Product details
Overview
MIC5365-2.7YC5-TR from Micrel is a fixed-output 2.7V, 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 PMPs.
For engineers reviewing the MIC5365-2.7YC5-TR datasheet, MIC5365-2.7YC5-TR pinout, MIC5365-2.7YC5-TR application, or MIC5365-2.7YC5-TR equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, application-specific use cases, and two confirmed alternative parts with functional and packaging distinctions.
Technical Context
The MIC5365-2.7YC5-TR is a CMOS-based fixed-output LDO with active-high enable control, thermal shutdown, and current limiting. It operates across 2.5V–5.5V input range and maintains regulation down to 0mA load without external compensation.
Its architecture supports stable operation with only 1µF ceramic output capacitance (X5R/X7R), achieves 70dB PSRR up to 1kHz, and enters near-zero-off-mode (<1µA) when EN is pulled low - critical for battery runtime extension in intermittent-use devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.7V ±2% (initial), ±3% over –40°C to +125°C - ensures reliable logic-level supply for 2.7V I/O domains. |
| Max Output Current | 150mA guaranteed - sufficient to power baseband processors or RF front-end ICs in compact portable designs. |
| Dropout Voltage | 155mV @ 150mA - enables operation from single-cell Li-ion (3.0V min) while retaining ≥2.55V output under full load. |
| Quiescent Current | 29µA typical - minimizes standby power loss in always-on subsystems like RTC or sensor wake-up circuits. |
| PSRR | 70dB @ 1kHz - suppresses switching noise from adjacent DC/DC converters, preserving analog signal integrity. |
| Enable Threshold | Logic-high ≥1.2V, logic-low ≤0.2V - compatible with 1.8V/3.3V GPIO without level-shifting. |
| Thermal Shutdown | Active at TJ ≥150°C - protects device during transient overload or poor PCB thermal layout. |
Pinout & Package
SC-70-5 package (5-pin, 2.0mm × 1.25mm × 0.95mm height), RoHS-compliant, Pb-free NiPdAu finish. Exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main power input (2.5V–5.5V); requires 1µF X5R/X7R ceramic bypass capacitor to GND. |
| 2 | GND | Analog/digital ground reference; must connect directly to low-impedance PCB ground plane. |
| 3 | EN | Active-high enable: >1.2V = ON, <0.2V = OFF; floating prohibited - tie to VIN or MCU GPIO. |
| 4 | VOUT | Regulated 2.7V output; stable with ≥1µF ceramic capacitor; no-load regulation supported. |
| 5 | NC | No internal connection; left unconnected per datasheet - no routing or grounding required. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | SC-70-5 occupies 2.5mm² PCB area - 75% smaller than legacy SOT-23, enabling high-density portable layouts. |
| Low-noise regulation | 200µVRMS (10Hz–100kHz) - suitable for powering ADC references or RF synthesizer VCOs without added filtering. |
| Zero-off-mode current | <1µA shutdown current - extends battery life in sleep states of GPS trackers or wearable sensors. |
| Robust protection | Integrated thermal shutdown and foldback current limiting - eliminates need for external fault management circuitry. |
| Capacitor flexibility | Stable with 1µF X5R/X7R ceramic output cap - avoids costly tantalum or large-case ceramics in space-constrained designs. |
Applications
| GPS Module Power Supply | Digital Camera Sensor Bias |
|---|---|
|
Use Scenario: Powers GPS baseband processor and RF front-end in ultra-thin wearables where board area and battery life are constrained. IC Role / Device Role / Timing Role: Primary 2.7V LDO supplying core logic and RF section; enables fast EN-controlled wake-up from deep sleep.

