Product details
Overview
MIC5206-2.7BM5-TR from Micrel is a 150mA fixed-output low-dropout linear regulator delivering 2.7V with ±2% output voltage accuracy, 165mV dropout at full load, and 600µA ground current at 100mA - designed for battery-powered handheld systems requiring ultra-low-noise, logic-controlled enable, and undervoltage fault monitoring.
For engineers reviewing the MIC5206-2.7BM5-TR datasheet, MIC5206-2.7BM5-TR pinout, MIC5206-2.7BM5-TR application, or MIC5206-2.7BM5-TR equivalent, this page provides verified package mapping (SOT-23-5), confirmed EN/FLAG functionality, noise-reduction design guidance via BYP pin, and real-world selection alternatives for portable power rail regulation.
Technical Context
The MIC5206-2.7BM5-TR integrates a precision bandgap reference, CMOS-compatible enable input (VIH = 2.0V, VIL = 0.4V), and open-collector error flag output that asserts low when output drops >5% below nominal. Its internal architecture minimizes quiescent current in shutdown (<1µA) and maintains regulation down to 2.5V input.
It features reversed-battery protection, thermal shutdown, and current limiting (320–500mA). The SOT-23-5 variant lacks the BYP pin - unlike MSOP-8 versions - so ultra-low-noise operation (260nV/√Hz) is not supported; PSRR remains ≥75dB at 1kHz with 1µF output capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.7V ±2% over –40°C to +125°C - ensures stable core/logic rail for low-voltage microcontrollers and RF ICs. |
| Max Output Current | 150mA guaranteed - supports single-rail powering of Bluetooth modules, sensors, or small FPGAs without derating. |
| Dropout Voltage | 165mV at 150mA - enables operation from single-cell Li-ion (3.0V min) or two alkaline cells (3.2V min) with margin. |
| Ground Current | 600µA at 100mA load - extends battery life in always-on sensor nodes and wearable devices. |
| Enable Threshold | VIL ≤ 0.4V (shutdown), VIH ≥ 2.0V (enable) - compatible with 3.3V and 5V GPIO without level-shifting. |
| Error Flag | Open-collector FLAG pin active low at >5% undervoltage - enables system-level brown-out detection with external pull-up. |
| PSRR | ≥75dB at 1kHz - suppresses switching noise from upstream DC-DC converters in mixed-signal applications. |
| Thermal Shutdown | Activates at TJ ≥ +125°C - protects against sustained overload or poor PCB thermal layout. |
Pinout & Package
Package: SOT-23-5 (lead-free, RoHS-compliant), 2.9mm × 1.6mm footprint, 1.1mm height - optimized for space-constrained portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Supply Input | Accepts 2.5V–16V input; requires 1µF ceramic capacitor to GND 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 coupling. |
| 3 - EN | Enable/Shutdown Input | CMOS/TTL-compatible control; tie to IN for always-on operation; fast fall time (<100µs) required to avoid FLAG glitch during shutdown. |
| 4 - FLAG | Error Flag Output | Open-collector output; requires external pull-up (e.g., 47kΩ to IN); asserts low on >5% output undervoltage. |
| 5 - OUT | Regulated Output | Delivers 2.7V ±2%; requires ≥1.0µF output capacitor (ceramic/tantalum, ESR ≤5Ω) for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-Controlled Enable | EN pin allows microcontroller-driven power sequencing - reduces system standby current to <1µA when disabled. |
| Undervoltage Monitoring | Integrated comparator with 3% hysteresis drives FLAG pin - eliminates need for external supervisor IC in compact designs. |
| Reversed-Battery Protection | Internal circuitry blocks reverse current flow - prevents damage during incorrect battery insertion in consumer devices. |
| Thermal & Current Limiting | Self-protecting under short-circuit or high ambient conditions - avoids catastrophic failure without external foldback circuitry. |
