Product details
Overview
MIC5219-2.5BMMTR 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 limiting. It features 350 mV dropout at 150 mA, 60 µA quiescent current, and ±2% output voltage accuracy over temperature and load. It is used in portable instrumentation and battery-powered microcontroller subsystems.
For engineers reviewing the MIC5219-2.5BMMTR datasheet, MIC5219-2.5BMMTR pinout, MIC5219-2.5BMMTR application, or MIC5219-2.5BMMTR equivalent, key selection criteria include dropout voltage at full load, ground pin current variation, line regulation performance, thermal derating behavior, and compatibility with ceramic output capacitors ≥1 µF.
Technical Context
The MIC5219-2.5BMMTR employs a PNP pass transistor architecture enabling stable regulation with minimal headroom. Its internal reference and error amplifier deliver tight DC accuracy and transient response within 50 µs for 100 mA load steps.
Designed for low-noise operation, it achieves 45 µVRMS output noise (10 Hz–100 kHz) and rejects input ripple by 70 dB at 120 Hz. The device requires no external compensation and remains stable with 1 µF to 10 µF ceramic output capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V ±2% over –40°C to +125°C and 1 mA–150 mA load |
| Max Output Current | 150 mA continuous; current limit activates at ~200 mA to protect pass element |
| Dropout Voltage | 350 mV at 150 mA load; enables operation with input as low as 2.85 V |
| Quiescent Current | 60 µA typical at no load; rises to 110 µA at 150 mA, minimizing battery drain |
| PSRR | 70 dB at 120 Hz; suppresses AC ripple from switching supply stages upstream |
| Output Noise | 45 µVRMS (10 Hz–100 kHz); suitable for ADC reference and sensor signal chains |
| Stability | Guaranteed with 1 µF–10 µF X5R/X7R ceramic output capacitor; no ESR requirement |
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 2.85 V to 16 V; connects to bulk capacitor and upstream filter |
| 2 (GND) | Ground reference | Low-impedance return path; ties to thermal pad for optimal heat dissipation |
| 3 (EN) | Enable control input | Active-high logic; pulls high internally via 1 MΩ resistor when unconnected |
| 4 (OUT) | Regulated output | Delivers 2.5 V ±2%; requires local 1 µF ceramic capacitor to GND |
| 5 (GND) | Ground reference | Dual GND pins reduce impedance and improve PSRR; both must connect to PCB ground plane |
| 6 (GND) | Ground reference | See Pin 2 and Pin 5; all three GND pins share same internal node |
| 7 (GND) | Ground reference | Thermal pad connection point; soldered to PCB copper for thermal conduction |
| 8 (NR/ADJ) | Noise reduction / adjust | Connect to GND for fixed 2.5 V mode; open or capacitor to GND reduces output noise further |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 60 µA enables >1-year battery life in always-on sensor nodes using coin cells |
| Low-noise output | 45 µVRMS noise supports 12-bit+ precision analog front-ends without post-regulation filtering |
| Ceramic-capacitor stability | Eliminates need for tantalum or aluminum electrolytic capacitors, reducing board area and cost |
| Thermal shutdown with hysteresis | Shuts down at 160°C and resumes at 140°C, preventing latch-up during sustained overload |
| Current-limit protection | Soft-limits output at ~200 mA to avoid damage 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 |
|---|---|---|---|
| MCP1700T-2502E/MB | 300 mA rated, 17 µA IQ, SOT-23-5 package; higher current but larger dropout (600 mV @ 250 mA) | Better for higher-current digital loads; less suitable for ultra-low-IQ sensor nodes | Select if system needs >150 mA or smaller footprint; verify dropout margin at end-of-battery-life voltage |
| TCS2117-2.5 | 150 mA, 45 µA IQ, 8-pin DFN; lower noise (25 µVRMS) but requires 2.2 µF min ceramic output cap | Preferred for ultra-low-noise analog systems where capacitor size is not constrained | Choose when noise budget is tighter than 45 µVRMS; confirm layout supports dual-GND routing |
Compared with MCP1700T-2502E/MB and TCS2117-2.5, the MIC5219-2.5BMMTR balances ultra-low IQ, moderate output current, and proven ceramic-stability in a thermally enhanced µDFN-making it optimal for space-constrained, battery-sensitive analog-sensing designs.

FAQ
What is the maximum input voltage rating for the MIC5219-2.5BMMTR?
The MIC5219-2.5BMMTR has an absolute maximum input voltage of 16 V. Operation above this level risks permanent damage to the internal pass transistor and protection circuitry. For automotive applications with load-dump transients, external clamping or pre-regulation is recommended to keep VIN within safe limits during fault conditions. Always refer to the Absolute Maximum Ratings table in the official MIC5219 datasheet for derating guidance.
Does the MIC5219-2.5BMMTR require an external capacitor on the NR/ADJ pin?
No, the MIC5219-2.5BMMTR does not require an external capacitor on the NR/ADJ pin for basic operation-it is internally configured for fixed 2.5 V output when this pin is tied to GND. However, connecting a 10 nF capacitor from NR/ADJ to GND further reduces output noise by ~15%, which is beneficial in precision analog applications. Leaving NR/ADJ floating is not recommended.
Can the MIC5219-2.5BMMTR operate with a 1 µF ceramic output capacitor?
Yes, the MIC5219-2.5BMMTR is explicitly characterized and guaranteed stable with a minimum 1 µF X5R or X7R ceramic output capacitor. This eliminates the need for larger, higher-ESR tantalum or aluminum electrolytic capacitors. Ensure the capacitor's voltage rating exceeds the output voltage by at least 50% and that PCB layout minimizes trace inductance between OUT and GND.
How does the enable (EN) pin function on the MIC5219-2.5BMMTR?
The EN pin on the MIC5219-2.5BMMTR is an active-high logic input. When pulled above 1.2 V, the regulator enables and delivers 2.5 V to the OUT pin. When held below 0.4 V, it shuts down, reducing quiescent current to <1 µA. An internal 1 MΩ pull-up resistor ensures default-enable behavior if the pin is left unconnected, simplifying designs where always-on operation is required.
Is the MIC5219-2.5BMMTR compatible with lead-free reflow profiles?
Yes, the MIC5219-2.5BMMTR is RoHS-compliant and qualified for standard lead-free reflow soldering per JEDEC J-STD-020. Its µDFN package supports peak temperatures up to 260°C for 30 seconds. Thermal pad soldering is mandatory for thermal performance and reliability-ensure adequate stencil aperture and solder paste volume to achieve >90% void-free coverage under the exposed pad.
