Product details
Overview
MIC5365-2.0YC5-TR from Micrel is a fixed-output 2.0V, 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 space-constrained portable electronics requiring stable low-voltage biasing of RF ICs or memory retention circuits.
For engineers reviewing the MIC5365-2.0YC5-TR datasheet, MIC5365-2.0YC5-TR pinout, MIC5365-2.0YC5-TR application, or MIC5365-2.0YC5-TR equivalent, key selection criteria include its 2.5V–5.5V input range, SC-70-5 thermal resistance (256.5°C/W), zero-off-mode shutdown behavior, and compatibility with 1µF ceramic output capacitors without external compensation.
Technical Context
The MIC5365-2.0YC5-TR implements a CMOS-based LDO architecture with active-high enable control and internal thermal shutdown/current limit protection. It operates across –40°C to +125°C junction temperature and maintains regulation down to zero load.
Unlike MIC5366 variants, this part lacks auto-discharge functionality; its enable pin (EN) controls only ON/OFF state, not output discharge. Stability is guaranteed with ≥1µF X5R/X7R ceramic output capacitance and requires no external feedback network due to fixed internal voltage reference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.0V ±2% (initial), ±3% over –40°C to +125°C - ensures precise core/bias rail for 2.0V logic or analog subsystems. |
| Max Output Current | 150mA guaranteed - supports moderate-current peripherals like sensors, small displays, or RF front-end biasing. |
| Dropout Voltage | 155mV @ 150mA - enables operation from 2.155V minimum input, critical for single-cell Li-ion or coin-cell applications. |
| Quiescent Current | 29µA typical - minimizes standby power loss in battery-backed systems such as real-time clocks or memory keep-alive circuits. |
| PSRR | 70dB @ 1kHz - suppresses supply noise from noisy DC-DC converters feeding sensitive analog or RF circuitry. |
| Input Voltage Range | 2.5V to 5.5V - compatible with common intermediate rails (3.3V, 5V) and higher-voltage battery inputs with sufficient headroom. |
| Enable Threshold | Logic high ≥1.2V, logic low ≤0.2V - interfaces directly with 1.8V/3.3V GPIO without level-shifting. |
Pinout & Package
SC-70-5 package: 1.25mm × 1.75mm footprint, 0.65mm pitch, exposed pad not present. Thermal resistance θJA = 256.5°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main power input; must be decoupled with ≥1µF ceramic capacitor close to pin. |
| 2 | GND | Analog/digital ground reference; connects to PCB ground plane for thermal and noise performance. |
| 3 | EN | Active-high enable; must be pulled high (≥1.2V) to activate regulator; floating state is undefined and prohibited. |
| 4 | VOUT | Regulated 2.0V output; requires ≥1µF X5R/X7R ceramic capacitor to ground for stability. |
| 5 | NC | No internal connection; left unconnected per datasheet - no routing or grounding required. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small SC-70-5 footprint | 1.25mm × 1.75mm area - saves >75% board space vs. SOT-23 while maintaining manufacturability. |
| Zero-off-mode shutdown | 0.05µA max ground current when EN ≤ 0.2V - eliminates battery drain during system sleep states. |
| Stable with 1µF ceramic output cap | No ESR requirements or external compensation needed - simplifies BOM and layout for cost-sensitive designs. |
| High PSRR (70dB) | Rejects switching noise from upstream DC-DC converters - preserves signal integrity in mixed-signal SoC power domains. |
| Full protection suite | Thermal shutdown and foldback current limiting - prevents damage during overload or ambient temperature excursions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-2002E/TT | 2.0V fixed, 250mA rated, 1.6µA quiescent current, SOT-23-5 package | Lower IQ enables ultra-low-power applications; higher current rating suits future-proofing but larger package (SOT-23 vs SC-70) | Select when <2µA shutdown current is mandatory and board area permits SOT-23 footprint. |
| Torex XC6206P202MR-G | 2.0V fixed, 150mA, 1µA IQ, SOT-23-5, no enable pin | Eliminates enable control complexity but removes software-controlled power gating capability | Select for simple always-on bias rails where enable functionality is unnecessary and sub-µA IQ is critical. |
Compared with MCP1700T-2002E/TT and XC6206P202MR-G, the MIC5365-2.0YC5-TR uniquely balances ultra-small SC-70-5 size, 29µA IQ, and active enable control - making it optimal for space-limited portable systems requiring both low standby power and firmware-managed power sequencing.

FAQ
What is the maximum input voltage rating for the MIC5365-2.0YC5-TR?
The MIC5365-2.0YC5-TR has an absolute maximum input voltage of 6V, but its recommended operating input range is 2.5V to 5.5V. Exceeding 5.5V may trigger internal protection or cause reliability degradation. For sustained operation, maintain VIN within this specified range to ensure compliance with electrical characteristics including dropout and PSRR performance.
Does the MIC5365-2.0YC5-TR include an auto-discharge feature?
No, the MIC5365-2.0YC5-TR does not include auto-discharge functionality. That feature is exclusive to MIC5366-series variants (e.g., MIC5366-2.0YC5*). The MIC5365-2.0YC5-TR disables output when EN is low but leaves VOUT floating - external discharge circuitry is required if rapid output decay is needed after shutdown.
Can the MIC5365-2.0YC5-TR operate stably with no load?
Yes, the MIC5365-2.0YC5-TR remains stable and in regulation with zero load current - a key design feature confirmed in the datasheet's Application Information section. This makes it suitable for memory keep-alive, RTC backup, or other always-on low-power functions where load current may drop to zero during system sleep.
What output capacitor type and value are required for stability with the MIC5365-2.0YC5-TR?
The MIC5365-2.0YC5-TR requires a minimum 1µF ceramic output capacitor with X5R or X7R dielectric. Y5V and Z5U types are explicitly discouraged due to excessive capacitance drift over temperature. Larger values (e.g., 2.2µF) are acceptable but provide no significant performance improvement beyond the 1µF baseline validated in the datasheet.
Is the NC pin on the MIC5365-2.0YC5-TR required to be grounded or left floating?
The NC (No Connect) pin on the MIC5365-2.0YC5-TR must remain unconnected - it has no internal connection and serves no electrical function. Grounding or routing this pin violates the datasheet specification and may compromise thermal performance or introduce unintended coupling paths in high-frequency layouts.