| High Accuracy & Stability | ±2% initial tolerance, 40ppm/°C tempco, and <0.05%/W thermal regulation - maintains tight voltage rails across temperature and load. |
Applications
| Cellular Handsets | Laptop Subsystem Rails |
|---|---|

IC Role / Device Role / Timing Role: Standalone LDO providing isolated, enable-controlled power domain independent of main CPU rail sequencing. Use Value: Guarantees deterministic power-up timing and brown-out detection via FLAG pin - critical for firmware integrity during hot-plug events. |
| Wearable Health Sensors | Industrial IoT Edge Nodes |
Use Scenario: Supplying ultra-low-power optical heart-rate monitor (PPG) and ADC front-end in fitness trackers. IC Role / Device Role / Timing Role: Primary 2.7V rail generator with zero-off current and precise voltage accuracy for analog signal chain calibration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-2702E/TO | 150mA, 2.7V fixed, 6µA quiescent current, no FLAG or EN pin - only shutdown via VIN removal. | Lacks enable control and fault reporting; suited for simple always-on rails where supervision is handled elsewhere. | Select when board space is tighter (SOT-23-3) and system-level enable/flag logic already exists. |
| Torex XC6206P272MR-G | 150mA, 2.7V fixed, 1.0µA IQ, no FLAG, EN pin with 0.7V threshold - incompatible with 3.3V GPIO without resistor divider. | No undervoltage monitoring; lower IQ benefits multi-year battery life but removes fault visibility. | Prefer for ultra-low-power remote sensors where FLAG is unnecessary and EN compatibility with 1.8V logic is required. |
Compared with MIC5206-2.7BM5-TR, MCP1700-2702E/TO saves board area but sacrifices system-level controllability, while XC6206P272MR-G achieves nanoscale quiescent current at the cost of diagnostic capability and interface flexibility - making MIC5206-2.7BM5-TR optimal for designs needing integrated enable, flag, and robust load transient response.

FAQ
What is the maximum input voltage rating for the MIC5206-2.7BM5-TR?
The MIC5206-2.7BM5-TR has an absolute maximum input voltage of +20V, but its recommended operating input range is +2.5V to +16V. Exceeding +16V risks violating safe operating area limits under load, especially at elevated temperatures. For 2.7V output, typical use cases operate between 3.0V (single Li-ion) and 5.5V (USB-powered systems).
Does the MIC5206-2.7BM5-TR support ultra-low-noise operation with a bypass capacitor?
No - the MIC5206-2.7BM5-TR uses the SOT-23-5 package, which omits the BYP (bypass) pin found only in the 8-pin MSOP variants (e.g., MIC5206-2.7BMM). Therefore, it cannot achieve the 260nV/√Hz noise performance enabled by a 470pF capacitor on the reference node. Its baseline noise remains suitable for most digital and mixed-signal loads.
How does the FLAG pin behave during enable/disable transitions?
The FLAG pin on the MIC5206-2.7BM5-TR is an open-collector output that goes high-impedance when inactive and pulls low only during undervoltage faults (>5% drop). To prevent glitches during power-down, the EN pin's falling edge must be faster than 100µs - achieved using a pull-down resistor or active driver, not RC delays.
Can the MIC5206-2.7BM5-TR be used without an output capacitor?
No - an output capacitor is mandatory for stability. The MIC5206-2.7BM5-TR requires ≥1.0µF ceramic or tantalum capacitor (ESR ≤5Ω) between OUT and GND. Omitting it causes oscillation and potential damage. At loads <10mA, capacitance may be reduced to 0.47µF, but never omitted entirely.
Is the MIC5206-2.7BM5-TR pin-compatible with the LP2980 series?
The MIC5206-2.7BM5-TR uses the same SOT-23-5 pinout as the LP2980 family (IN, GND, EN, FLAG, OUT), enabling direct PCB replacement in many layouts. However, electrical differences exist - including higher PSRR, lower dropout, and tighter accuracy - so validation of transient response and thermal behavior is required before drop-in substitution.
