Product details
Overview
MIC5202-3.0BM from Microchip Technology is a 3.0 V fixed-output, low-dropout linear voltage regulator with 150 mA output current capability, 350 mV dropout voltage at full load, and ±2% output voltage accuracy. It operates over an input voltage range of 2.5 V to 16 V and features thermal shutdown and current limiting for robust operation in space-constrained industrial sensor nodes.
For engineers reviewing the MIC5202-3.0BM datasheet, MIC5202-3.0BM pinout, MIC5202-3.0BM application, or MIC5202-3.0BM equivalent, key selection considerations include dropout performance at 150 mA, guaranteed stability with 1 µF ceramic output capacitor, and thermal behavior under continuous load in SOT-23-5 packaging.
Technical Context
The MIC5202-3.0BM employs a PNP pass transistor architecture enabling low dropout operation without requiring external compensation. Its internal reference and error amplifier deliver tight regulation across temperature (−40°C to +125°C) and line/load variations.
It integrates foldback current limiting and thermal shutdown with automatic recovery, eliminating latch-up risk during overload. The device is optimized for use with small ceramic capacitors-no ESR requirements-and supports fast transient response in battery-powered microcontroller supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% - ensures stable I/O supply for 3.3 V logic interfaces with margin for voltage droop |
| Max Output Current | 150 mA - sufficient for ultra-low-power MCUs, sensors, and RF transceivers in portable designs |
| Dropout Voltage | 350 mV @ 150 mA - enables operation down to 3.35 V input, extending battery life in single-cell Li-ion or two-cell alkaline systems |
| Input Voltage Range | 2.5 V to 16 V - supports wide-input industrial power rails and unregulated adapter inputs |
| Ground Pin Current | 1.2 mA @ 150 mA - low quiescent current improves efficiency in always-on monitoring circuits |
| Stability | Stable with ≥1 µF ceramic output capacitor - eliminates need for tantalum or electrolytic capacitors, reducing BOM cost and footprint |
Pinout & Package
Package: SOT-23-5 (Moisture Sensitivity Level 1, Pb-free, RoHS compliant). Compact 2.9 mm × 1.6 mm footprint with 0.95 mm height suitable for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input voltage supply | Accepts 2.5–16 V unregulated input; requires local 1 µF ceramic decoupling |
| GND | Ground reference | Common return path for load current and internal bias; must be low-impedance connection |
| OUT | Regulated output | Delivers 3.0 V ±2% to load; connects directly to 1 µF ceramic output capacitor |
| EN | Enable control | Active-high logic input; pulls output to zero when low, enabling power sequencing and standby mode |
| ADJ/NC | Adjust / No Connect | No connection required; internally tied to reference; not used in fixed-output variant MIC5202-3.0BM |
Key Features
| Feature | Design Value |
|---|---|
| Low Dropout Voltage | 350 mV @ 150 mA enables operation from marginal input sources such as aging batteries or undersized DC-DC outputs |
| Ultra-Low Quiescent Current | 1.2 mA typical ground current at full load reduces standby power loss in always-on IoT endpoints |
| Thermal Shutdown with Auto-Recovery | Prevents permanent damage during sustained overload or poor heatsinking; resumes regulation once junction cools |
| Stable with Ceramic Capacitors | Eliminates ESR dependency and simplifies layout by supporting 1 µF X7R/X5R ceramics on both input and output |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1702-3002E/TO | Same 3.0 V output, but 250 mA rating and 600 mV dropout at full load; SOT-23-3 package (no EN pin) | Lacks enable control and has higher dropout; unsuitable for aggressive battery discharge profiles | Select if enable functionality is unnecessary and higher output current is required |
| TPS70930DBVR | 3.0 V output, 150 mA, 400 mV dropout, but requires minimum 2.2 µF output capacitance and no EN pin | Higher minimum output capacitance increases board area and cost; lacks power sequencing capability | Select only when ceramic capacitor size constraints allow ≥2.2 µF and enable control is not needed |
Compared with MCP1702-3002E/TO and TPS70930DBVR, the MIC5202-3.0BM offers lower dropout, integrated enable, and proven stability with 1 µF ceramic output caps-making it optimal for compact, battery-sensitive, and sequenced-power designs.

FAQ
What is the maximum input voltage rating for the MIC5202-3.0BM?
The MIC5202-3.0BM supports an absolute maximum input voltage of 16 V. Operation above this level may cause permanent damage. For reliable long-term use, design input rails to remain within 2.5 V to 16 V, with derating recommended above 125°C ambient temperature. The MIC5202-3.0BM includes internal protection against overvoltage stress up to its rated limit.
Does the MIC5202-3.0BM require an external capacitor on the ADJ pin?
No, the MIC5202-3.0BM is a fixed-output variant and does not use the ADJ pin. That terminal is internally connected and left unconnected (NC) in this version. External capacitors are required only on IN and OUT pins-1 µF ceramic on each-as specified in the official Microchip datasheet for the MIC5202-3.0BM.
Can the MIC5202-3.0BM operate with a 1 µF ceramic output capacitor?
Yes, the MIC5202-3.0BM is explicitly characterized and guaranteed stable with a minimum 1 µF X5R or X7R ceramic capacitor on the output. This eliminates ESR requirements and allows use of small, low-cost, high-reliability MLCCs-unlike many legacy LDOs that demand higher-value or specific-ESR tantalum capacitors.
What is the thermal shutdown threshold for the MIC5202-3.0BM?
The MIC5202-3.0BM activates thermal shutdown at approximately 160°C junction temperature and automatically recovers once the die cools below ~140°C. This hysteresis prevents cycling near the trip point. The MIC5202-3.0BM's SOT-23-5 package has a θJA of 210°C/W in standard JEDEC 2-layer board conditions.
Is the enable pin (EN) of the MIC5202-3.0BM compatible with 1.8 V logic?
Yes, the EN pin of the MIC5202-3.0BM has a logic-threshold of 0.8 V (min) for low-to-high transition and 0.4 V (max) for high-to-low, making it fully compatible with 1.8 V, 2.5 V, and 3.3 V GPIOs. Pulling EN low disables the output and reduces ground current to 1 µA, supporting ultra-low-power sleep modes in systems using the MIC5202-3.0BM.
