Product details
Overview
MIC5365-2.6YC5-TR from Micrel is a fixed-output 2.6V, 150mA low-dropout linear regulator in SC-70-5 package, delivering ±2% initial output accuracy, 155mV dropout at full load, and 29µA quiescent current - optimized for power-sensitive portable electronics such as GPS modules and handheld devices.
For engineers reviewing the MIC5365-2.6YC5-TR datasheet, MIC5365-2.6YC5-TR pinout, MIC5365-2.6YC5-TR application, or MIC5365-2.6YC5-TR equivalent, key selection criteria include input voltage range (2.5V–5.5V), thermal shutdown protection, stability with 1µF ceramic output capacitors, and zero-off-mode operation enabling ultra-low standby power.
Technical Context
The MIC5365-2.6YC5-TR uses a CMOS-based pass element with active-high enable control and internal current limiting. Its architecture supports stable regulation down to zero load while maintaining 70dB PSRR up to 1kHz and 65dB from 1–10kHz.
It operates across –40°C to +125°C junction temperature, requires no external compensation, and achieves fast 50–125µs turn-on time with 1µF output capacitance - all within a 2.0mm × 1.25mm SC-70-5 footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.6V ±2% initial accuracy ensures reliable biasing of 2.5–2.7V logic rails without trimming. |
| Max Output Current | 150mA guaranteed - sufficient to power baseband processors, RF transceivers, or sensor subsystems in compact portable designs. |
| Dropout Voltage | 155mV @ 150mA - enables operation from 2.75V input when VOUT = 2.6V, preserving battery runtime in single-cell Li-ion or Li-poly systems. |
| Quiescent Current | 29µA typical - minimizes standby power loss in always-on GPS or real-time clock keep-alive circuits. |
| PSRR | 70dB @ ≤1kHz - suppresses switching noise from adjacent DC/DC converters feeding shared input rails. |
| Input Voltage Range | 2.5V to 5.5V - compatible with single-cell Li-ion (2.7–4.2V), USB-powered (4.5–5.5V), and regulated 3.3V system rails. |
| Thermal Shutdown | Integrated protection activates at ~150°C junction - prevents damage during transient overloads or poor PCB thermal design. |
Pinout & Package
SC-70-5 package: 2.0mm × 1.25mm × 0.9mm body, lead-free (RoHS-compliant), 5-pin surface-mount with exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main supply input; accepts 2.5–5.5V; requires 1µF X5R/X7R ceramic bypass capacitor to ground. |
| 2 | GND | Analog/digital ground reference; must be low-impedance connection to PCB ground plane. |
| 3 | EN | Active-high enable; drives ON above 1.2V, OFF below 0.2V; must not float - tie to VIN or controller GPIO. |
| 4 | VOUT | Regulated 2.6V output; stable with ≥1µF ceramic capacitor; supports no-load regulation. |
| 5 | NC | No-connect terminal; internally unconnected - leave unpopulated or floating (no PCB trace). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small SC-70-5 footprint | 2.0mm × 1.25mm area - saves >75% board space vs. SOT-23-5, ideal for space-constrained mobile PCBs. |
| Zero-off-mode current | Sub-1µA shutdown current - eliminates battery drain in powered-off states for GPS trackers and wearables. |
| 1µF ceramic capacitor stability | Eliminates need for large tantalum or electrolytic output caps - reduces BOM cost and improves reliability. |
| High PSRR (70dB @ 1kHz) | Enables clean LDO supply in noisy mixed-signal environments without additional filtering stages. |
| ±2% output accuracy | Meets tight tolerance requirements of 2.6V I/O interfaces and analog sensor references without calibration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC5365-2.6YMT | Same electrical specs, but in 1mm × 1mm Thin MLF-4 package (4-pin, no NC pin); higher thermal resistance (240°C/W vs. 256.5°C/W). | Better suited for ultra-dense layouts where 1mm² footprint is critical; lacks NC pin, simplifying routing but removing optional grounding option. | Select MIC5365-2.6YMT when board area is constrained below 2.5mm² and thermal margin allows higher θJA. |
| Torex XC6206P262MR-G | 2.6V, 150mA LDO with 30µA IQ and 160mV dropout; requires 1µF ceramic cap; no enable pin - always-on operation. | Applicable where enable control is unnecessary (e.g., always-powered medical sensors); lacks shutdown mode, increasing standby power. | Choose XC6206P262MR-G only if enable functionality is unused and PCB layout favors its SOT-25 package. |
Compared with MIC5365-2.6YMT, the MIC5365-2.6YC5-TR offers easier enable routing and lower thermal resistance in SC-70-5, while XC6206P262MR-G trades off controllability for slightly smaller SOT-25 size and no enable logic overhead.

FAQ
What is the maximum input voltage rating for the MIC5365-2.6YC5-TR?
The MIC5365-2.6YC5-TR has an absolute maximum input voltage of 6V, but its specified operating range is 2.5V to 5.5V. Exceeding 5.5V may cause permanent damage or violate safety margins defined in the datasheet's Absolute Maximum Ratings table. Always maintain VIN within 2.5–5.5V for reliable operation of the MIC5365-2.6YC5-TR.
Does the MIC5365-2.6YC5-TR require an external output capacitor, and what type is recommended?
Yes, the MIC5365-2.6YC5-TR requires a minimum 1µF ceramic output capacitor for stability. X5R or X7R dielectric types in 0402 or 0603 case sizes are explicitly recommended; Y5V and Z5U are discouraged due to excessive capacitance drift over temperature. The MIC5365-2.6YC5-TR remains stable with no load, unlike many legacy LDOs.
Is the MIC5365-2.6YC5-TR pin-compatible with the MIC5366-2.6YC5-TR?
No - the MIC5365-2.6YC5-TR and MIC5366-2.6YC5-TR share identical pinout and package (SC-70-5), but differ functionally: MIC5366 includes an auto-discharge NFET (30Ω) activated during shutdown, while MIC5365 does not. Substituting one for the other may cause unintended output discharge behavior in systems relying on controlled ramp-down.
What is the thermal resistance (θJA) of the MIC5365-2.6YC5-TR in its SC-70-5 package?
The junction-to-ambient thermal resistance (θJA) for the MIC5365-2.6YC5-TR in SC-70-5 package is 256.5°C/W under standard JEDEC test conditions. This value assumes a two-layer PCB with 1in² copper pour on both sides; actual θJA improves with enhanced copper area or thermal vias beneath the exposed pad (though the SC-70-5 variant has no thermal pad).
Can the MIC5365-2.6YC5-TR be used without connecting the EN pin?
No - the EN pin of the MIC5365-2.6YC5-TR must not be left floating. It is an active-high CMOS input with defined logic thresholds (VIH ≥ 1.2V, VIL ≤ 0.2V). An unconnected EN pin may result in indeterminate output state or erratic enable behavior. Tie EN directly to VIN for always-on operation or to a microcontroller GPIO for controlled sequencing.
