists generic or alternate aliases; the manufacturer-controlled SC-70-5 designation and existing registered image are used here.

Layout checks

• Verify the SC-70-5 pin-1 indicator and land pattern before release.
• Place the input and output capacitors close to their pins and the ground return.
• Keep the enable trace at a defined logic level and away from noisy switching nodes.
• Check junction temperature from voltage drop, load current, copper area, and ambient conditions.

The configured local JPG exists and was visually checked as a five-lead SC-70 style package illustration. Production availability is verified separately before publication.

The following assignment is for the C5 SC-70-5 package.

The four-lead DFN version uses a different pin arrangement; use the SC-70-5 drawing for this exact order code.

Typical and maximum values depend on the stated electrical test conditions. For a 1.8 V output, maintain sufficient input headroom for the required load current.

Replacement selection must preserve the 1.8 V fixed output, 150 mA load requirement, SC-70-5 footprint and pin order, input range, active-high enable behavior, capacitor stability, and thermal performance. MIC5366 adds output discharge, and other voltage or package variants require separate electrical and mechanical review; they are not unconditional substitutes.

No internal replacement link is asserted without an exact catalog match and an engineering review of compatibility.

Microchip Technology identifies MIC5365 as a high-performance single 150 mA LDO. The `-1.8` segment specifies the 1.8 V output, `Y` specifies the -40 degrees C to +125 degrees C junction-temperature option, `C5` specifies the five-lead SC-70 package, and `TR` is the tape-and-reel media designator.

Confirm the full order code, reel label, package marking, pin-1 indicator, and traceability information during incoming inspection. Electrical verification should use the limits and conditions in the latest manufacturer-controlled data sheet. Package appearance alone does not establish authenticity or compliance.

Validate dropout headroom, load transients, capacitor bias derating, thermal rise, enable thresholds, and the exact SC-70-5 land pattern in the final circuit. Do not exceed the operating ratings, and calculate junction temperature from actual input voltage, output voltage, load current, ambient temperature, and board thermal conditions.
