Product details
Overview
MIC5512-3.0YMT-TR from Micrel is a fixed-output 3.0V, 300mA low-dropout linear regulator in a 6-pin 1.6mm × 1.6mm Thin DFN package, featuring ±1% initial output accuracy, 160mV dropout at full load, and auto-discharge functionality activated on disable-designed for space-constrained battery-powered portable electronics including GPS modules and medical wearables.
For engineers reviewing the MIC5512-3.0YMT-TR datasheet, MIC5512-3.0YMT-TR pinout, MIC5512-3.0YMT-TR application, or MIC5512-3.0YMT-TR equivalent, key selection criteria include guaranteed 300mA output current with 38µA quiescent ground current, stability with 1µF ceramic output capacitors, and operation across –40°C to +125°C junction temperature.
Technical Context
The MIC5512-3.0YMT-TR implements a CMOS-based LDO architecture with active-high enable control and internal 25Ω output discharge path. It operates over 2.5V–5.5V input range and maintains regulation down to 160mV VIN–VOUT differential at 300mA load.
Unlike MIC5514 variants, MIC5512-3.0YMT-TR lacks an internal enable pull-down resistor-its EN pin must be actively driven high to enable and must not be left floating. Thermal shutdown and current limiting provide fault protection under overload or short-circuit conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±1% initial accuracy ensures stable supply for 3.0V logic rails without external feedback components. |
| Max Output Current | 300mA guaranteed continuous output supports moderate-power microcontrollers and sensors without thermal derating in typical layouts. |
| Dropout Voltage | 160mV at 300mA enables operation from 3.16V input-critical for single-cell Li-ion (3.0–3.6V) or 3.3V rail post-regulation. |
| Ground Current | 38µA typical quiescent current minimizes battery drain in always-on keep-alive circuits such as RTC or SRAM backup. |
| Enable Logic | Active-high EN pin requires explicit high-level drive; no internal pull-down-prevents unintended startup during processor boot sequences. |
| Capacitor Stability | Stable with ≥1µF ceramic output capacitor (X5R/X7R), eliminating need for large tantalum or electrolytic types and reducing board area. |
| Operating Temp | –40°C to +125°C junction range supports industrial and automotive-adjacent applications including portable diagnostic tools. |
Pinout & Package
Package: 6-pin 1.6mm × 1.6mm Thin DFN (MT) with exposed ePad (connected to GND for optimal thermal performance and EMI suppression).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN | Enable input | Active-high digital control signal; must be driven-not floating-to avoid indeterminate output state. |
| 2, 5 - NC | No-connect | Internally unconnected; PCB pads may be omitted or tied to GND for mechanical reinforcement only. |
| 3 - VIN | Input supply | Accepts 2.5V–5.5V; requires 1µF ceramic bypass capacitor placed adjacent to pin for high-frequency stability. |
| 4 - VOUT | Regulated output | Delivers fixed 3.0V; internally switches 25Ω discharge path to ground when EN = low, clearing output capacitance rapidly. |
| 6 - GND | Power ground | Main return path for load and quiescent current; must be low-impedance connection to system ground plane. |
| ePad | Exposed heatsink pad | Thermal and electrical connection to GND; improves θJA by >30% and reduces thermal resistance to PCB copper. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-discharge circuit | 25Ω internal NFET discharges output capacitors within microseconds upon disable-prevents residual voltage from interfering with downstream power sequencing. |
| No-load stability | Maintains regulation with zero load current-enables use in CMOS RAM keep-alive circuits without minimum load resistors. |
| Low-noise operation | 175µVRMS output noise (10Hz–100kHz) supports noise-sensitive analog sections like ADC references or RF front-end biasing. |
| High PSRR | 65dB ripple rejection at 1kHz allows clean 3.0V supply even when sourced from noisy switching regulators or shared DC/DC outputs. |
| Robust protection | Integrated thermal shutdown and foldback current limiting prevent damage during sustained overload or output 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 |
|---|---|---|---|
| MIC5514-3.0YMT-TR | Includes internal 4MΩ EN pull-down resistor; otherwise identical specs and pinout. | Suitable where EN signal may float during processor reset or boot-eliminates need for external pull-down resistor. | Select MIC5514-3.0YMT-TR if system lacks dedicated EN control or uses open-drain drivers. |
| Torex XC6210B302MR-G | Same 3.0V/300mA output but 250mV dropout at 300mA; 25µA IQ; SOT-25 package (larger footprint). | Better quiescent current but higher dropout limits use in low-VIN scenarios; SOT-25 requires more PCB area than 1.6×1.6mm DFN. | Choose XC6210B302MR-G only when ultra-low IQ outweighs size and dropout constraints. |
Compared with MIC5514-3.0YMT-TR, the MIC5512-3.0YMT-TR requires external EN control but offers identical regulation performance and smaller thermal footprint; versus XC6210B302MR-G, it trades 13µA higher IQ for 90mV lower dropout and 60% smaller package area-favoring compact, high-efficiency battery systems.

FAQ
What is the dropout voltage specification for MIC5512-3.0YMT-TR at full 300mA load?
The MIC5512-3.0YMT-TR has a maximum dropout voltage of 380mV and a typical value of 160mV at 300mA output current. This means it can maintain 3.0V regulation with as little as 3.16V input under typical conditions-critical for extending battery life in single-cell Li-ion applications where input voltage drops below 3.3V during discharge.
Does MIC5512-3.0YMT-TR include an internal pull-down resistor on the EN pin?
No, MIC5512-3.0YMT-TR does not include an internal pull-down resistor on the EN pin. Its EN pin must be actively driven high to enable regulation and must never be left floating-unlike the MIC5514-3.0YMT-TR variant, which integrates a 4MΩ pull-down. Using MIC5512-3.0YMT-TR without proper EN control risks undefined output behavior during power-up or reset.
Can MIC5512-3.0YMT-TR operate stably with no load connected to VOUT?
Yes, MIC5512-3.0YMT-TR remains stable and in regulation with zero load current-a key differentiator from many legacy LDOs. This capability enables direct use in CMOS RAM keep-alive circuits, real-time clock backup supplies, and other ultra-low-power standby functions without requiring minimum load resistors or additional compensation networks.
What output capacitor value and type are required for stable operation of MIC5512-3.0YMT-TR?
MIC5512-3.0YMT-TR requires a minimum 1µF ceramic output capacitor with X5R or X7R dielectric-placed as close as possible to the VOUT and GND pins. Y5V or Z5U dielectrics are not recommended due to severe capacitance loss over temperature. Larger values do not improve stability or transient response significantly, as the design is optimized for 1µF.
Is MIC5512-3.0YMT-TR RoHS-compliant and halogen-free?
Yes, MIC5512-3.0YMT-TR is manufactured in a GREEN RoHS-compliant 1.6mm × 1.6mm Thin DFN package with NiPdAu lead finish and halogen-free mold compound-meeting JEDEC MSL3 handling requirements and supporting lead-free reflow soldering profiles per IPC/JEDEC J-STD-020.
