Product details
Overview
MIC5365-2.6YMT-TZ from Micrel is a fixed-output 2.6V, 150mA low-dropout linear regulator in a 4-pin 1mm × 1mm Thin MLF package. It delivers ±2% initial output accuracy, 155mV dropout at full load, and 29µA quiescent current-enabling stable power for ultra-compact portable electronics such as GPS modules and handheld PMPs.
For engineers reviewing the MIC5365-2.6YMT-TZ datasheet, MIC5365-2.6YMT-TZ pinout, MIC5365-2.6YMT-TZ application, or MIC5365-2.6YMT-TZ equivalent, this page provides verified electrical specifications, thermal performance data, enable logic behavior, ceramic capacitor stability requirements, and package-specific layout guidance for production-grade integration.
Technical Context
The MIC5365-2.6YMT-TZ implements a CMOS-based LDO architecture with active-high enable control and internal thermal shutdown. Its feedback loop is optimized for stability with only 1µF ceramic output capacitance, eliminating need for external compensation.
It operates across 2.5V–5.5V input range and maintains regulation down to –40°C, supporting battery-powered systems where input voltage sags under load. The zero-off-mode state draws ≤1µA when EN is low, preserving battery life during standby.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.6V ±2% (initial), ±3% over –40°C to +125°C - ensures consistent core voltage for 2.6V I/O domains. |
| Max Output Current | 150mA guaranteed - sufficient for powering baseband processors or RF front-end ICs in compact devices. |
| Dropout Voltage | 155mV @ 150mA - enables operation from single-cell Li-ion (3.0V min) while maintaining regulation. |
| Quiescent Current | 29µA typical - minimizes standby power loss in always-on subsystems like real-time clocks. |
| PSRR | 70dB @ 1kHz - suppresses switching noise from adjacent DC/DC converters feeding shared input rails. |
| Input Voltage Range | 2.5V to 5.5V - compatible with USB VBUS, Li-ion, and multi-cell alkaline supplies without external regulators. |
| Enable Logic | Active-high, VIH ≥ 1.2V, VIL ≤ 0.2V - interfaces directly with 1.8V/3.3V GPIO without level-shifting. |
Pinout & Package
Package: 4-pin 1mm × 1mm Thin MLF (RoHS-compliant, NiPdAu lead finish, exposed heatsink pad). Footprint occupies only 1mm² PCB area - 75% smaller than SC-70-5.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VOUT) | Regulated output node | Delivers stable 2.6V to load; requires 1µF ceramic capacitor to ground for stability. |
| 2 (GND) | Power and signal reference | Must be connected to low-impedance ground plane; ties to exposed heatsink pad for thermal conduction. |
| 3 (EN) | Enable control input | CMOS-compatible active-high signal; must not float - tie to VIN or MCU GPIO to manage power sequencing. |
| 4 (VIN) | Unregulated input supply | Accepts 2.5V–5.5V; requires 1µF ceramic decoupling capacitor close to pin for high-frequency noise rejection. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 1mm × 1mm Thin MLF package saves >75% board area vs. SC-70-5 - critical for space-constrained wearables and IoT sensors. |
| Low-noise regulation | 200µVRMS output noise (10Hz–100kHz) - preserves signal integrity in analog sensor front-ends and audio codecs. |
| No-load stability | Remains in regulation with zero load - supports CMOS RAM keep-alive circuits without dummy loads. |
| Fault protection | Integrated thermal shutdown and current limiting - prevents damage during short-circuit or overtemperature events. |
| Fast turn-on | 50–125µs output rise time (COUT = 1µF) - meets timing requirements for rapid wake-up sequences in portable devices. |
Applications
| Mobile Phone Baseband Power | Digital Camera Sensor Bias |
|---|---|

IC Role / Device Role / Timing Role: Dedicated low-noise LDO decoupled from noisy system DC/DC; enabled synchronously with playback start. Use Value: 70dB PSRR attenuates 1MHz–10MHz switching harmonics; no-load stability eliminates need for bleed resistors on codec VDD lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC5365-2.6YC5 | Same electrical specs, but in 5-pin SC-70-5 package (larger footprint, 2.1mm × 1.3mm). | Less suitable for ultra-dense layouts; higher θJA (256.5°C/W) limits max ambient temperature at full load. | Select when board space allows larger package and thermal constraints permit. |
| TPS7A0526PDQNR | 2.6V, 200mA, 25µA IQ, 170mV dropout @ 200mA; 1mm × 1mm X2SON package. | Higher current capability and lower IQ, but requires minimum 0.47µF output cap and has different enable polarity (active-low). | Choose for higher load margin or lower standby current; verify enable logic compatibility and layout rework for X2SON footprint. |
Compared with MIC5365-2.6YC5, the MIC5365-2.6YMT-TZ offers 75% smaller PCB area and better thermal resistance; versus TPS7A0526PDQNR, it provides tighter initial accuracy (±2% vs ±3%) and guaranteed stability with 1µF output cap, but lacks active-low enable and higher current headroom.

FAQ
What is the maximum input voltage rating for MIC5365-2.6YMT-TZ?
The absolute maximum input voltage for MIC5365-2.6YMT-TZ is 6V, but the recommended operating range is 2.5V to 5.5V per the datasheet. Exceeding 5.5V may trigger internal protection or cause reliability degradation. For long-term robustness in production designs, maintain VIN ≤ 5.5V and observe derating curves for thermal performance at high ambient temperatures.
Does MIC5365-2.6YMT-TZ require an external discharge circuit?
No, MIC5365-2.6YMT-TZ does not include an auto-discharge function - that feature is exclusive to the MIC5366 variant. When disabled via the EN pin, MIC5365-2.6YMT-TZ enters zero-off-mode (≤1µA), but the output capacitor discharges only through the load. If rapid output discharge is required, an external NMOS switch or resistor network must be added.
Can MIC5365-2.6YMT-TZ operate stably with no load connected?
Yes, MIC5365-2.6YMT-TZ remains stable and in regulation with zero load - a key differentiator from many legacy LDOs. This eliminates the need for minimum load resistors and supports applications like CMOS RAM keep-alive circuits or always-on sensor bias rails where load current drops to zero during sleep modes.
What ceramic capacitor dielectric is recommended for MIC5365-2.6YMT-TZ output?
X7R or X5R dielectric ceramic capacitors are recommended for the MIC5365-2.6YMT-TZ output. These provide stable capacitance over temperature (±15% for X7R) and low ESR, ensuring loop stability. Y5V and Z5U dielectrics are not recommended due to >50% capacitance loss over temperature, which risks instability at extremes.
Is the exposed pad on MIC5365-2.6YMT-TZ electrically connected?
Yes, the exposed heatsink pad (EP) on MIC5365-2.6YMT-TZ is internally connected to GND and must be soldered to a solid ground plane for optimal thermal performance and EMI reduction. Leaving it unconnected degrades θJA by ~30°C/W and increases junction temperature under load, potentially triggering thermal shutdown prematurely.
