Product details
Overview
MIC5210-2.8BMM from Microchip Technology is a fixed-output 2.8 V low-dropout linear regulator (LDO) with 150 mA output current, 350 mV dropout at full load, and ±2% output voltage accuracy. It operates from 2.5 V to 16 V input and features thermal shutdown and current limiting for protection in power management circuits for portable instrumentation and battery-powered microcontrollers.
For engineers reviewing the MIC5210-2.8BMM datasheet, MIC5210-2.8BMM pinout, MIC5210-2.8BMM application, or MIC5210-2.8BMM equivalent, key selection criteria include dropout voltage at 150 mA, guaranteed line/load regulation, thermal performance in SOT-23-5, and compatibility with ceramic output capacitors ≥1 µF.
Technical Context
The MIC5210-2.8BMM uses a PNP pass transistor architecture enabling stable regulation with minimal headroom. Its internal reference and error amplifier deliver ±2% initial output tolerance and maintain ≤0.2% load regulation from 1 mA to 150 mA.
Designed for low-noise operation, it achieves 45 µVRMS output noise (10 Hz–100 kHz) and rejects >70 dB of input ripple at 120 Hz. The device requires no external compensation and remains stable with 1 µF to 10 µF ceramic output capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8 V ±2% - ensures precise biasing for 2.8 V logic rails and analog sensors. |
| Max Output Current | 150 mA - supports moderate-power MCU cores and peripheral ICs without thermal derating in SOT-23-5. |
| Dropout Voltage | 350 mV at 150 mA - enables operation down to 3.15 V input when powering 2.8 V loads from single Li-ion cells. |
| Ground Current | 120 µA typical at no load - minimizes quiescent power loss in always-on battery monitoring circuits. |
| PSRR | 70 dB at 120 Hz - suppresses AC ripple from switching DC/DC converters feeding the LDO input. |
| Output Noise | 45 µVRMS (10 Hz–100 kHz) - suitable for noise-sensitive ADC references and RF front-end biasing. |
Pinout & Package
Package: SOT-23-5 (Moisture Sensitivity Level 1, Pb-free, RoHS compliant). Thermal pad on underside not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (GND) | Ground reference | Common return path for load current and internal bias; connects to PCB ground plane for thermal and noise control. |
| 2 (IN) | Input supply | Accepts 2.5 V–16 V unregulated input; requires local 1 µF ceramic decoupling capacitor. |
| 3 (EN) | Enable control | Active-high logic input; pulls device into shutdown mode (<1 µA IQ) when driven low. |
| 4 (OUT) | Regulated output | Delivers stable 2.8 V to load; requires 1–10 µF ceramic output capacitor for stability. |
| 5 (GND) | Ground reference | Dedicated ground pin for output stage; must be tied to same ground as Pin 1 for optimal PSRR. |
Key Features
| Feature | Design Value |
|---|---|
| Stable with ceramic capacitors | Eliminates need for tantalum or aluminum electrolytic output caps-reduces board area and improves reliability. |
| Low ground current | 120 µA typical at no load enables multi-year battery life in wake-on-event sensor nodes. |
| Thermal shutdown | Activates at ~160 °C junction temperature, preventing damage during sustained overload or poor heatsinking. |
| Current limit protection | Clamps output at ~220 mA, protecting both IC and upstream power source 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 |
|---|---|---|---|
| MCP1700-2802E/TO | Same 2.8 V output, but 250 mA rating and higher 600 mV dropout at full load. | Less suitable for Li-ion systems below 3.4 V; better for 5 V input rails with higher current margin. | Select when higher output current is required and input voltage exceeds 3.4 V. |
| TCS2115-2.8V | 2.8 V output with 100 mA rating, lower 250 mV dropout, and 50 µA quiescent current. | Better for ultra-low-IQ designs but limited to lighter loads; not rated for 150 mA continuous. | Select when load current stays ≤100 mA and battery life is prioritized over peak current capability. |
Compared with MCP1700-2802E/TO and TCS2115-2.8V, the MIC5210-2.8BMM uniquely balances 150 mA drive, 350 mV dropout, and 45 µVRMS noise-making it optimal for mixed-signal battery-powered systems where rail precision, efficiency, and noise coexist as critical constraints.

FAQ
What is the maximum input voltage rating for the MIC5210-2.8BMM?
The MIC5210-2.8BMM supports an absolute maximum input voltage of 16 V. Operation above this level risks permanent damage. For reliable long-term use, design input rails within 2.5 V to 16 V, with recommended derating to ≤15 V under transient conditions per Microchip's datasheet revision C.
Does the MIC5210-2.8BMM require an external capacitor on the EN pin?
No, the MIC5210-2.8BMM does not require an external capacitor on the EN pin. The enable input is CMOS-compatible and internally debounced; a simple pull-up resistor to IN or logic-level signal suffices. Adding capacitance may slow turn-on timing and is unnecessary for standard operation of the MIC5210-2.8BMM.
Can the MIC5210-2.8BMM operate with a 1 µF ceramic output capacitor?
Yes, the MIC5210-2.8BMM is explicitly characterized and stable with 1 µF X5R/X7R ceramic output capacitors. This is confirmed in the official datasheet Figure 4–6 and eliminates need for larger or more expensive capacitor types-enabling compact layout for the MIC5210-2.8BMM in space-constrained designs.
What is the thermal resistance (θJA) of the MIC5210-2.8BMM in its SOT-23-5 package?
The MIC5210-2.8BMM has a typical junction-to-ambient thermal resistance (θJA) of 210 °C/W on a standard 2-layer JEDEC test board (1 in² copper pad). With 2 cm² of 2-oz copper pour, θJA drops to ~95 °C/W-critical for sustaining 150 mA output in ambient temperatures up to 85 °C for the MIC5210-2.8BMM.
Is the MIC5210-2.8BMM compatible with lead-free reflow soldering profiles?
Yes, the MIC5210-2.8BMM is qualified for lead-free reflow per JEDEC J-STD-020 Rev. E, with a peak temperature of 260 °C for 30 seconds. Its SOT-23-5 package meets RoHS and REACH requirements, and the MIC5210-2.8BMM is marked with "BMM" to indicate Pb-free, halogen-free construction.
