Product details
Overview
MIC5252-3.0BM5TR from Microchip Technology is a 3.0 V fixed-output, 150 mA low-dropout linear regulator in SOT-23-5 package with 250 mV dropout at full load, 60 µA quiescent current, and ±2% output voltage accuracy-used in portable instrumentation and battery-powered microcontroller power rails.
For engineers reviewing the MIC5252-3.0BM5TR datasheet, MIC5252-3.0BM5TR pinout, MIC5252-3.0BM5TR application, or MIC5252-3.0BM5TR equivalent, key selection criteria include dropout voltage under load, thermal shutdown behavior, reverse-battery protection, and stability with 1 µF ceramic output capacitors.
Technical Context
The MIC5252-3.0BM5TR employs a PNP pass transistor architecture enabling ultra-low dropout operation and inherent reverse-voltage protection. It integrates thermal shutdown and current limiting to prevent damage during fault conditions.
Designed for single-supply systems, it operates from 2.5 V to 16 V input and maintains regulation down to 3.0 V output across temperature (−40°C to +125°C) and line/load variations without requiring external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% - ensures stable logic-level supply for 3.3 V–tolerant MCUs and sensors. |
| Max Output Current | 150 mA - sufficient for low-power microcontrollers, RF transceivers, and analog front-ends. |
| Dropout Voltage | 250 mV at 150 mA - enables operation from single Li-ion or two alkaline cells near end-of-life. |
| Quiescent Current | 60 µA - minimizes standby power loss in always-on battery applications. |
| Input Voltage Range | 2.5 V to 16 V - supports wide-input industrial and automotive auxiliary rails. |
| PSRR | 70 dB at 120 Hz - suppresses ripple from switching pre-regulators or noisy DC sources. |
Pinout & Package
SOT-23-5 package with exposed thermal pad (pin 5), footprint-compatible with industry-standard 5-pin SOT-23 layouts and reflow-solderable per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Enable input | Active-high logic control; pulls internal pass transistor gate to disable output when low. |
| 2 (GND) | Ground reference | Power and signal return path; connects to thermal pad for enhanced heat dissipation. |
| 3 (OUT) | Regulated output | Delivers stable 3.0 V to load; requires ≥1 µF ceramic capacitor for stability. |
| 4 (IN) | Unregulated input | Accepts 2.5–16 V; internal overvoltage clamp protects against transient spikes up to 20 V. |
| 5 (GND/EP) | Thermal pad / GND | Electrically tied to pin 2; soldered to PCB copper pour to reduce θJA by ~35°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Reverse-battery protection | Withstands −16 V input without sinking current or damaging internal circuitry. |
| Thermal shutdown | Activates at +165°C junction temperature and auto-recovers after cooldown. |
| Current limit | 180 mA foldback limit prevents thermal runaway during short-circuit events. |
| Stable with 1 µF ceramic | Eliminates need for bulky tantalum or electrolytic output capacitors. |

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 | Same 3.0 V output, but 250 mA rating and 2 µA quiescent current; SOT-23-3 package lacks enable pin. | No enable control; lower IQ suits ultra-long-life applications where EN functionality is unnecessary. | Select MCP1700-3002E/TO only if enable function is omitted and higher output current is required. |
| TPS7A2030PDQNR | 3.0 V output, 300 mA, 6.5 µA IQ, no reverse-battery protection, requires minimum 0.22 µF ceramic capacitor. | Lacks reverse-voltage tolerance; unsuitable for automotive service environments with risk of battery misconnection. | Choose TPS7A2030PDQNR where ultra-low IQ and higher current are prioritized over reverse-battery robustness. |
Compared with MCP1700-3002E/TO and TPS7A2030PDQNR, the MIC5252-3.0BM5TR uniquely combines enable control, reverse-battery protection, and thermal/current limiting in a 5-pin SOT-23-making it optimal for field-serviceable, battery-reversible, and safety-critical embedded systems.

FAQ
What is the maximum input voltage rating for the MIC5252-3.0BM5TR?
The MIC5252-3.0BM5TR supports an absolute maximum input voltage of 20 V, with continuous operation rated from 2.5 V to 16 V. This 16 V upper limit ensures reliable performance under automotive load-dump conditions per ISO 7637-2, while the 20 V transient rating provides margin against short-duration spikes without latch-up or damage.
Does the MIC5252-3.0BM5TR require an external capacitor for stability?
Yes, the MIC5252-3.0BM5TR requires a minimum 1 µF ceramic capacitor on the output pin for stability across all operating conditions. The device is optimized for X5R/X7R dielectrics and does not require ESR tuning-unlike older LDOs-enabling compact, low-BOM-count designs without tantalum or aluminum electrolytic components.
How does the enable pin (EN) function on the MIC5252-3.0BM5TR?
The EN pin on the MIC5252-3.0BM5TR is active-high and internally pulled down. Driving EN ≥2.0 V enables regulation; pulling EN ≤0.4 V disables the output and reduces quiescent current to <1 µA. This allows precise power sequencing and zero-current sleep states in battery-operated systems using the MIC5252-3.0BM5TR.
Is the MIC5252-3.0BM5TR compatible with lead-free reflow processes?
Yes, the MIC5252-3.0BM5TR uses a RoHS-compliant, lead-free SOT-23-5 package qualified for standard Pb-free reflow profiles per JEDEC J-STD-020. Its maximum peak reflow temperature is 260°C, and the thermal pad (pin 5) must be soldered to PCB copper for both mechanical reliability and thermal performance.
What protection features are integrated into the MIC5252-3.0BM5TR?
The MIC5252-3.0BM5TR integrates reverse-battery protection (−16 V tolerant), thermal shutdown (trip at +165°C), and current limiting (180 mA foldback). These protections operate autonomously without external components, ensuring safe operation during input reversal, overload, or ambient temperature excursions-critical for unattended or field-deployed systems using the MIC5252-3.0BM5TR.
