Product details
Overview
MIC5365-2.8YD5-TR from Micrel is a fixed-output 2.8V, 150mA low-dropout linear regulator in a 5-pin TSOT23 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 MIC5365-2.8YD5-TR datasheet, MIC5365-2.8YD5-TR pinout, MIC5365-2.8YD5-TR application, or MIC5365-2.8YD5-TR equivalent, key selection criteria include its 2.5V–5.5V input range, thermal shutdown protection, stable operation with 1µF ceramic output capacitors, and zero-off-mode current draw when disabled via active-high EN pin.
Technical Context
The MIC5365-2.8YD5-TR employs a CMOS-based pass element with internal compensation, enabling stable regulation without external components beyond 1µF input/output ceramics. Its enable logic uses CMOS-level thresholds (VIH ≥ 1.2V, VIL ≤ 0.2V), and it features built-in thermal shutdown and foldback current limiting.
Unlike the MIC5366 variant, this part lacks auto-discharge functionality. It operates across –40°C to +125°C junction temperature and achieves 70dB PSRR up to 1kHz, making it suitable for noise-sensitive analog and RF subsystems powered from shared battery rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8V ±2% initial accuracy ensures reliable biasing of 2.8V I/O domains or low-voltage microcontrollers. |
| Max Output Current | 150mA guaranteed - sufficient for powering single-core MCUs, sensors, or RF front-end ICs in compact portable designs. |
| Dropout Voltage | 155mV @ 150mA - enables operation from 2.955V minimum input, supporting deep battery discharge down to ~3.0V nominal Li-ion. |
| Quiescent Current | 29µA typical - minimizes standby power loss in always-on monitoring circuits or real-time clock keep-alive paths. |
| PSRR | 70dB @ 1kHz - suppresses switching noise from adjacent DC/DC converters, preserving signal integrity in mixed-signal systems. |
| Input Voltage Range | 2.5V to 5.5V - compatible with single-cell Li-ion (2.7–4.2V), LiFePO₄ (2.0–3.6V), and 3.3V/5V system rails. |
| Thermal Protection | Integrated thermal shutdown - prevents damage during sustained overload or poor PCB heat sinking in sealed enclosures. |
Pinout & Package
Package: 5-Pin TSOT23 (Thin Small Outline Transistor), RoHS-compliant, 1.6mm × 2.9mm footprint, exposed pad for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main supply input; must be decoupled with ≥1µF ceramic capacitor close to pin to ensure stability and transient response. |
| 2 | GND | Power ground reference; connects directly to PCB ground plane and exposed thermal pad for optimal thermal performance. |
| 3 | EN | Active-high enable control; requires pull-up or direct logic drive; floating state is undefined and must be avoided. |
| 4 | VOUT | Regulated 2.8V output; requires ≥1µF low-ESR ceramic capacitor to maintain loop stability and reduce output ripple. |
| 5 | NC | No connect; not internally bonded - electrically isolated and may be left unconnected or tied to GND for mechanical reinforcement only. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 29µA typical - extends battery life in always-on sensor nodes and wearable devices operating for months on coin cells. |
| Stable with minimal capacitance | Works reliably with 1µF ceramic output capacitor - reduces BOM count and board area versus regulators requiring ≥10µF tantalum. |
| High PSRR at audio frequencies | 70dB rejection up to 1kHz - mitigates noise coupling from PMICs or buck converters into ADC references or audio codecs. |
| Robust fault protection | Thermal shutdown + current limiting - eliminates need for external reset supervisors or fuses in space-constrained consumer designs. |
| Wide input voltage range | 2.5V–5.5V operation - supports direct connection to USB VBUS, Li-ion batteries, or legacy 3.3V/5V rails without pre-regulation. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-2802E/TO | 250mA rated, 1.6µA quiescent current, but only 60dB PSRR @ 1kHz and no thermal shutdown. | Suitable for ultra-low-power sensor nodes where PSRR and fault protection are secondary to standby current. | Select when sub-2µA IQ dominates design requirements and load current stays below 100mA. |
| Torex XC6206P282MR-G | 150mA rated, 1µA IQ, ±2% accuracy, but 300mV dropout @ 150mA and no enable pin. | Fits simple always-on applications like RTC backup supplies where disable control is unnecessary. | Choose for cost-sensitive, non-enabling applications needing lowest possible IQ and acceptable dropout margin. |
Compared with MCP1700-2802E/TO and XC6206P282MR-G, the MIC5365-2.8YD5-TR delivers superior PSRR and integrated thermal/current protection at the expense of slightly higher quiescent current - making it the preferred choice for noise-critical, safety-aware portable systems requiring robustness over extreme ultra-low-power operation.

FAQ
What is the maximum input voltage rating for the MIC5365-2.8YD5-TR?
The MIC5365-2.8YD5-TR has an absolute maximum input voltage rating of 6V, but its specified operating input range is 2.5V to 5.5V. Exceeding 5.5V risks violating functional specifications and may trigger internal protection mechanisms. For reliable long-term operation, VIN should remain within the 2.5V–5.5V window per the datasheet's Operating Ratings table.
Does the MIC5365-2.8YD5-TR include auto-discharge functionality?
No, the MIC5365-2.8YD5-TR does not include auto-discharge. That feature is exclusive to the MIC5366 variant (e.g., MIC5366-2.8YD5). When the MIC5365-2.8YD5-TR is disabled via the EN pin, the output floats - external discharge circuitry is required if rapid VOUT decay is needed after shutdown.
Can the MIC5365-2.8YD5-TR operate without an output capacitor?
No - the MIC5365-2.8YD5-TR requires a minimum 1µF ceramic output capacitor for stability, as confirmed in the Application Information section. Omitting it risks oscillation, poor transient response, and potential damage under load. X5R or X7R dielectrics are recommended; Y5V types are explicitly discouraged due to severe capacitance loss over temperature.
What is the thermal resistance (θJA) of the MIC5365-2.8YD5-TR package?
The MIC5365-2.8YD5-TR uses a 5-pin TSOT23 package with a junction-to-ambient thermal resistance (θJA) of 253°C/W, as specified in the Electrical Characteristics table. This value assumes standard JEDEC 2-layer board conditions; actual θJA improves with PCB copper area, thermal vias to inner ground planes, and connection of the exposed pad to GND.
Is the MIC5365-2.8YD5-TR RoHS-compliant and lead-free?
Yes, the MIC5365-2.8YD5-TR is RoHS-compliant and lead-free, with a NiPdAu lead finish. This is explicitly stated in the Ordering Information table and Package Information section of the datasheet, confirming compliance with EU Directive 2011/65/EU and related environmental standards.