Use Scenario: Supplies image sensor analog bias rails in compact digital cameras requiring low-noise, stable voltage under dynamic load. IC Role / Device Role / Timing Role: Low-noise 2.7V source for CIS analog blocks; PSRR >70dB prevents switching noise coupling into pixel data path. Use Value: 200µVRMS output noise meets sensor SNR requirements without adding ferrite beads or LC filters. |
| Handheld PMP Audio Codec | Industrial Handheld Scanner Logic |
|
Use Scenario: Powers audio codec's digital core and PLL in portable media players where EMI sensitivity and standby current matter. IC Role / Device Role / Timing Role: Dedicated 2.7V rail for codec logic; EN pin synchronized with playback state to minimize idle consumption. Use Value: 29µA quiescent current reduces average system standby draw by ~15µA versus standard 100µA LDOs. |
Use Scenario: Supplies microcontroller I/O bank and display driver in ruggedized industrial scanners operating across –40°C to +85°C ambient. IC Role / Device Role / Timing Role: Temperature-stable 2.7V source; ±3% accuracy over full range ensures reliable logic-level margin at temperature extremes. Use Value: Guaranteed 150mA output sustains peak burst current during laser trigger and Bluetooth transmission without brownout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-2702E/TT | 250mA rated, 1.6µA quiescent current, SOT-23-3 package (no EN pin) | Lacks enable control and has lower max current; suited for simpler always-on rails | Select when ultra-low IQ dominates over programmability and 150mA headroom. |
| Torex XC6206P272MR-G | 150mA rated, 1µA IQ, SOT-23-5 with EN, but ±3% accuracy and 300mV dropout @150mA | Higher dropout limits usable input range; less precise output affects 2.7V-tolerant logic margins | Choose only if 1µA shutdown current is mandatory and 2.55V minimum output is acceptable. |
Compared with MCP1700T-2702E/TT and XC6206P272MR-G, the MIC5365-2.7YC5-TR uniquely balances 150mA drive, 29µA IQ, ±2% accuracy, and 155mV dropout in SC-70-5 - making it optimal for space-constrained, battery-powered systems needing both precision and efficiency.

FAQ
What is the maximum input voltage for MIC5365-2.7YC5-TR?
The MIC5365-2.7YC5-TR supports an absolute maximum input voltage of 6V, but its recommended operating range is 2.5V to 5.5V. Operating above 5.5V risks exceeding absolute maximum ratings and may trigger thermal shutdown or permanent damage. Always maintain VIN within the specified operating range for reliable long-term performance of the MIC5365-2.7YC5-TR.
Does MIC5365-2.7YC5-TR require an external output capacitor?
Yes, the MIC5365-2.7YC5-TR requires a minimum 1µF ceramic output capacitor (X5R or X7R dielectric) for stability. The datasheet confirms stable operation with this value and warns against Y5V/Z5U types due to severe capacitance loss over temperature. Larger values do not improve performance significantly - the MIC5365-2.7YC5-TR is optimized for 1µF.
Is MIC5365-2.7YC5-TR pin-compatible with MIC5366-2.7YC5-TR?
No, MIC5365-2.7YC5-TR is not pin-compatible with MIC5366-2.7YC5-TR. While both share the same SC-70-5 package and pin numbering, the MIC5366 variant integrates an auto-discharge NFET on the VOUT pin (pin 4), which alters the internal connection and behavior during shutdown. Using them interchangeably may cause unintended discharge paths or startup issues - the MIC5365-2.7YC5-TR lacks this feature entirely.
What is the thermal resistance (θJA) of MIC5365-2.7YC5-TR in SC-70-5 package?
The junction-to-ambient thermal resistance (θJA) for MIC5365-2.7YC5-TR in SC-70-5 package is 256.5°C/W, as specified in the Absolute Maximum Ratings table. This value assumes standard JEDEC 2-layer board conditions; actual θJA improves with enhanced copper pour or thermal vias. For 150mA load at 2.7V output from 3.6V input, power dissipation is ~135mW, resulting in ~34.5°C junction rise above ambient - well within the –40°C to +125°C operating range of the MIC5365-2.7YC5-TR.
Can MIC5365-2.7YC5-TR be used without connecting the NC pin?
Yes, pin 5 of MIC5365-2.7YC5-TR is explicitly designated "NC" (No Connect) in the Pin Description table and must remain unconnected - no routing, grounding, or pulling is permitted. It is not internally bonded and serves no electrical function. Connecting it may introduce parasitic leakage or contamination risk; leaving it floating per datasheet instruction ensures correct operation of the MIC5365-2.7YC5-TR.
