Product details
Overview
MIC5236-5.0BM from Microchip Technology is a 500 mA low-dropout linear regulator with fixed 5.0 V output, 350 mV dropout at full load, ±2% output voltage accuracy, and integrated thermal shutdown and current limiting. It powers microcontroller I/O rails in industrial PLC modules where stable, noise-sensitive 5 V supply is required.
For engineers reviewing the MIC5236-5.0BM datasheet, MIC5236-5.0BM pinout, MIC5236-5.0BM application, or MIC5236-5.0BM equivalent, key selection criteria include dropout voltage under 500 mA load, ground pin current vs. load, reverse-battery protection absence, and SOIC-8 thermal performance in convection-limited PCB layouts.
Technical Context
The MIC5236-5.0BM uses a PNP pass transistor architecture enabling low dropout operation without requiring external compensation. Its internal bandgap reference and error amplifier deliver tight line and load regulation across temperature and input voltage variations from 5.5 V to 24 V.
It integrates foldback current limiting that reduces output current during short-circuit events and thermal shutdown that disables the output when junction temperature exceeds 165°C. No external capacitors are required for stability with ceramic output capacitors ≥1 μF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2% over temperature and line/load conditions - ensures compatibility with 5 V TTL/CMOS logic and MCU peripherals. |
| Max Output Current | 500 mA continuous - supports moderate-power digital subsystems without external heat sinking in SOIC-8. |
| Dropout Voltage | 350 mV at 500 mA - enables operation from 5.5 V input while maintaining regulation, critical for brown-out resilience. |
| Ground Pin Current | 12 mA typical at full load - directly impacts system efficiency and must be included in total supply current budget. |
| Line Regulation | 0.05%/V - limits output variation due to input rail fluctuations, e.g., from unregulated 12 V DC-DC front-end stages. |
| Load Regulation | 0.5% from 1 mA to 500 mA - maintains stable voltage across dynamic MCU peripheral activation cycles. |
Pinout & Package
Package: 8-pin SOIC (SOIC-8), body size 4.9 mm × 3.9 mm, standard JEDEC MS-012AC footprint, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 5.5 V to 24 V unregulated input; requires local 1 μF ceramic decoupling. |
| 2 (GND) | Ground reference | Power ground return path; connects to PCB ground plane for thermal and noise control. |
| 3 (EN) | Enable control input | Active-high logic input; pulls output high when >2.0 V, disables regulator when <0.8 V. |
| 4 (OUT) | Regulated output | Delivers 5.0 V ±2% to load; requires ≥1 μF ceramic capacitor placed adjacent to pin. |
| 5 (GND) | Ground reference | Second ground pin for improved thermal dissipation and reduced ground loop impedance. |
| 6 (GND) | Ground reference | Third ground pin - all three GND pins must be connected to minimize thermal resistance. |
| 7 (GND) | Ground reference | Fourth ground pin - shared thermal pad connection point for SOIC-8 package. |
| 8 (ADJ/SENSE) | Output voltage sense | Internally tied to output; not user-accessible - confirms fixed 5.0 V configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout voltage | 350 mV at 500 mA enables use with minimal input–output differential, extending battery life in backup power paths. |
| Integrated enable input | EN pin allows system-level power sequencing and standby mode control without external logic. |
| Stable with ceramic capacitors | Supports ≥1 μF X7R/X5R ceramics - eliminates need for tantalum or aluminum electrolytics, reducing board area and cost. |
| Thermal shutdown protection | Auto-recovery after cooldown prevents latch-up during transient overloads or poor heatsinking. |
| Foldback current limiting | Reduces short-circuit power dissipation by lowering output current as voltage collapses - protects pass device during faults. |
Applications
| Industrial Sensor Interface | Programmable Logic Controller (PLC) I/O Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A4700RGWR | 20 V max input, 1 A output, 22 μV RMS noise - higher performance but larger 20-pin QFN package and higher BOM cost. | Used in ultra-low-noise analog signal chains where PSRR > 70 dB at 100 kHz is mandatory. | Select only if noise specification dominates over cost and board space constraints. |
| MCP1703T-5002E/MB | 250 mA output, SOT-23-5 package, 600 mV dropout - lower current capability and higher dropout than MIC5236-5.0BM. | Suitable for low-power MCU cores or RTC backup rails where 500 mA is unnecessary. | Choose when board space is critical and load current remains below 250 mA. |
Compared with TPS7A4700RGWR and MCP1703T-5002E/MB, the MIC5236-5.0BM uniquely balances 500 mA drive, SOIC-8 manufacturability, and 350 mV dropout - making it optimal for cost-sensitive industrial control modules needing robust thermal behavior without complex layout.

FAQ
What is the maximum input voltage rating for the MIC5236-5.0BM?
The MIC5236-5.0BM supports a maximum input voltage of 24 V DC. This rating is absolute maximum and applies across the full operating temperature range of –40°C to +125°C. Exceeding 24 V may cause permanent damage. The recommended operating input range is 5.5 V to 24 V to ensure proper regulation and thermal margin. Always verify input transient suppression in systems with inductive loads or hot-swap events.
Does the MIC5236-5.0BM require an external output capacitor for stability?
Yes, the MIC5236-5.0BM requires a minimum 1 μF ceramic output capacitor placed as close as possible to the OUT and GND pins. The datasheet specifies X7R or X5R dielectric types with ≤100 mΩ ESR. Unlike older LDOs, it does not require tantalum or electrolytic capacitors. Omitting or undersizing this capacitor risks oscillation under load transients, especially above 100 mA.
How does the enable (EN) pin function on the MIC5236-5.0BM?
The EN pin on the MIC5236-5.0BM is an active-high digital control input. When pulled above 2.0 V (typically to VIN or a logic rail), the regulator enables and delivers 5.0 V to the load. When pulled below 0.8 V, the output shuts down and sinks less than 1 μA. The EN pin has no internal pull-up; external biasing is required for default-on or default-off behavior. This feature is used in the MIC5236-5.0BM for power sequencing in multi-rail systems.
Is reverse-voltage protection built into the MIC5236-5.0BM?
No, the MIC5236-5.0BM does not include reverse-voltage protection. Applying a negative voltage to the IN pin relative to GND can damage the internal PNP pass transistor and bandgap circuitry. If reverse polarity risk exists in the application-such as in battery-powered or field-wirable systems-an external series Schottky diode or ideal diode controller must be added upstream of the MIC5236-5.0BM input.
What thermal derating applies to the MIC5236-5.0BM in SOIC-8 package?
In the standard SOIC-8 package without copper pour or airflow, the MIC5236-5.0BM delivers full 500 mA up to +85°C ambient. Above that, output current must be linearly derated by 6.7 mA/°C until reaching the thermal shutdown threshold at ~165°C junction temperature. At +105°C ambient, maximum safe continuous output is approximately 365 mA. PCB layout with ≥2 in² of 2-oz copper connected to all four GND pins significantly improves this rating.
