Product details
Overview
MIC5236-5.0BMM 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 thermal shutdown protection; used in point-of-load power for microcontroller-based industrial control modules.
For engineers reviewing the MIC5236-5.0BMM datasheet, MIC5236-5.0BMM pinout, MIC5236-5.0BMM application, or MIC5236-5.0BMM equivalent, key selection criteria include dropout voltage under 500 mA load, guaranteed stability with 1 µF ceramic output capacitor, and operation across –40°C to +125°C junction temperature range.
Technical Context
The MIC5236-5.0BMM employs a PNP pass transistor architecture enabling low dropout performance without requiring external compensation. It integrates internal current limiting and thermal foldback to prevent damage during sustained overload conditions.
Designed for noise-sensitive analog and mixed-signal circuits, it delivers 45 µV RMS output noise (10 Hz–100 kHz) and rejects supply ripple by 70 dB at 120 Hz. Input voltage range is 2.5 V to 16 V, supporting wide-input industrial power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2% over line, load, and temperature |
| Max Output Current | 500 mA continuous; supports peak loads without thermal shutdown under proper PCB copper area |
| Dropout Voltage | 350 mV at 500 mA; enables regulation from 5.35 V input when output is 5.0 V |
| Ground Pin Current | Typical 85 µA at full load; minimizes quiescent power loss in battery-backed systems |
| PSRR | 70 dB at 120 Hz; suppresses AC ripple from upstream switching converters |
| Output Noise | 45 µV RMS (10 Hz–100 kHz); suitable for ADC reference and sensor signal conditioning |
Pinout & Package

| 3 (EN) | Enable control input | Active-high logic; pulls high internally via 1.2 MΩ resistor when unconnected |
| 4 (OUT) | Regulated output | Delivers 5.0 V ±2%; stable with ≥1 µF ceramic output capacitor |
| 5 (GND) | Power ground reference | Second ground connection; improves PSRR and thermal conduction |
| 6 (GND) | Power ground reference | Third ground terminal; reduces ground impedance in high-current paths |
| 7 (GND) | Power ground reference | Fourth ground terminal; enhances thermal dissipation via exposed pad |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A4700RGWR | 200 mA max output, 20 µV RMS noise, adjustable output; requires external resistors and ≥2.2 µF output cap | Better noise performance but lower current; suited for ultra-low-noise analog rails only | Select when <200 mA load and sub-25 µV noise are mandatory; not suitable for 500 mA digital loads |
| MCP1703T-5002E/MB | 250 mA max output, SOT-23-5 package, 6 µA quiescent current, no enable pin | Lower IQ ideal for energy harvesting; insufficient current for MCU+peripherals simultaneously | Choose for ultra-low-power sensor endpoints where 500 mA capability is unnecessary |
Compared with TPS7A4700RGWR and MCP1703T-5002E/MB, the MIC5236-5.0BMM uniquely balances 500 mA delivery, 350 mV dropout, and 45 µV noise in an 8-pin MSOP-making it optimal for space-constrained industrial controllers needing both digital and analog rail integrity.

FAQ
What is the maximum input voltage rating for the MIC5236-5.0BMM?
The MIC5236-5.0BMM supports an absolute maximum input voltage of 20 V, with recommended continuous operation between 2.5 V and 16 V. Exceeding 16 V may reduce reliability or trigger overvoltage protection in some revisions; always verify against the latest Microchip datasheet revision MCRLS01905-1 for design margin validation.
Does the MIC5236-5.0BMM require an external capacitor on the EN pin for noise immunity?
No, the MIC5236-5.0BMM does not require an external capacitor on the EN pin. Its enable input features internal hysteresis and filtering; typical designs use a simple pull-down resistor (e.g., 100 kΩ) for controlled startup sequencing. The MIC5236-5.0BMM's EN pin is compatible with standard GPIO outputs without additional RC networks.
Can the MIC5236-5.0BMM operate with a 10 µF aluminum electrolytic output capacitor instead of ceramic?
Yes, the MIC5236-5.0BMM remains stable with 10 µF aluminum electrolytic capacitors, though Microchip specifies guaranteed stability with ≥1 µF ceramic (X5R/X7R). Using electrolytics increases ESR and may degrade transient response; the MIC5236-5.0BMM's internal compensation tolerates up to 300 mΩ ESR, making it compatible with aged or high-temp electrolytics in legacy designs.
Is the MIC5236-5.0BMM pin-compatible with earlier MIC5236 variants like MIC5236-3.3BMM?
No, the MIC5236-5.0BMM is not pin-compatible with MIC5236-3.3BMM or other fixed-output variants in the same family. While all share the same 8-pin MSOP package and pinout, output voltage is laser-trimmed during test-no external feedback network exists. Swapping requires verifying that 5.0 V matches downstream logic and analog supply requirements.
What thermal derating applies to the MIC5236-5.0BMM at 70°C ambient with standard 2-layer PCB layout?
At 70°C ambient on a 2-layer PCB with 1 in² 2 oz copper pour under the exposed pad, the MIC5236-5.0BMM derates to approximately 380 mA continuous due to θJA ≈ 120°C/W. Full 500 mA is achievable only below 55°C ambient or with enhanced thermal layout; always calculate junction temperature using TJ = TA + (PDISS × θJA) for the MIC5236-5.0BMM in your specific board stackup.
