Product details
Overview
MIC5211-3.0BM6 TR from Microchip Technology is a 3.0 V fixed-output, 150 mA low-dropout (LDO) linear regulator in SOT-23-6 package with 340 mV dropout at 150 mA, ±2% output voltage accuracy, and 60 µA quiescent current-used in portable instrumentation and battery-powered microcontroller power rails.
For engineers reviewing the MIC5211-3.0BM6 TR datasheet, MIC5211-3.0BM6 TR pinout, MIC5211-3.0BM6 TR application, or MIC5211-3.0BM6 TR equivalent, key selection criteria include dropout voltage under load, ground pin current stability, thermal shutdown behavior, and reverse-voltage protection capability.
Technical Context
The MIC5211-3.0BM6 TR employs a PNP pass transistor architecture enabling stable regulation with minimal headroom. It integrates thermal shutdown and current limiting to protect against fault conditions during continuous operation.
Designed for low-noise analog and mixed-signal systems, it delivers 45 µVRMS output noise (10 Hz–100 kHz) and supports input voltages from 2.5 V to 16 V. Its enable pin allows controlled power sequencing in multi-rail designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% - ensures stable logic-level supply for 3.3 V tolerant MCUs without external feedback components. |
| Max Output Current | 150 mA - sufficient to power small microcontrollers, sensors, and RF transceivers in compact portable devices. |
| Dropout Voltage | 340 mV at 150 mA - enables operation down to 3.34 V input, extending usable battery life in single-cell Li-ion or two-cell alkaline systems. |
| Quiescent Current | 60 µA - minimizes standby power loss in always-on monitoring circuits and battery-backed real-time clocks. |
| Output Noise | 45 µVRMS (10 Hz–100 kHz) - preserves signal integrity in ADC reference paths and precision sensor front-ends. |
| PSRR | 70 dB at 120 Hz - suppresses ripple from switching DC/DC converters when used in hybrid power architectures. |
Pinout & Package
SOT-23-6 surface-mount package with exposed thermal pad (pin 6), 1.3 mm × 2.9 mm footprint, rated for 150°C junction temperature and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Enable input | Active-high logic control: drives internal pass transistor when pulled ≥1.4 V; allows system-level power gating. |
| 2 (GND) | Ground reference | Primary return path for load current and bias circuitry; connects to thermal pad for enhanced heat dissipation. |
| 3 (OUT) | Regulated output | Delivers filtered 3.0 V supply; requires ≥1 µF ceramic output capacitor for stability per datasheet layout guidelines. |
| 4 (IN) | Input supply | Accepts 2.5 V–16 V unregulated input; must be decoupled with ≥1 µF ceramic capacitor near pin. |
| 5 (GND) | Ground reference | Dedicated ground pin for feedback network; tied internally to pin 2 but routed separately on PCB for noise isolation. |
| 6 (EPAD) | Thermal pad | Internally connected to GND; soldering improves thermal resistance by up to 40 °C/W versus non-connected pad. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout voltage | 340 mV at full 150 mA load enables use with diminishing battery voltage without brownout. |
| Ultra-low quiescent current | 60 µA supports >1-year battery life in coin-cell-powered IoT endpoints with periodic wake-up cycles. |
| Integrated thermal shutdown | Activates at 150°C junction temperature and auto-recovers after cooldown-no external reset circuit needed. |
| Reverse-voltage protection | Blocks current flow when input is reversed down to –6 V, preventing damage during board assembly or field service. |
| Stable with ceramic capacitors | Guaranteed stability using ≥1 µF X5R/X7R ceramic output caps-eliminates need for larger, less reliable tantalum types. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3002E/TT | 250 mA rating, 175 mV dropout at 250 mA, 2 µA quiescent current-but no enable pin or thermal shutdown. | Lacks EN control and fault protection; suitable only for simple always-on loads with ample input margin. | Select when ultra-low IQ dominates requirements and system-level enable/shutdown is handled externally. |
| TPS7A2030PDBVR | 300 mA rating, 170 mV dropout at 300 mA, 6.5 µA IQ, integrated foldback current limit-but requires minimum 1 µF output cap with 5 mΩ ESR. | Better efficiency at higher loads but more sensitive to capacitor selection; no reverse-voltage blocking. | Prefer for high-current, low-noise applications where input voltage margin exceeds 0.5 V and capacitor sourcing is controlled. |
Compared with MCP1700T-3002E/TT and TPS7A2030PDBVR, the MIC5211-3.0BM6 TR uniquely balances mid-current capability, integrated enable, thermal safety, and reverse-voltage protection in a 6-pin SOT-23-making it optimal for space-constrained, battery-fed systems requiring robustness without external protection circuitry.

FAQ
What is the maximum input voltage rating for the MIC5211-3.0BM6 TR?
The MIC5211-3.0BM6 TR supports an absolute maximum input voltage of 16 V. Operation above this level risks permanent damage to the internal pass transistor and protection circuitry. For automotive environments with load-dump transients, external clamping or pre-regulation is required before the MIC5211-3.0BM6 TR input pin.
Does the MIC5211-3.0BM6 TR require an external capacitor on the output pin?
Yes, the MIC5211-3.0BM6 TR requires a minimum 1 µF ceramic capacitor on the OUT pin for stability. The datasheet specifies X5R or X7R dielectric types with ≤100 mΩ ESR. Omitting this capacitor may cause oscillation or output voltage overshoot during load transients.
How does the enable (EN) pin function on the MIC5211-3.0BM6 TR?
The EN pin on the MIC5211-3.0BM6 TR is active-high with a 1.4 V threshold. When pulled above 1.4 V, the regulator enables output; below 0.8 V, it disables output and reduces quiescent current to 1 µA. This pin supports precise power sequencing in multi-rail systems without external logic.
Is the MIC5211-3.0BM6 TR protected against reverse input voltage?
Yes, the MIC5211-3.0BM6 TR includes reverse-voltage protection that blocks conduction when the IN pin is driven negative relative to GND, down to –6 V. This protects downstream circuitry during incorrect battery insertion or service-level polarity faults without requiring external diodes.
What thermal performance can be expected from the MIC5211-3.0BM6 TR in SOT-23-6 package?
In standard 2-layer FR-4 PCB layout with 1-in² copper pour connected to the EPAD, the MIC5211-3.0BM6 TR achieves θJA ≈ 120°C/W. At 150 mA and 3.34 V input (340 mV dropout), power dissipation is 51 mW-resulting in ~6°C junction rise above ambient, well within its 150°C max rating.
