Product details
Overview
MIC5366-2.6YMT-TZ from Micrel is a fixed-output 2.6V, 150mA low-dropout linear regulator in a 4-pin 1mm × 1mm Thin MLF package, featuring auto-discharge on disable, ±2% initial output accuracy, 155mV dropout at 150mA, and 29µA quiescent current - optimized for space-constrained portable electronics requiring fast transient response and ultra-low standby power.
For engineers reviewing the MIC5366-2.6YMT-TZ datasheet, MIC5366-2.6YMT-TZ pinout, MIC5366-2.6YMT-TZ application, or MIC5366-2.6YMT-TZ equivalent, this page delivers verified electrical specifications, thermal performance data, enable-controlled shutdown behavior, and validated ceramic capacitor stability requirements for battery-powered system design.
Technical Context
The MIC5366-2.6YMT-TZ implements a CMOS-based LDO architecture with active-high enable control and an integrated NFET auto-discharge circuit activated when EN is low - enabling rapid VOUT discharge to prevent residual voltage hold-up in powered-down subsystems. It operates across 2.5V–5.5V input range and maintains regulation down to –40°C to +125°C junction temperature.
Its high PSRR (70dB @ 1kHz) and low 200µVRMS output noise support noise-sensitive analog and RF circuitry. Stability is guaranteed with ≥1µF X5R/X7R ceramic output capacitors and no minimum load requirement - critical for CMOS RAM keep-alive and intermittent-power applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.6V ±2% initial accuracy ensures stable core or I/O rail for 2.5V–2.7V logic domains without external feedback. |
| Max Output Current | 150mA guaranteed - sufficient to power multiple low-power microcontrollers, sensors, or RF transceivers from a single regulator. |
| Dropout Voltage | 155mV @ 150mA - enables operation from 2.76V input (e.g., single Li-ion cell at end-of-discharge) while maintaining 2.6V output. |
| Quiescent Current | 29µA typical - minimizes battery drain during active operation; drops to ≤1µA in shutdown mode. |
| PSRR | 70dB @ 1kHz - suppresses switching noise from upstream DC/DC converters, improving ADC reference stability and RF receiver sensitivity. |
| Auto-Discharge | 30Ω NFET path activated when EN = low - discharges 1µF output cap in <1ms, eliminating need for external bleed resistors. |
| Thermal Protection | Integrated thermal shutdown and current limiting - prevents damage during overload or poor PCB heatsinking conditions. |
Pinout & Package
Package: 4-pin 1mm × 1mm Thin MLF (RoHS-compliant, NiPdAu lead finish, exposed heatsink pad). Pin 1 marked with ▲ identifier.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT | Regulated output node | Delivers stable 2.6V to load; requires ≥1µF ceramic capacitor to ground for stability. |
| GND | Power ground reference | Low-impedance return path for load and internal circuitry; must connect directly to thermal pad for optimal thermal performance. |
| EN | Active-high enable input | Logic high (≥1.2V) enables regulation; logic low (≤0.2V) disables output and activates auto-discharge; must not float. |
| VIN | Input supply connection | Accepts 2.5V–5.5V input; requires 1µF ceramic capacitor to GND for high-frequency decoupling and stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 1mm² board area - 75% smaller than SC-70-5, enabling dense portable PCB layouts. |
| Zero-off-mode current | ≤1µA shutdown current - extends battery life in always-off states such as sleep-mode IoT endpoints. |
| No-load stability | Remains in regulation with 0mA load - supports CMOS RAM backup and real-time clock circuits without dummy loads. |
| Fast turn-on time | 50–125µs - enables rapid power sequencing in wake-up events for low-power microcontrollers. |
| Robust protection | Thermal shutdown + foldback current limit - sustains safe operation under short-circuit or overtemperature conditions. |
Applications
| Mobile Phone Baseband | Digital Camera Sensor Bias |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC5365-2.6YMT | No auto-discharge circuit; otherwise identical electrical specs and pinout. | Not suitable where rapid VOUT discharge is required after shutdown (e.g., multi-rail sequencing). | Select MIC5365-2.6YMT only if auto-discharge is unnecessary and cost optimization is prioritized. |
| Torex XC6206P262MR-G | 2.6V fixed, 150mA, SOT-23-5 package; 300mV dropout @ 150mA; no enable pin. | Lacks enable control and auto-discharge; requires external ON/OFF switching for power gating. | Choose XC6206P262MR-G only for simple always-on 2.6V rails where board space allows SOT-23-5 and enable functionality is omitted. |
Compared with MIC5365-2.6YMT, the MIC5366-2.6YMT-TZ adds essential auto-discharge for clean power-down sequencing; versus XC6206P262MR-G, it provides superior dropout, enable control, and 1mm² footprint - making it the only option meeting all three requirements: compact size, programmable enable, and rapid discharge.

FAQ
What is the maximum input voltage rating for MIC5366-2.6YMT-TZ?
The MIC5366-2.6YMT-TZ 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. For long-term reliability in 5V systems, ensure VIN remains within specification, especially under transient conditions.
Does MIC5366-2.6YMT-TZ require an external pull-up resistor on the EN pin?
No - the MIC5366-2.6YMT-TZ features a CMOS-compatible enable input with defined logic thresholds (VIH ≥ 1.2V, VIL ≤ 0.2V) and low input current (<1µA). An external pull-up is unnecessary unless system-level noise immunity requires forced high-state default; floating EN is strictly prohibited as it risks indeterminate output behavior.
Can MIC5366-2.6YMT-TZ operate stably with a 0.47µF output capacitor?
No - the MIC5366-2.6YMT-TZ requires ≥1µF ceramic output capacitance (X5R/X7R dielectric) for guaranteed stability per datasheet specifications. Using 0.47µF violates the minimum capacitance requirement and may cause oscillation or poor transient response, particularly under load steps.
What is the thermal resistance (θJA) of the MIC5366-2.6YMT-TZ package?
The MIC5366-2.6YMT-TZ in its 1mm × 1mm Thin MLF package has a junction-to-ambient thermal resistance (θJA) of 240°C/W under standard JEDEC test conditions. Actual θJA depends on PCB copper area, layer count, and thermal via usage - doubling copper area beneath the exposed pad can reduce θJA by ~20–30°C/W.
Is MIC5366-2.6YMT-TZ RoHS-compliant and halogen-free?
Yes - the MIC5366-2.6YMT-TZ uses a RoHS-compliant, lead-free (Pb-free) 1mm × 1mm Thin MLF package with NiPdAu lead finish and halogen-free mold compound, meeting IPC/JEDEC J-STD-609A Class 1 requirements for green packaging.
