Product details
Overview
MIC5363-2.8YMT from Micrel is a fixed 2.8V, 300mA low-dropout linear regulator with ±2% output accuracy, 70dB PSRR at 1kHz, and 225mV dropout at full load-designed for noise-sensitive portable electronics such as camera DSP power supplies.
For engineers reviewing the MIC5363-2.8YMT datasheet, MIC5363-2.8YMT pinout, MIC5363-2.8YMT application, or MIC5363-2.8YMT equivalent, key selection criteria include input voltage range (2.5–5.5V), ultra-low quiescent current (38µA typ), stability with 1µF ceramic capacitors, thermal shutdown, and compatibility with 1.2mm × 1.2mm Thin MLF® layout constraints.
Technical Context
The MIC5363-2.8YMT employs a P-channel pass transistor architecture enabling low dropout and high PSRR via fast error amplifier response. It integrates internal feedback resistors and a precision bandgap reference to maintain ±2% output accuracy across –40°C to +125°C.
No active discharge circuit is present-this feature is exclusive to the MIC5364 variant. The device operates with CMOS-level enable logic (active-high EN), requires no minimum load, and achieves stable regulation using only 1µF input and output ceramic capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8V ±2% over temperature and load-ensures consistent biasing for downstream analog/RF stages. |
| Max Output Current | 300mA continuous-supports moderate-power digital cores or sensor interfaces without external boost. |
| Dropout Voltage | 225mV at 300mA-enables operation from 3.025V input when VOUT = 2.8V, extending battery runtime. |
| PSRR | 70dB @ 1kHz-rejects switching noise from adjacent DC-DC converters in compact PCB layouts. |
| Quiescent Current | 38µA typical-minimizes standby power loss in always-on subsystems like real-time clocks or wake-up monitors. |
| Input Voltage Range | 2.5V to 5.5V-compatible with single-cell Li-ion (2.7–4.2V), USB-powered, and dual-cell alkaline inputs. |
| Thermal Shutdown | Active protection at +125°C junction-prevents damage during transient overload or poor heatsinking. |
Pinout & Package
Package: 6-pin 1.2mm × 1.2mm Thin MLF® with exposed ePad (EP) for thermal conduction to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | N/C | No internal connection-must remain unconnected; no routing or soldering required. |
| 3 | GND | Power ground reference and return path for all internal circuits; connect directly to solid ground plane. |
| 4 | VIN | Main supply input; decouple with 1µF X5R/X7R ceramic capacitor placed ≤2mm from pin. |
| 5 | VOUT | Regulated 2.8V output; decouple with 1µF ceramic capacitor; supports zero-load stability. |
| 6 | EN | Active-high enable control; logic HIGH ≥1.2V enables regulation; must not float-tie to VIN or microcontroller GPIO. |
| EP | ePad | Exposed thermal pad; electrically and thermally connected to GND for optimal θJA (173°C/W) and reliability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 1.2mm × 1.2mm Thin MLF® package saves >60% board area vs. SOT-23, critical for camera modules and wearables. |
| Low-noise regulation | 200µVRMS output noise (10Hz–100kHz) preserves signal integrity in ADC references and RF front-ends. |
| Fast transient response | 60–150µs turn-on time ensures rapid power-up of digital peripherals without brownout risk. |
| Robust protection | Integrated thermal shutdown and current limiting prevent latch-up or destruction under short-circuit or overtemperature conditions. |
| Capacitor flexibility | Stable with 1µF ceramic capacitors (X5R/X7R); eliminates need for bulky tantalum or electrolytic types. |

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 max output, 6µA quiescent current, TO-92 package (larger footprint, higher θJA) | Lower current capability; suited for ultra-low-power sensors but not camera DSP loads | Select if standby current is priority over output current and board space is unconstrained. |
| Torex XC6206P282MR-G | 300mA output, 1µF min COUT, but only 50dB PSRR @1kHz and ±3% accuracy | Higher output tolerance and lower noise rejection limit use in precision analog rails | Choose for cost-sensitive consumer devices where PSRR >60dB is not required. |
Compared with MCP1700-2802E/TO and XC6206P282MR-G, the MIC5363-2.8YMT delivers superior PSRR (70dB), tighter accuracy (±2%), and smaller footprint-making it optimal for space-constrained, noise-sensitive portable designs demanding 300mA.

FAQ
What is the maximum input voltage for MIC5363-2.8YMT?
The MIC5363-2.8YMT supports an absolute maximum input voltage of +6V, but its recommended operating range is +2.5V to +5.5V. Exceeding 5.5V may trigger internal protection or degrade long-term reliability. For a 2.8V output, the practical upper limit is determined by thermal limits-e.g., at 300mA load and 3.6V input, power dissipation is ~0.24W, allowing safe operation up to 83°C ambient in standard layout. Always observe the 173°C/W θJA rating.
Does MIC5363-2.8YMT include an auto-discharge function?
No, the MIC5363-2.8YMT does not include an auto-discharge function. That feature is exclusive to the MIC5364 variant (e.g., MIC5364-2.8YMT), which integrates a 30Ω NFET between VOUT and GND to actively discharge output capacitors when disabled. The MIC5363-2.8YMT relies on external discharge paths or natural leakage; designers must account for residual VOUT hold-up time in system power sequencing.
What capacitor types are recommended for MIC5363-2.8YMT input and output?
Micrel specifies X5R or X7R dielectric ceramic capacitors of 1µF (minimum) for both input and output. X7R offers ±15% capacitance stability over temperature and is preferred for highest reliability; X5R is acceptable with slightly wider drift. Y5V and Z5U dielectrics are explicitly discouraged due to >50% capacitance loss over temperature, risking instability. All capacitors must be low-ESR and placed within 2mm of their respective pins.
Can MIC5363-2.8YMT operate without a minimum load current?
Yes, the MIC5363-2.8YMT is designed for no-load stability-it remains in regulation with zero output current. This eliminates the need for bleed resistors or dummy loads, reducing BOM count and standby power loss. Ground current remains at ~38µA typical in no-load condition, supporting ultra-low-power sleep modes in portable devices powered by the MIC5363-2.8YMT.
What is the thermal performance of MIC5363-2.8YMT in its 1.2mm × 1.2mm Thin MLF® package?
The MIC5363-2.8YMT has a junction-to-ambient thermal resistance (θJA) of 173°C/W in the standard 1.2mm × 1.2mm Thin MLF® footprint with ePad soldered to a solid ground plane. At 300mA load and 3.6V input, power dissipation is ~0.24W, allowing a maximum ambient temperature of 83°C before reaching the 125°C junction limit. Performance improves significantly with additional copper area or thermal vias under the ePad.
