Product details
Overview
MIC5206-3.6BM5-TR from Micrel is a 150mA low-noise LDO voltage regulator with 3.6V fixed output, 165mV dropout at 150mA load, ±2% output voltage accuracy over temperature, and logic-compatible enable/shutdown control - designed for battery-powered handheld devices requiring stable low-power regulation.
For engineers reviewing the MIC5206-3.6BM5-TR datasheet, MIC5206-3.6BM5-TR pinout, MIC5206-3.6BM5-TR application, or MIC5206-3.6BM5-TR equivalent, key selection criteria include dropout voltage under full load, ground current at 100mA, undervoltage flag behavior, SOT-23-5 thermal resistance, and compatibility with ceramic output capacitors.
Technical Context
The MIC5206-3.6BM5-TR implements a CMOS-based LDO architecture with internal bandgap reference, error amplifier, and P-channel pass transistor - enabling ultra-low dropout and minimal quiescent current. Its enable input accepts TTL/CMOS logic levels (VIH ≥ 2.0V, VIL ≤ 0.4V) and drives near-zero shutdown current (≤5µA).
An open-collector error flag (FLAG) asserts low when output drops >5% below nominal, with 3% hysteresis; the SOT-23-5 variant lacks BYP pin, so noise performance relies on external output capacitor selection rather than reference bypassing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.6V ±2% over –40°C to +125°C - ensures stable rail for 3.3V/3.6V logic interfaces without external feedback. |
| Max Output Current | 150mA - supports moderate-power microcontrollers, RF front-ends, or sensor signal chains in portable systems. |
| Dropout Voltage | 165mV at 150mA - enables operation from single-cell Li-ion (3.0V min) or two-cell alkaline (3.2V min) with margin. |
| Ground Current | 600µA at 100mA - minimizes battery drain during active operation; drops to ≤5µA in shutdown mode. |
| Line Regulation | 0.03%/V - maintains tight output stability across input variations from 2.5V to 16V supply range. |
| PSRR | 75dB at 1kHz - suppresses switching noise from upstream DC/DC converters in hybrid power architectures. |
| Thermal Resistance | 220°C/W (θJA, FR4, no ground plane) - defines maximum power dissipation limit before thermal shutdown at ambient temperatures. |
Pinout & Package
SOT-23-5 package: compact 2.9mm × 1.6mm surface-mount footprint with exposed pad option not specified; optimized for space-constrained portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Supply Input | Accepts 2.5V–16V input; requires 1µF decoupling if >10" wire length or battery source. |
| 2 - GND | Ground Reference | Common return for input/output/enable/flag; must connect to low-impedance ground plane for thermal and noise control. |
| 3 - EN | Enable/Shutdown Input | CMOS/TTL-compatible; high ≥2.0V enables regulation, low ≤0.4V disables output and reduces IQ to ≤5µA. |
| 4 - FLAG | Error Flag Output | Open-collector; pulled low when VOUT falls >5% below 3.6V; requires external pull-up to IN or system rail. |
| 5 - OUT | Regulated Output | Delivers 3.6V ±2% at up to 150mA; requires ≥1.0µF output capacitor (tantalum/aluminum, ESR ≤5Ω) for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Undervoltage Monitor with Flag | Active-low FLAG output triggers at –5% VOUT deviation with 3% hysteresis - enables system-level brownout detection without external comparators. |
| Reversed-Battery Protection | Withstands –20V reverse input without damage - eliminates need for external series diode in battery-reversal-prone applications. |
| Current & Thermal Limiting | Internal foldback current limit (~320mA typ) and thermal shutdown at ~150°C - prevents catastrophic failure during overload or poor heatsinking. |
| Logic-Controlled Enable | EN pin draws <25µA in active state and <5µA in shutdown - allows direct interfacing with MCU GPIOs without level-shifting or current-limiting resistors. |
| Zero Off-Mode Current | Quiescent current ≤5µA when disabled - extends shelf life and standby time in always-on battery systems like IoT sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3602E/MB | 250mA rated, 600mV dropout at full load, 1.6µA quiescent current in shutdown - higher current but worse dropout and no FLAG output. | Lacks undervoltage flag and reversed-battery protection; suited for cost-sensitive, non-fault-tolerant consumer applications. | Select when higher output current is required and fault monitoring is handled externally. |
| TPS76336DBVR | 150mA rated, 250mV dropout at 150mA, 85dB PSRR at 1kHz, integrated thermal shutdown - no FLAG pin, no reversed-battery protection. | Superior PSRR and tighter initial accuracy (±1%), but no system-level fault indication or reverse-polarity robustness. | Select when maximum noise rejection is critical and board-level protection is already implemented. |
Compared with MCP1700T-3602E/MB and TPS76336DBVR, the MIC5206-3.6BM5-TR uniquely combines undervoltage flag reporting, reversed-battery tolerance, and sub-200mV dropout in a 5-pin SOT-23 - making it optimal for fault-aware, battery-reversal-prone portable designs where space and reliability are co-prioritized.

FAQ
What is the maximum input voltage rating for the MIC5206-3.6BM5-TR?
The MIC5206-3.6BM5-TR has an absolute maximum input voltage of +20V, but its recommended operating range is +2.5V to +16V. Exceeding 16V during normal operation risks exceeding thermal limits or violating safe operating area constraints, especially at high load currents. Always observe derating curves in the datasheet for sustained operation above 12V.
Does the MIC5206-3.6BM5-TR require an external bypass capacitor on the BYP pin?
No - the MIC5206-3.6BM5-TR uses the SOT-23-5 package and does not include a BYP pin. The BYP function is only available on the 8-pin MSOP variants (e.g., MIC5206-3.6BMM). Noise reduction for the MIC5206-3.6BM5-TR relies solely on proper selection of output capacitance (≥1.0µF) and layout practices, not reference bypassing.
How does the FLAG pin behave during enable/disable transitions on the MIC5206-3.6BM5-TR?
The FLAG pin on the MIC5206-3.6BM5-TR is an open-collector output that goes low when VOUT drops >5% below 3.6V, with 3% hysteresis. During enable, FLAG remains high until regulation is established; during disable, FLAG floats high (requires external pull-up). To avoid indeterminate states, the EN pin fall time must be faster than 100µs during shutdown.
Can the MIC5206-3.6BM5-TR operate stably with ceramic output capacitors?
Yes - the MIC5206-3.6BM5-TR is stable with ceramic output capacitors provided they meet minimum capacitance (1.0µF) and ESR requirements (≤5Ω). Unlike older LDOs, it does not require high-ESR tantalum or aluminum electrolytics. However, ceramic caps must be rated for the full output voltage and placed close to the OUT and GND pins to minimize loop inductance.
What is the thermal shutdown threshold and recovery behavior of the MIC5206-3.6BM5-TR?
The MIC5206-3.6BM5-TR activates thermal shutdown at approximately 150°C junction temperature and remains latched off until die temperature falls by ~20°C (hysteresis). Once cooled, it automatically resumes regulation without external reset. This protects against sustained overload or inadequate PCB copper area, especially critical in the SOT-23-5 package with θJA = 220°C/W on standard FR4.
