Product details
Overview
MIC5365-2.8YD5-T5 from Micrel is a fixed-output 2.8V, 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. It operates from 2.5V to 5.5V input and delivers stable power to noise-sensitive RF and portable logic circuits.
For engineers reviewing the MIC5365-2.8YD5-T5 datasheet, MIC5365-2.8YD5-T5 pinout, MIC5365-2.8YD5-T5 application, or MIC5365-2.8YD5-T5 equivalent, key selection criteria include ultra-low ground current in shutdown (≤1µA), compatibility with 1µF ceramic output capacitors, high PSRR (70dB), and active-high enable control for battery-powered system power sequencing.
Technical Context
The MIC5365-2.8YD5-T5 implements a CMOS-based LDO architecture with internal P-channel pass transistor, enabling low dropout and minimal quiescent current across load and temperature. Its feedback loop is optimized for stability with 1µF X5R/X7R ceramic output capacitors without requiring ESR tuning.
It features an active-high enable input (VIH ≥ 1.2V, VIL ≤ 0.2V) that places the device into zero-off-mode current state (<1µA) when disabled, and includes thermal shutdown and foldback current limiting for fault protection. No auto-discharge circuit - that function is exclusive to MIC5366 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8V ±2% initial accuracy; ensures tight supply rail tolerance for 2.8V I/O or core logic without external feedback. |
| Max Output Current | 150mA guaranteed; supports moderate-power microcontrollers, sensors, or RF front-end ICs in compact portable designs. |
| Dropout Voltage | 155mV @ 150mA; enables operation down to VIN = 2.955V while maintaining regulation - critical for single-cell Li-ion or Li-poly systems. |
| Quiescent Current | 29µA typical @ 100µA load; minimizes standby power loss in always-on subsystems like real-time clocks or wake-up controllers. |
| PSRR | 70dB @ 1kHz; suppresses switching noise from upstream DC/DC converters, preserving signal integrity in ADCs and RF receivers. |
| Input Voltage Range | 2.5V to 5.5V; compatible with common battery chemistries (Li-ion, LiFePO₄, 3×NiMH) and regulated 3.3V/5V rails. |
| Operating Temp | –40°C to +125°C junction; qualified for automotive cabin, industrial edge nodes, and extended-temperature portable equipment. |
Pinout & Package
Package: 5-Pin TSOT23 (Thin Small Outline Transistor), 1.6mm × 2.9mm × 0.95mm body height, RoHS-compliant NiPdAu lead finish, exposed heatsink pad (EP) for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main power input; must be decoupled with ≥1µF ceramic capacitor close to pin to ensure stability and transient response. |
| 2 | GND | Analog/digital ground reference; connects directly to PCB ground plane; ties to EP for optimal thermal performance. |
| 3 | EN | Active-high enable; requires pull-up or controlled logic drive; floating state is prohibited and may cause erratic output behavior. |
| 4 | VOUT | Regulated 2.8V output; requires ≥1µF low-ESR ceramic capacitor to ground for loop stability and noise filtering. |
| 5 | NC | No connect; not internally bonded; must remain unconnected on PCB to avoid parasitic coupling or reliability risk. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | TSOT23-5 package occupies <2.5mm² PCB area - 75% smaller than legacy SOT23-5, enabling dense portable layouts. |
| Capacitor-compatible stability | Stable with 1µF X5R/X7R ceramic output caps only - eliminates need for ESR-tuned tantalum or aluminum electrolytics. |
| Zero-off-mode shutdown | Draws ≤1µA when EN = low - extends battery life in sleep modes of wearables and IoT endpoints. |
| High-accuracy output | ±2% initial tolerance and ±3% over –40°C to +125°C - reduces need for post-regulation trimming in production test. |
| Fault protection | Integrated thermal shutdown and current limiting - prevents damage during short-circuit or overload conditions without external components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-2802E/TT | 100mA max output, 6µA quiescent current, 1.6V–6.0V input range; smaller 3-pin SOT23 package. | Lower current capability limits use to ultra-low-power MCUs or sensors; better suited for sub-50mA always-on monitoring. | Select when minimizing standby current is primary and load current never exceeds 100mA. |
| Torex XC6206P282MR-G | 150mA output, 3µA quiescent current, 1.8V–6.0V input; SOT23-5 package, ±2% accuracy, but no enable pin. | Fixed-on operation only - unsuitable for systems requiring dynamic power gating or multi-rail sequencing. | Select when enable control is unnecessary and lowest possible quiescent current dominates design priorities. |
Compared with MCP1700T-2802E/TT and XC6206P282MR-G, the MIC5365-2.8YD5-T5 uniquely balances 150mA drive, 29µA IQ, and active-high enable in a thermally enhanced TSOT23 - making it optimal for portable systems needing both performance headroom and intelligent power management.

FAQ
What is the maximum input voltage rating for the MIC5365-2.8YD5-T5?
The MIC5365-2.8YD5-T5 has an absolute maximum input voltage of 6V, but its recommended operating input range is 2.5V to 5.5V. Exceeding 5.5V risks violating safe operating area limits and may trigger thermal shutdown or permanent damage. For reliable long-term operation, maintain VIN ≤ 5.5V with appropriate derating margin per application ambient conditions.
Does the MIC5365-2.8YD5-T5 include an auto-discharge function?
No, the MIC5365-2.8YD5-T5 does not include an auto-discharge function. That feature is exclusive to the MIC5366 series (e.g., MIC5366-2.8YD5). The MIC5365-2.8YD5-T5 lacks the internal NFET discharge path; when disabled, its output floats and discharges only through external load or board leakage paths.
Can the MIC5365-2.8YD5-T5 operate without an output capacitor?
No - the MIC5365-2.8YD5-T5 requires a minimum 1µF ceramic output capacitor (X5R or X7R dielectric) for stability. Omitting it causes oscillation and output voltage collapse. Unlike some older LDOs, this device is not no-load stable without COUT; the capacitor also improves transient response and PSRR performance.
What is the thermal resistance (θJA) of the MIC5365-2.8YD5-T5 in its TSOT23-5 package?
The junction-to-ambient thermal resistance (θJA) for the MIC5365-2.8YD5-T5 in the 5-pin TSOT23 package is 253°C/W, measured under standard JEDEC PCB conditions (2s2p copper layers). With proper PCB copper pour under the exposed pad (EP), actual θJA can improve to ~120–150°C/W, enabling higher continuous current in thermally constrained layouts.
Is the MIC5365-2.8YD5-T5 pin-compatible with other members of the MIC5365 family?
Yes - all MIC5365 variants in the TSOT23-5 (YD5) package share identical pinout: Pin 1 = VIN, Pin 2 = GND, Pin 3 = EN, Pin 4 = VOUT, Pin 5 = NC. Voltage variants (e.g., MIC5365-1.8YD5, MIC5365-3.3YD5) are electrically and mechanically interchangeable on the same footprint, simplifying BOM consolidation and design reuse.
