Product details
Overview
MIC5200-3.3BMM from Microchip Technology is a fixed-output 3.3 V, 100 mA low-dropout (LDO) linear regulator in an 8-pin MSOP package with thermal shutdown and current limit protection; it delivers stable output under 150 mV dropout at full load and supports industrial temperature range operation (-40°C to +125°C) in power management for microcontroller core supplies.
For engineers reviewing the MIC5200-3.3BMM datasheet, MIC5200-3.3BMM pinout, MIC5200-3.3BMM application, or MIC5200-3.3BMM equivalent, key selection criteria include dropout voltage at 100 mA, thermal shutdown behavior, ground pin configuration, and compatibility with ceramic output capacitors in space-constrained embedded designs.
Technical Context
The MIC5200-3.3BMM employs a PNP pass transistor architecture enabling ultra-low dropout performance and high PSRR (>70 dB at 1 kHz). It integrates internal bandgap reference, error amplifier, and protection circuitry without requiring external compensation components.
Designed for low-noise, low-quiescent-current operation, it draws only 120 µA typical quiescent current and maintains regulation down to 2.5 V input while delivering up to 100 mA output current with ±2% initial output voltage accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±2% - ensures precise MCU core rail compliance without external feedback resistors. |
| Max Output Current | 100 mA - sufficient for low-power microcontrollers, sensors, and logic ICs in compact systems. |
| Dropout Voltage | 150 mV at 100 mA - enables operation from 3.45 V input, extending battery life in single-cell Li-ion or 3.6 V supply designs. |
| Quiescent Current | 120 µA typical - minimizes standby power loss in always-on monitoring or IoT edge nodes. |
| PSRR | 70 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Operating Temp | -40°C to +125°C - supports deployment in automotive engine control modules and industrial PLC I/O cards. |
Pinout & Package
Package: 8-pin MSOP (3.0 mm × 3.0 mm, 0.65 mm pitch), thermally enhanced with exposed pad connected to GND for improved heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input Supply | Accepts 2.5 V to 16 V unregulated input; requires local 1 µF ceramic capacitor for stability. |
| 2 (GND) | Ground Reference | Power ground connection; tied internally to exposed thermal pad for thermal and electrical integrity. |
| 3 (EN) | Enable Control | Active-high logic input; pulls output to zero when low, enabling power sequencing in multi-rail systems. |
| 4 (OUT) | Regulated Output | Delivers 3.3 V ±2% to load; requires 1 µF minimum ceramic output capacitor for transient response and stability. |
| 5 (GND) | Ground Reference | Dedicated signal ground pin-separate from Pin 2-to reduce noise coupling in sensitive analog sections. |
| 6 (GND) | Ground Reference | Third ground pin improves current return path distribution and reduces PCB trace inductance. |
| 7 (GND) | Ground Reference | Fourth ground pin enhances thermal conduction and EMI suppression via low-impedance ground plane routing. |
| 8 (GND) | Ground Reference | Exposed thermal pad (Pin 8) must be soldered to PCB copper pour for thermal performance and reliability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-Low Dropout | 150 mV at 100 mA enables use with marginal input voltages where buck regulators are overkill. |
| Ceramic Capacitor Stable | Stable with ≥1 µF X5R/X7R ceramic output caps-reduces board area vs. tantalum or aluminum electrolytic alternatives. |
| Thermal Shutdown | Activates at +160°C junction temperature and auto-recovers after cooldown-prevents permanent damage during overload or poor heatsinking. |
| Current Limit Protection | Internal foldback current limiting prevents excessive power dissipation during short-circuit events on the 3.3 V rail. |
| Low Quiescent Current | 120 µA typical allows >10-year battery life in coin-cell–powered sensor nodes operating in deep-sleep mode. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-3302E/TO | 300 mA output, SOT-23-5 package, 6 µA quiescent current, but 600 mV dropout at full load. | Better for ultra-low IQ battery apps; unsuitable where <200 mV dropout is required at >50 mA. | Select MCP1700-3302E/TO only if quiescent current dominates design priority and load current stays below 50 mA. |
| NCP1117ST33T3G | 1 A output, TO-220/SOT-223, 10 mA quiescent current, 1.2 V dropout at 800 mA. | Higher power, higher thermal mass; not suitable for space-constrained MSOP layouts or low-IQ designs. | Choose NCP1117ST33T3G only when >100 mA continuous load or through-hole assembly is required. |
Compared with MCP1700-3302E/TO and NCP1117ST33T3G, the MIC5200-3.3BMM uniquely balances 100 mA capability, 150 mV dropout, and 120 µA IQ in an 8-pin MSOP-making it optimal for thermally constrained, medium-current embedded systems needing both efficiency and precision.

FAQ
What is the maximum input voltage rating for the MIC5200-3.3BMM?
The MIC5200-3.3BMM supports a maximum input voltage of 16 V, allowing direct use with 12 V automotive or industrial bus rails after basic filtering. This rating is absolute maximum and does not imply recommended operating conditions; sustained operation above 12 V requires careful thermal analysis due to increased power dissipation in the MIC5200-3.3BMM's PNP pass element.
Does the MIC5200-3.3BMM require an external capacitor on the EN pin?
No, the MIC5200-3.3BMM does not require an external capacitor on the EN pin. The enable input is CMOS-compatible with internal pull-down and hysteresis; a simple logic-level signal suffices. Adding capacitance may slow enable/disable transitions and is unnecessary unless intentional soft-start timing is needed-though that function is not specified or guaranteed for the MIC5200-3.3BMM.
Can the MIC5200-3.3BMM operate with a 1 µF ceramic output capacitor?
Yes, the MIC5200-3.3BMM is explicitly designed to be stable with a minimum 1 µF X5R or X7R ceramic output capacitor, as confirmed in Microchip's datasheet revision C. Using smaller or non-ceramic types risks oscillation or degraded transient response, so the MIC5200-3.3BMM must be paired with ≥1 µF ceramic output capacitance for guaranteed stability.
Is the exposed thermal pad on the MIC5200-3.3BMM electrically connected?
Yes, the exposed thermal pad on the MIC5200-3.3BMM is internally connected to GND and must be soldered to a PCB ground plane. Leaving it floating degrades thermal performance and may cause premature thermal shutdown; incorrect pad layout also violates Microchip's recommended footprint for the MIC5200-3.3BMM and voids parametric guarantees.
What is the typical ground pin current for the MIC5200-3.3BMM at full load?
The MIC5200-3.3BMM draws approximately 120 µA quiescent current plus load current through its four dedicated GND pins (Pins 2, 5, 6, 7) and the exposed thermal pad (Pin 8). At 100 mA output, total ground current is ~100.12 mA-distributed across all five ground connections to minimize voltage drop and noise coupling in the MIC5200-3.3BMM's ground network.
