Product details
Overview
MIC5365-2.85YD5-T5 from Micrel is a fixed-output 2.85V, 150mA low-dropout linear regulator in a 5-pin TSOT23 package, featuring 2% initial output accuracy, 155mV dropout at full load, and 29µA quiescent current - optimized for space-constrained portable electronics requiring stable low-noise power delivery.
For engineers reviewing the MIC5365-2.85YD5-T5 datasheet, MIC5365-2.85YD5-T5 pinout, MIC5365-2.85YD5-T5 application, or MIC5365-2.85YD5-T5 equivalent, this page delivers verified specifications, thermal performance data, enable logic behavior, PCB layout guidance for TSOT23-5, and real-world substitution options with documented functional distinctions.
Technical Context
The MIC5365-2.85YD5-T5 implements a CMOS-based LDO architecture with active-high enable control, internal current limiting (200–550mA), and thermal shutdown protection. It operates across 2.5V–5.5V input range and maintains regulation down to zero load.
Its high PSRR (70dB up to 1kHz) and low output noise (200µVRMS, 10Hz–100kHz) stem from bandwidth-optimized internal compensation, enabling stable operation with only 1µF ceramic input and output capacitors - no external compensation required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.85V ±2% (initial), ±3% over –40°C to +125°C - ensures consistent biasing for 2.8V–3.0V logic rails. |
| Max Output Current | 150mA guaranteed - supports moderate-power RF modules, sensors, and microcontroller peripherals without derating. |
| Dropout Voltage | 155mV @ 150mA (VOUT ≥ 2.8V) - enables operation from 3.0V supply while delivering 2.85V output. |
| Quiescent Current | 29µA typical - extends battery life in always-on keep-alive circuits like RTC or SRAM backup. |
| PSRR | 70dB @ 1kHz - suppresses switching noise from adjacent DC/DC converters feeding shared input rails. |
| Enable Threshold | Logic high ≥1.2V, logic low ≤0.2V - compatible with 1.8V/3.3V GPIO without level-shifting. |
| Thermal Resistance | θJA = 253°C/W (TSOT23-5) - limits max ambient temperature to ~95°C at 150mA with 3.6V→2.85V drop. |
Pinout & Package
Package: 5-Pin TSOT23 (Thin Small Outline Transistor), RoHS-compliant, Pb-free, 1.6mm × 2.9mm footprint, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Supply Input | Accepts 2.5V–5.5V; requires 1µF X5R/X7R ceramic capacitor to ground for stability. |
| 2 - GND | Ground Reference | Primary return path for load and quiescent current; connects to PCB ground plane under exposed pad. |
| 3 - EN | Enable Input | Active-high CMOS input; must be pulled high (>1.2V) to enable output; floating state prohibited. |
| 4 - NC | No Connect | Internally unconnected; no electrical function - leave unpopulated or grounded per layout best practice. |
| 5 - VOUT | Regulated Output | Delivers fixed 2.85V; requires 1µF ceramic capacitor to ground; stable with zero load. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small TSOT23-5 package | 1.6mm × 2.9mm footprint - reduces PCB area by >60% vs. standard SOT23-5, ideal for compact handhelds. |
| Zero-off-mode shutdown | 0.05µA max ground current when EN ≤ 0.2V - eliminates standby leakage in battery-critical systems. |
| Capacitor-stable design | Stable with 1µF ceramic CIN/COUT - eliminates need for large or specialized capacitors, lowering BOM cost. |
| High-accuracy output | ±2% initial tolerance - avoids post-production trimming and simplifies voltage-margin testing. |
| Robust fault protection | Integrated thermal shutdown and foldback current limiting - prevents damage during short-circuit or overload. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-285T50I/OT | 300mA rated, 1.6µA IQ, but 600mV dropout @ 250mA - higher dropout and lower max current than MIC5365-2.85YD5-T5. | Suitable for ultra-low-IQ applications with light loads (<50mA); less suitable for 150mA continuous use with tight input headroom. | Select when lowest possible quiescent current dominates over load capability and dropout. |
| Torex XC6206P285MR-G | 150mA rated, 1µF min COUT, but only 45dB PSRR @ 1kHz and ±3% output accuracy - lower noise rejection and looser tolerance. | Better for cost-sensitive consumer wearables where PSRR and accuracy margins are relaxed. | Select when budget constraints outweigh need for high PSRR and tight voltage regulation. |
Compared with MCP1700-285T50I/OT and XC6206P285MR-G, the MIC5365-2.85YD5-T5 delivers superior PSRR and tighter initial accuracy at the expense of slightly higher quiescent current - making it optimal for noise-sensitive, medium-current portable applications where regulation stability is critical.

FAQ
What is the maximum input voltage rating for the MIC5365-2.85YD5-T5?
The MIC5365-2.85YD5-T5 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. The device is commonly used with 3.3V or 3.6V Li-ion battery inputs, where the 155mV dropout ensures reliable 2.85V output delivery even under battery discharge conditions.
Does the MIC5365-2.85YD5-T5 require an output capacitor, and what type is recommended?
Yes, the MIC5365-2.85YD5-T5 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 dielectrics are discouraged due to excessive capacitance loss over temperature. The regulator remains stable with zero load, eliminating need for dummy loads in low-power sleep modes.
Is the MIC5365-2.85YD5-T5 pin-compatible with the MIC5366-2.85YD5-T5?
No - the MIC5365-2.85YD5-T5 lacks the auto-discharge NFET present in the MIC5366 variant. While both share identical pinout and basic regulation specs, the MIC5366 actively discharges the output when disabled (EN = low), whereas the MIC5365-2.85YD5-T5 leaves VOUT floating. This functional difference affects system-level power sequencing and cannot be interchanged without circuit review.
What is the thermal performance of the MIC5365-2.85YD5-T5 in its TSOT23-5 package?
The MIC5365-2.85YD5-T5 has a junction-to-ambient thermal resistance (θJA) of 253°C/W in the TSOT23-5 package. At 150mA load with 3.6V input and 2.85V output, power dissipation is ~113mW, resulting in a junction temperature rise of ~28.6°C above ambient. With a max TJ of 125°C, this allows safe operation up to ~96°C ambient - assuming standard 2-layer PCB with minimal copper pour.
Can the MIC5365-2.85YD5-T5 be used without an enable signal tied to a controller?
No - the EN pin must not be left floating. It is an active-high CMOS input requiring a defined logic level: tie to VIN through a pull-up resistor (e.g., 100kΩ) if always-on operation is needed, or drive directly from a GPIO. A floating EN pin may cause erratic output behavior or unintended shutdown due to noise coupling, as confirmed in the datasheet's "Enable/Shutdown" section.
