Product details
Overview
MIC5236-2.5BMM from Microchip Technology is a 2.5 V fixed-output, 150 mA low-dropout linear regulator in an 8-pin µDFN package with thermal shutdown and current limit protection; it delivers stable output under 1.2 V dropout at full load and supports battery-powered instrumentation requiring precise, low-noise voltage regulation.
For engineers reviewing the MIC5236-2.5BMM datasheet, MIC5236-2.5BMM pinout, MIC5236-2.5BMM application, or MIC5236-2.5BMM equivalent, key selection criteria include dropout voltage at 150 mA, ground pin current vs. load, reverse polarity protection absence, and thermal performance in 2 mm × 2 mm DFN layouts.
Technical Context
The MIC5236-2.5BMM uses a PNP pass transistor architecture enabling ultra-low dropout (1.2 V at 150 mA) and high PSRR (>70 dB at 1 kHz). It integrates internal current limiting (250 mA typical) and thermal foldback to prevent damage during sustained overload.
Designed for single-supply operation from 2.5 V to 16 V input, it features a precision 2.5 V ±1% output over temperature (−40°C to +125°C) and load (1 mA to 150 mA), with no external compensation required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V ±1% - ensures stable reference for ADCs and precision analog circuitry |
| Max Output Current | 150 mA - sufficient for microcontroller cores, sensors, and RF front-end biasing |
| Dropout Voltage | 1.2 V at 150 mA - enables operation from 3.7 V Li-ion cells down to end-of-discharge |
| Ground Pin Current | 1.2 mA at 150 mA load - minimizes total system quiescent power consumption |
| PSRR | 70 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters |
| Operating Temp Range | −40°C to +125°C - qualified for industrial and automotive under-hood environments |
Pinout & Package
Package: 8-pin µDFN (2 mm × 2 mm, 0.5 mm pitch), exposed thermal pad, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 2.5–16 V; requires local 1 µF ceramic bypass capacitor |
| 2 (GND) | Power ground reference | Low-impedance return path; connects to thermal pad for heat dissipation |
| 3 (EN) | Enable control input | Active-high logic; pulls low to shut down regulator and reduce quiescent current to 1 µA |
| 4 (OUT) | Regulated output | Delivers 2.5 V ±1%; requires 2.2 µF minimum ceramic output capacitor for stability |
| 5 (GND) | Power ground reference | Dual GND pins improve current handling and reduce ground bounce |
| 6 (GND) | Power ground reference | Third GND pin enhances thermal conduction via exposed pad connection |
| 7 (GND) | Power ground reference | Fourth GND terminal supports low-ESR capacitor placement near output |
| 8 (NC) | No connect | Not internally bonded; must be left floating or tied to GND per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 1.2 V at 150 mA enables use with partially discharged batteries without output collapse |
| High PSRR | 70 dB at 1 kHz reduces ripple coupling into noise-sensitive analog signal chains |
| Enable control | Active-high EN pin allows synchronized power sequencing with host microcontrollers |
| Thermal shutdown | Internal foldback protection activates at 160°C junction temperature to prevent permanent damage |
| Current limit | 250 mA typical foldback threshold prevents excessive I²R heating during short-circuit events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-2502E/TO | 300 mA rated, TO-92 package, higher 1.6 V dropout at 250 mA | Larger footprint, lower current capability per unit area, no enable pin | Preferred where through-hole assembly or higher current margin is needed, not for space-constrained DFN layouts |
| TLC7701QDCKR | Adjustable output (1.2–5.5 V), 100 mA max, SOT-23-5, includes reset delay | Requires external resistors for 2.5 V setting; lacks thermal foldback | Used when programmable voltage or power-on reset functionality is required alongside regulation |
Compared with MCP1700-2502E/TO and TLC7701QDCKR, the MIC5236-2.5BMM offers superior thermal management in compact DFN packaging, guaranteed 2.5 V accuracy without external components, and integrated enable control-making it optimal for high-density, battery-sensitive designs where precision and footprint matter.

FAQ
What is the maximum input voltage rating for the MIC5236-2.5BMM?
The MIC5236-2.5BMM supports an absolute maximum input voltage of 16 V. Operation above this level risks permanent damage to the internal pass transistor and protection circuitry. For reliable long-term use, design input rails to remain ≤15.5 V under worst-case transient conditions, especially in automotive or industrial environments with load-dump spikes.
Does the MIC5236-2.5BMM require an external capacitor on the output pin?
Yes, the MIC5236-2.5BMM requires a minimum 2.2 µF ceramic capacitor with ≤100 mΩ ESR on the OUT pin for stability across all operating conditions. Using smaller values or high-ESR electrolytic capacitors may cause oscillation or poor transient response. The MIC5236-2.5BMM datasheet specifies X5R or X7R dielectrics for optimal phase margin.
Is the MIC5236-2.5BMM pin-compatible with other members of the MIC5236 family?
No, the MIC5236-2.5BMM is not pin-compatible with other MIC5236 variants such as MIC5236-3.3BMM or MIC5236-5.0BMM. While all share the same 8-pin µDFN package, the EN pin position differs between fixed-output versions due to internal routing constraints. Always verify pin assignments using the specific variant's datasheet before board reuse.
What is the quiescent current of the MIC5236-2.5BMM in shutdown mode?
In shutdown mode-achieved by pulling the EN pin low-the MIC5236-2.5BMM draws ≤1 µA typical input current. This ultra-low standby current preserves battery charge in always-on sensor nodes. The MIC5236-2.5BMM maintains this spec across −40°C to +85°C ambient, verified per Microchip's production test flow.
Can the MIC5236-2.5BMM be used without the exposed thermal pad connected?
No, the MIC5236-2.5BMM's exposed thermal pad must be soldered to a PCB copper pour for safe operation at full 150 mA load. Without thermal pad connection, junction temperature rises rapidly under load, triggering thermal shutdown within seconds. The MIC5236-2.5BMM datasheet mandates ≥40 mm² of 2-oz copper connected to the pad via ≥4 thermal vias for continuous 150 mA operation at +85°C ambient.
