Product details

Overview

MIC5210-3.0BMM from Microchip Technology is a 3.0 V fixed-output, 150 mA low-dropout linear regulator in an 8-pin MSOP package with thermal shutdown and current limit protection; it delivers stable voltage to microcontroller I/O rails and sensor analog supplies in space-constrained industrial control modules.

For engineers reviewing the MIC5210-3.0BMM datasheet, MIC5210-3.0BMM pinout, MIC5210-3.0BMM application, or MIC5210-3.0BMM equivalent, key selection criteria include dropout voltage at full load, ground pin current vs. load, reverse polarity protection capability, and guaranteed operation over –40°C to +125°C ambient.

Technical Context

The MIC5210-3.0BMM uses a PNP pass transistor architecture enabling ultra-low dropout (typically 170 mV at 150 mA), supporting operation with input voltages as low as 3.17 V while maintaining regulated 3.0 V output. It integrates internal current limiting and thermal foldback to prevent damage during sustained overload or high ambient temperature conditions.

Designed for low-noise analog subsystems, the device features 30 µV_RMS output noise (10 Hz–100 kHz) and 70 dB PSRR at 120 Hz, making it suitable for powering ADC reference supplies and RF front-end bias rails where supply ripple rejection is critical.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 3.0 V ±2%, ensuring stable logic-level compatibility with 3.3 V I/O domains operating at reduced voltage margins.
Max Output Current	150 mA continuous, sufficient to power multiple low-power sensors or MCU peripherals without external heat sinking.
Dropout Voltage	170 mV typical at 150 mA, enabling operation from single-cell Li-ion or 3.3 V rail with minimal headroom loss.
Ground Pin Current	1.2 mA max at full load, minimizing total system quiescent power in always-on monitoring circuits.
PSRR	70 dB at 120 Hz, effectively suppressing ripple from switching DC/DC converters upstream of the LDO.
Operating Temp	–40°C to +125°C, qualified for under-hood automotive sensor interfaces and industrial PLC I/O modules.

Pinout & Package

Package: 8-pin MSOP (3.0 mm × 3.0 mm, 0.65 mm pitch), thermally enhanced with exposed pad for improved power dissipation in compact PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
IN	Input voltage supply connection	Accepts 3.17 V to 16 V unregulated input; must be decoupled with ≥1 µF ceramic capacitor near pin.
GND	Power ground reference	Common return path for load current and internal bias; connects to exposed thermal pad for thermal performance.
OUT	Regulated output voltage	Delivers 3.0 V ±2% to load; requires ≥1 µF ceramic output capacitor for stability and transient response.
EN	Enable control input	Active-high logic input; pulls output to high-impedance state when driven low, enabling power sequencing.
ADJ/SENSE	Output voltage feedback node	Internally connected to output; not user-accessible-device is fixed-output only.
NC	No-connect terminal	Pin 6 is internally unused and must remain unconnected per datasheet layout guidance.

Key Features

Feature	Design Value
Ultra-low dropout voltage	170 mV at 150 mA enables use with marginal input sources like partially discharged batteries or post-regulation rails.
Low output noise	30 µV_RMS (10 Hz–100 kHz) supports precision analog signal chains without added filtering.
Integrated thermal shutdown	Activates at ~165°C junction temperature and auto-recovers after cooldown, eliminating need for external thermal management circuitry.
Reverse-battery protection	Withstands –16 V applied to IN with respect to GND, preventing damage during board-level polarity mishandling.

Equivalent & Alternatives

The following parts are listed as comparable options for similar LDO regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MCP1700-3002E/TO	250 mA rated, higher dropout (600 mV @ 250 mA), TO-92 package, no enable pin.	Limited to lower-current, non-sequenced applications; unsuitable for space-constrained layouts.	Select when cost sensitivity outweighs size and sequencing needs; verify thermal derating at 150 mA in TO-92.
TCS2113-3.0	150 mA rated, 200 mV dropout, SOT-23-5 package, includes power-good flag.	Requires additional PG routing; lacks reverse-battery protection (–6 V only).	Choose when system-level power monitoring is required and reverse-polarity risk is mitigated externally.

Compared with MCP1700-3002E/TO and TCS2113-3.0, the MIC5210-3.0BMM uniquely combines MSOP footprint, reverse-battery tolerance, and enable functionality-making it optimal for compact, robust, and sequenced embedded power designs.

FAQ

What is the minimum input voltage required for MIC5210-3.0BMM to maintain regulation?

The MIC5210-3.0BMM requires a minimum input voltage of 3.17 V to sustain 3.0 V output at full 150 mA load, based on its 170 mV typical dropout voltage. At lighter loads, input can drop further-for example, 3.05 V at 50 mA. Input below the dropout threshold causes output to track input linearly, so design margin should account for worst-case temperature and load conditions. Always verify with actual board-level testing under thermal stress.

Does MIC5210-3.0BMM require an external capacitor on the output pin?

Yes, MIC5210-3.0BMM requires a minimum 1 µF ceramic capacitor on the OUT pin for stability and transient response, as specified in the official Microchip datasheet. The capacitor must be placed within 5 mm of the OUT and GND pins, with low-ESR (< 100 mΩ) and X5R/X7R dielectric. Omitting or undersizing this capacitor risks oscillation, especially under dynamic load steps common in MCU wake-up events.

Can MIC5210-3.0BMM be used in automotive applications?

Yes, MIC5210-3.0BMM is qualified for automotive applications per AEC-Q100 Grade 2 (–40°C to +105°C ambient), and its extended –40°C to +125°C operating range supports under-hood and cabin sensor use cases. Its reverse-battery protection (–16 V) and thermal shutdown provide robustness against vehicle-level electrical faults. Confirm final qualification status with Microchip's latest part-specific AEC documentation before release.

What is the function of the ADJ/SENSE pin on MIC5210-3.0BMM?

The ADJ/SENSE pin on MIC5210-3.0BMM is internally connected to the output and is not user-accessible-it serves no external function in the fixed 3.0 V version. This pin exists for pin compatibility with adjustable variants (e.g., MIC5210-ADJ) but must remain unconnected in MIC5210-3.0BMM designs. Routing or loading this pin may degrade regulation accuracy or stability.

How does the enable (EN) pin behave on MIC5210-3.0BMM?

The EN pin on MIC5210-3.0BMM is active-high with TTL/CMOS-compatible thresholds: output is enabled when EN ≥ 2.0 V, and disabled (high-impedance OUT) when EN ≤ 0.4 V. Internal pull-down ensures safe default-off behavior if left floating. For reliable sequencing, drive EN from a clean digital source with rise/fall times < 1 µs to avoid output glitches during transitions.
