Product details
Overview
MIC5366-2.0YMT-TZ from Micrel is a fixed-output 2.0V, 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 off-state power.
For engineers reviewing the MIC5366-2.0YMT-TZ datasheet, MIC5366-2.0YMT-TZ pinout, MIC5366-2.0YMT-TZ application, or MIC5366-2.0YMT-TZ equivalent, key selection criteria include enable-active-high logic compatibility, 2.5V–5.5V input range, thermal shutdown protection, and stable operation with only 1µF ceramic output capacitance.
Technical Context
The MIC5366-2.0YMT-TZ implements a CMOS-based LDO architecture with internal P-channel pass transistor, enabling low dropout and high PSRR (70dB up to 1kHz). Its auto-discharge function integrates an NFET between VOUT and GND, activated only when EN is low, ensuring rapid output voltage decay without external components.
It operates across –40°C to +125°C junction temperature, supports 1µF X5R/X7R ceramic capacitors on both input and output, and delivers regulated 2.0V output with load regulation of ≤1% from 100µA to 150mA - all while maintaining stability under no-load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.0V ±2% initial accuracy ensures precise biasing for 2.0V-core logic or analog circuitry. |
| Max Output Current | 150mA guaranteed continuous sourcing supports microcontrollers, sensors, and RF ICs in compact handhelds. |
| Dropout Voltage | 155mV @ 150mA enables operation from 2.155V input - critical for single-cell Li-ion or Li-poly battery systems. |
| Quiescent Current | 29µA typical ground current minimizes standby power loss in always-on subsystems. |
| PSRR | 70dB @ 1kHz suppresses switching noise from adjacent DC/DC converters feeding the same rail. |
| Enable Logic | Active-high EN pin with 1.2V VIH threshold ensures direct interfacing with 1.8V/3.3V GPIO without level-shifting. |
| Auto-Discharge | Integrated 30Ω NFET discharges VOUT to GND within microseconds upon disable - eliminates hold-up voltage in power sequencing. |
Pinout & Package
Package: 4-pin 1mm × 1mm Thin MLF (RoHS-compliant, NiPdAu lead finish, exposed heatsink pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (Pin 1) | Regulated output node | Delivers stable 2.0V; requires ≥1µF ceramic capacitor to GND for stability and transient response. |
| GND (Pin 2) | Power and signal reference | Must be connected directly to PCB ground plane; ties to exposed heatsink pad for thermal performance. |
| EN (Pin 3) | Enable control input | CMOS-compatible active-high logic; must not float - tie to VIN or MCU GPIO to prevent indeterminate state. |
| VIN (Pin 4) | Unregulated input supply | Accepts 2.5V–5.5V; requires 1µF ceramic capacitor to GND close to pin for high-frequency decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 1mm² board area - 75% smaller than SC-70, enabling dense portable PCB layouts. |
| Auto-discharge circuit | 30Ω integrated NFET actively pulls VOUT to GND during shutdown, eliminating need for external discharge resistor. |
| No-load stability | Remains in regulation with zero load - essential for memory backup rails and always-on wake-up circuits. |
| Thermal & current protection | Internal thermal shutdown and foldback current limiting prevent damage during overload or ambient overheating. |
| Low-noise operation | 200µVRMS output noise (10Hz–100kHz) preserves signal integrity in ADC reference or RF front-end supplies. |
Applications
| Mobile Phone Baseband | Digital Camera Image Sensor |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC5365-2.0YMT | No auto-discharge circuit; identical pinout, specs, and package. | Lacks controlled VOUT discharge - unsuitable where rapid power-down sequencing is required. | Select MIC5365-2.0YMT only if auto-discharge is unnecessary and cost minimization is prioritized. |
| Torex XC6206P202MR-G | 2.0V fixed, 150mA, SOT-23-5 package; no enable pin; 350mV dropout @ 150mA. | Requires external enable circuitry; higher dropout limits usable input range in low-voltage battery apps. | Choose XC6206P202MR-G only when board space allows SOT-23-5 and enable functionality is implemented externally. |
Compared with MIC5365-2.0YMT and XC6206P202MR-G, the MIC5366-2.0YMT-TZ uniquely combines ultra-small 1mm² footprint, integrated auto-discharge, and 155mV dropout - making it the only option supporting both minimal PCB area and deterministic power-rail collapse in battery-critical portable systems.

FAQ
What is the minimum input voltage required for MIC5366-2.0YMT-TZ to maintain regulation at full 150mA load?
The MIC5366-2.0YMT-TZ requires a minimum input voltage of 2.155V to sustain 2.0V output at 150mA, based on its 155mV dropout specification. Below this, output voltage drops proportionally; operation below 2.5V input is permitted but must account for reduced headroom and potential thermal stress at high ambient temperatures.
Does MIC5366-2.0YMT-TZ require an external pull-up resistor on the EN pin?
No - the MIC5366-2.0YMT-TZ EN pin has CMOS input structure and does not require an external pull-up. However, it must never be left floating; it should be actively driven high by a GPIO or tied to VIN through a series resistor only if open-drain control is needed. Floating EN may cause erratic output behavior.
Can MIC5366-2.0YMT-TZ operate stably with a 0.47µF ceramic output capacitor?
No - the MIC5366-2.0YMT-TZ is specified and characterized for stable operation only with ≥1µF ceramic output capacitance (X5R/X7R dielectric). Using 0.47µF violates the minimum requirement and risks oscillation, especially under dynamic load conditions or elevated temperature.
What is the thermal resistance (θJA) of the MIC5366-2.0YMT-TZ in its 1mm × 1mm Thin MLF package?
The MIC5366-2.0YMT-TZ in the 1mm × 1mm Thin MLF package has a junction-to-ambient thermal resistance (θJA) of 240°C/W under standard JEDEC test conditions. Actual θJA improves significantly with proper PCB copper pour connected to the exposed heatsink pad.
Is the auto-discharge feature of MIC5366-2.0YMT-TZ active during normal operation or only when disabled?
The auto-discharge feature of MIC5366-2.0YMT-TZ is active exclusively when the EN pin is driven low (logic 0), placing the device in shutdown mode. During normal operation (EN high), the discharge NFET is fully off and has no effect on output regulation or load behavior.
