Product details
Overview
MIC5210-2.9BMM from Microchip Technology is a fixed-output 2.9V low-dropout linear regulator (LDO) with 150mA output current, 350mV dropout at full load, and ±2% output voltage accuracy. It operates from 2.5V to 16V input, features thermal shutdown and current limiting, and is used in portable instrumentation and battery-powered microcontroller power rails.
For engineers reviewing the MIC5210-2.9BMM datasheet, MIC5210-2.9BMM pinout, MIC5210-2.9BMM application, or MIC5210-2.9BMM equivalent, key selection criteria include dropout voltage under load, quiescent current in active mode, thermal performance in SOT-23-5, and compatibility with Li-ion and multi-cell alkaline supply rails.
Technical Context
The MIC5210-2.9BMM integrates a PNP pass transistor with internal biasing and error amplifier feedback to maintain regulated 2.9V output across line, load, and temperature variations. Its internal reference is trimmed during final test to ensure ±2% initial accuracy without external components.
It delivers stable regulation with 150mA maximum output while maintaining 350mV dropout at IOUT = 150mA and VIN ≥ 3.25V. Thermal shutdown activates at junction temperatures exceeding 160°C, and foldback current limiting engages above 250mA typical.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 – GND | Ground reference | Common return for regulator feedback and load current |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-2902E/TO | Same 2.9V output, but 250mA rated; higher 1.6µA quiescent current in shutdown, no enable pin | Used in space-constrained designs where lower IQ in shutdown is critical | Select MCP1700-2902E/TO only if shutdown IQ < 1µA is required and enable functionality is unnecessary |
| TPS76329DBVR | 2.9V output, 150mA rating, but 85µA typical quiescent current; requires 2.2µF minimum output capacitance | Preferred in systems needing lowest possible active IQ and tighter load transient response | Choose TPS76329DBVR when optimizing for active-mode battery life and faster load step recovery |
Compared with MIC5210-2.9BMM, MCP1700-2902E/TO offers higher current headroom but lacks enable control, while TPS76329DBVR delivers lower active IQ and better transient response at the cost of larger output capacitor requirement.

FAQ
What is the maximum input voltage rating for MIC5210-2.9BMM?
The MIC5210-2.9BMM supports an absolute maximum input voltage of 16V. Operation above this level risks permanent damage. For automotive applications with potential load dump transients, pairing with a transient voltage suppressor (TVS) diode upstream of the MIC5210-2.9BMM is recommended to clamp input spikes before they reach the regulator's IN pin.
Does MIC5210-2.9BMM require an external capacitor on the ADJ/SENSE pin?
No. The MIC5210-2.9BMM is a fixed-output variant; its ADJ/SENSE pin is internally connected to the output and not accessible for external feedback adjustment. This pin must be left unconnected or tied directly to OUT - no external resistor divider or capacitor is needed or supported for this part number.
Can MIC5210-2.9BMM operate with a 1µF ceramic output capacitor?
Yes. The MIC5210-2.9BMM is specifically characterized and stable with a 1µF X5R or X7R ceramic capacitor on the OUT pin. Unlike many older LDOs, it does not require tantalum or aluminum electrolytic capacitors, enabling smaller PCB area and improved reliability in temperature-cycling environments.
What is the enable logic polarity and threshold voltage for MIC5210-2.9BMM?
The MIC5210-2.9BMM features an active-high enable input (EN pin). The device turns on when EN voltage exceeds 1.2V (typical) and shuts down when EN falls below 0.4V (typical). An internal 1MΩ pull-up resistor biases EN high by default, allowing operation without external pull-up if enable control is not required.
How does thermal shutdown behave on MIC5210-2.9BMM during sustained overload?
When junction temperature exceeds approximately 160°C, MIC5210-2.9BMM disables the pass transistor and forces output to zero volts. After die cooling by ~20°C, the device automatically recovers and resumes regulation without requiring an enable toggle. This hysteresis prevents rapid cycling during marginal thermal conditions and protects both the MIC5210-2.9BMM and downstream circuitry.
