Product details
Overview
MIC5206-5.0BM5-TR from Micrel is a 150mA low-noise LDO regulator in SOT-23-5 package, delivering fixed 5.0V output with ±2% accuracy, 165mV dropout at 150mA load, and 600µA ground current at 100mA - designed for battery-powered handheld devices requiring stable, ultra-low-quiescent-power regulation.
For engineers reviewing the MIC5206-5.0BM5-TR datasheet, MIC5206-5.0BM5-TR pinout, MIC5206-5.0BM5-TR application, or MIC5206-5.0BM5-TR equivalent, key selection criteria include guaranteed 150mA output capability, logic-compatible enable/shutdown control, open-collector error flag for undervoltage monitoring, reversed-battery protection, and compatibility with ceramic output capacitors down to 1.0µF (no BYP) or 2.2µF (with BYP).
Technical Context
The MIC5206-5.0BM5-TR implements a CMOS-based LDO architecture with internal voltage reference, precision error amplifier, and PNP pass transistor - enabling ultra-low dropout and tight line/load regulation. Its enable input accepts TTL/CMOS logic levels (VIH ≥ 2.0V, VIL ≤ 0.4V), and its open-collector FLAG pin asserts low when output drops >5% below nominal.
It features built-in thermal shutdown and current limiting, operates across –40°C to +125°C junction temperature, and supports input voltages from +2.5V to +16V. The SOT-23-5 variant lacks the reference bypass (BYP) pin present in MSOP-8 versions, so noise performance relies on external output capacitor selection rather than internal reference filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±2% over full temperature and load range - ensures stable MCU core or peripheral rail without external feedback. |
| Max Output Current | 150mA guaranteed - sufficient for powering microcontrollers, sensors, or RF modules in portable systems. |
| Dropout Voltage | 165mV at 150mA - enables operation from single-cell Li-ion (3.0V min) or dual-cell alkaline (3.2V min) inputs. |
| Ground Current | 600µA at 100mA load - minimizes battery drain in always-on subsystems like real-time clocks or keep-alive memory. |
| Enable Threshold | VIL ≤ 0.4V (shutdown), VIH ≥ 2.0V (enable) - compatible with 3.3V and 5V logic families without level shifting. |
| Error Flag | Open-collector FLAG active low at >5% undervoltage - provides system-level fault detection without additional supervisor IC. |
| Input Voltage Range | +2.5V to +16V - supports wide-input applications including industrial 12V rails and battery-backed supplies. |
Pinout & Package
SOT-23-5 package: 2.9mm × 1.6mm × 1.1mm body, gull-wing leads, JEDEC MO-178AC compliant. Thermal resistance θJA = 220°C/W on FR4 board with no ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Supply Input | Accepts 2.5V–16V unregulated input; requires 1µF decoupling if >10" wire length or battery source. |
| 2 - GND | Ground Reference | Common return for input/output/enable/flag; must be low-impedance connection to minimize noise and dropout. |
| 3 - EN | Enable/Shutdown Input | CMOS/TTL-compatible control: high ≥2.0V enables regulator; low ≤0.4V disables it, reducing quiescent current to <5µA. |
| 4 - FLAG | Undervoltage Error Flag | Open-collector output pulled low when VOUT falls >5% below 5.0V; requires external pull-up (e.g., 47kΩ to IN). |
| 5 - OUT | Regulated Output | Delivers 5.0V ±2% at up to 150mA; requires 1.0µF (no BYP) or 2.2µF (if using external noise-reduction techniques) ceramic capacitor to GND. |
Key Features
| Feature | Design Value |
|---|---|
| Reversed-battery protection | Prevents damage from accidental reverse polarity connection - eliminates need for external series diode and associated voltage drop. |
| "Zero" off-mode current | Quiescent current <5µA in shutdown - extends shelf life and runtime in battery-critical applications like smoke detectors or remote sensors. |
| Thermal & current limiting | Internally limits power dissipation and output current to prevent failure under overload or high ambient conditions. |
| Tight load regulation | ΔVOUT/VOUT < 0.2% from 0.1mA to 150mA - maintains stable voltage across dynamic load profiles without external compensation. |
| Ultra-low-noise design | Output noise optimized via internal architecture and external capacitor selection - achieves <20µVRMS with proper COUT and layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-5002E/TO | 250mA rated, 6µA quiescent current, no FLAG output, SOT-23-3 package (no EN/FLAG pins) | Lacks enable control and fault reporting - suitable only for always-on, non-monitored rails | Select when lowest quiescent current is critical and system-level supervision replaces FLAG functionality. |
| TPS76350DBVR | 150mA rated, 85µA quiescent current, integrated thermal/overcurrent protection, SOT-23-5 package with EN/FLAG | Higher quiescent current but includes power-good flag and tighter initial accuracy (±1%) | Select when higher accuracy and robust fault signaling outweigh ultra-low IQ requirements. |
Compared with MIC5206-5.0BM5-TR, MCP1700-5002E/TO offers lower IQ but sacrifices controllability and monitoring, while TPS76350DBVR trades some efficiency for enhanced accuracy and integrated power-good signaling - making MIC5206-5.0BM5-TR optimal for battery-constrained systems needing both low IQ and system-level fault awareness.

FAQ
What is the minimum input voltage required for MIC5206-5.0BM5-TR to maintain regulation?
The MIC5206-5.0BM5-TR requires a minimum input voltage of 5.165V to sustain 5.0V output at 150mA load, based on its 165mV dropout specification. At lighter loads, dropout drops to 17mV, allowing operation down to ~5.017V. Input must remain ≥2.5V per absolute ratings, but regulation is only guaranteed above VOUT + dropout.
Does MIC5206-5.0BM5-TR require an external bypass capacitor on the BYP pin?
No - the MIC5206-5.0BM5-TR is the SOT-23-5 variant and does not include a BYP pin. That feature is exclusive to the 8-pin MSOP (BMM/YMM) versions. Noise reduction for MIC5206-5.0BM5-TR relies solely on output capacitor selection (1.0µF minimum) and PCB layout.
Can MIC5206-5.0BM5-TR be used without connecting the EN pin?
Yes - if enable functionality is not needed, connect EN (pin 3) directly to IN (pin 1) to permanently enable the MIC5206-5.0BM5-TR. Leaving EN floating is prohibited, as it may cause erratic behavior or unintended shutdown due to noise coupling.
What is the maximum power dissipation capability of MIC5206-5.0BM5-TR at 25°C ambient?
With θJA = 220°C/W on standard FR4, the MIC5206-5.0BM5-TR can safely dissipate up to 450mW at 25°C ambient before reaching its 125°C max junction temperature - corresponding to ~90mA at 5V dropout (VIN = 10V) or 150mA at 3V dropout (VIN = 8V).
Is MIC5206-5.0BM5-TR compatible with ceramic output capacitors?
Yes - the MIC5206-5.0BM5-TR is stable with ceramic output capacitors as low as 1.0µF (no BYP) or 2.2µF (if using noise-reduction techniques). It does not require ESR-based damping, unlike older LDO architectures, simplifying design and reducing BOM count.
