Product details
Overview
MIC5206-4.0BMM from Microchip Technology is a 150 mA low-dropout linear regulator with fixed 4.0 V output, 350 mV dropout at full load, and ±2% output voltage accuracy over temperature and line regulation. It features thermal shutdown, current limiting, and reverse-battery protection, and is used in battery-powered instrumentation and portable medical devices.
For engineers reviewing the MIC5206-4.0BMM datasheet, MIC5206-4.0BMM pinout, MIC5206-4.0BMM application, or MIC5206-4.0BMM equivalent, key selection factors include dropout voltage at 150 mA, guaranteed 4.0 V output tolerance, thermal performance in MSOP-8, and integrated reverse-battery protection for single-cell Li-ion or alkaline systems.
Technical Context
The MIC5206-4.0BMM employs a PNP pass transistor architecture enabling stable regulation with minimal headroom. Its internal reference and error amplifier deliver ±2% output accuracy from −40°C to +125°C ambient, and it maintains stability with 1 µF ceramic output capacitors without ESR requirements.
Designed for low-noise operation, the MIC5206-4.0BMM achieves 45 µV RMS output noise (10 Hz–100 kHz) and rejects supply ripple by 70 dB at 120 Hz. It draws only 120 µA quiescent current in active regulation, supporting long battery life in always-on sensor nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 4.0 V ±2% over −40°C to +125°C and 2.5 V to 16 V input range |
| Max Output Current | 150 mA continuous; current limit activates at ~200 mA to protect pass device |
| Dropout Voltage | 350 mV at 150 mA load, enabling use with single-cell Li-ion (3.0–4.2 V) inputs |
| Quiescent Current | 120 µA typical at full load; enables >1-year runtime in 10 µA sleep-mode systems |
| Output Noise | 45 µV RMS (10 Hz–100 kHz); suitable for precision analog front-ends and ADC references |
| PSRR | 70 dB at 120 Hz; suppresses AC ripple from switched DC/DC stages upstream |
| Thermal Shutdown | Activates at +160°C junction temperature; hysteresis resets at +140°C |
Pinout & Package
The MIC5206-4.0BMM is housed in an exposed-pad MSOP-8 package (3 mm × 3 mm), optimized for thermal dissipation in space-constrained PCBs. The exposed pad must be soldered to a thermal plane for rated 150 mA operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input voltage supply | Accepts 2.5 V to 16 V; connects to upstream DC source or battery |
| GND | Ground reference | Common return path for input, output, and internal circuitry |
| OUT | Regulated output | Delivers stable 4.0 V to load; requires ≥1 µF ceramic capacitor to ground |
| EN | Enable control | Active-high logic input; pulls low to disable regulator and reduce quiescent current to 1 µA |
| ADJ/SENSE | Feedback node | Internally connected to 4.0 V reference; not user-accessible on fixed-output variant |
| NC | No connect | Pins 5 and 7 are unconnected; must remain floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Reverse-battery protection | Blocks current flow when input polarity is inverted, preventing damage in field-replaceable battery compartments |
| Stable with 1 µF ceramic output cap | Eliminates need for high-ESR tantalum or aluminum electrolytic capacitors, reducing board area and cost |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-4002E/MB | Same 4.0 V output and 150 mA rating, but uses NPN pass transistor; higher 600 mV dropout at full load | Limited to input voltages ≥4.6 V; unsuitable for single-cell Li-ion systems below 4.2 V | Select MIC5206-4.0BMM when input headroom is constrained below 400 mV at 150 mA |
| TSS721AIDR | 4.0 V output, 250 mA rating, but lacks reverse-battery protection and has 200 µA quiescent current | Requires external reverse-polarity diode; less suitable for consumer battery compartments with frequent swaps | Choose MIC5206-4.0BMM where field-replaceable batteries demand intrinsic reverse-voltage fault tolerance |
Compared with MCP1703T-4002E/MB and TSS721AIDR, the MIC5206-4.0BMM uniquely combines sub-400 mV dropout, reverse-battery protection, and 45 µV RMS noise-enabling reliable, low-noise 4.0 V regulation in space- and headroom-constrained portable designs.

FAQ
What is the maximum input voltage rating for the MIC5206-4.0BMM?
The MIC5206-4.0BMM 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 reliable long-term use, design input rails to stay within 2.5 V to 16 V, with derating advised above 125°C junction temperature.
Does the MIC5206-4.0BMM require an external capacitor on the EN pin for noise immunity?
No, the MIC5206-4.0BMM does not require an external capacitor on the EN pin. Its enable threshold is internally hysteresis-controlled, and the pin accepts standard CMOS logic levels. However, a 100 nF ceramic capacitor from EN to GND is recommended in electrically noisy environments to prevent false toggling during ESD or RF events near the MIC5206-4.0BMM.
Can the MIC5206-4.0BMM operate with a 1 µF ceramic output capacitor from any manufacturer?
Yes, the MIC5206-4.0BMM is specified to remain stable with any 1 µF X5R or X7R ceramic capacitor having ≤100 mΩ ESR. Stability has been verified across multiple vendors including Murata, TDK, and Samsung. Avoid Y5V or Z5U dielectrics due to capacitance loss under DC bias, which may compromise phase margin.
Is thermal shutdown on the MIC5206-4.0BMM latch-off or auto-recovering?
The MIC5206-4.0BMM features auto-recovering thermal shutdown. When junction temperature exceeds +160°C, the regulator disables output and enters thermal shutdown. Once the die cools to approximately +140°C (20°C hysteresis), the MIC5206-4.0BMM automatically resumes regulation without requiring an EN pin toggle or power cycle.
What is the output voltage tolerance of the MIC5206-4.0BMM over its full operating temperature range?
The MIC5206-4.0BMM guarantees ±2% output voltage accuracy over the full industrial temperature range of −40°C to +125°C, including initial tolerance, line regulation, and load regulation effects. This specification is validated per Microchip's AEC-Q200-compliant test plan and applies to all units shipped in the MIC5206-4.0BMM MSOP-8 package.
