Product details
Overview
MIC5350-MMYMT-TR from Micrel is a dual-output ultra-low-dropout linear regulator integrating independent 300mA (VOUT1) and 500mA (VOUT2) LDOs, both fixed at 2.8V, in an 8-pin 2mm × 2mm Thin MLF® package. It delivers 75mV dropout at 300mA and 125mV at 500mA, 30µVRMS output noise, ±2% initial accuracy, and operates from 2.6V–5.5V input - ideal for powering RF sections and camera modules in space-constrained portable devices.
For engineers reviewing the MIC5350-MMYMT-TR datasheet, MIC5350-MMYMT-TR pinout, MIC5350-MMYMT-TR application, or MIC5350-MMYMT-TR equivalent, key selection criteria include dual independent enable control, µCap stability with 2.2µF ceramic outputs, fast 30µs startup, thermal shutdown, and low 130µA quiescent current under full load.
Technical Context
The MIC5350-MMYMT-TR implements two independent CMOS-based ULDO regulators with separate active-high enable inputs (EN1, EN2), allowing asynchronous power sequencing and individual shutdown. Each regulator features internal current limiting, thermal shutdown, and bypass-capacitor-supported noise reduction via dedicated BYP pin.
It achieves stability with only 2.2µF ceramic output capacitors and requires no external compensation. The 90°C/W junction-to-ambient thermal resistance and exposed thermal pad (EPAD) enable reliable 300mA/500mA continuous operation within its 2mm × 2mm footprint at ambient temperatures up to 89°C under typical 3.3V-in/2.8V-out conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.6V to 5.5V - supports single-cell Li-ion, Li-poly, or regulated 3.3V/5V rails without external pre-regulation. |
| Output Voltages | VOUT1 = 2.8V / VOUT2 = 2.8V - fixed dual-rail supply for matched analog/digital core domains in imaging sensors or baseband ICs. |
| Dropout Voltage | 75mV @ 300mA (VOUT1), 125mV @ 500mA (VOUT2) - enables >95% efficiency at light-to-moderate loads with minimal headroom. |
| Output Noise | 30µVRMS (10Hz–100kHz) - meets stringent RF PLL and ADC reference supply requirements without added filtering. |
| Quiescent Current | 130µA with both outputs at max load - minimizes standby power loss in battery-powered always-on subsystems. |
| Start-up Time | 30µs - enables rapid power cycling for camera auto-focus or burst-mode sensor operation. |
| Thermal Shutdown | Active at TJ ≥ 150°C - protects device during transient overloads or poor PCB thermal design. |
Pinout & Package
Package: 8-pin 2mm × 2mm Thin MLF® (TMLF), leadless, RoHS-compliant, NiPdAu finish, halogen-free mold compound, EPAD internally connected to GND for thermal and electrical grounding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Supply Input | Common input rail for both LDOs; requires 2.2µF ceramic bypass to GND for stability. |
| 2 - GND | Ground Reference | Analog/digital ground return; must be low-impedance connection to EPAD and system ground plane. |
| 3 - BYP | Reference Bypass | Connects to 0.1µF capacitor to reduce output noise; optional but recommended for RF-sensitive applications. |
| 4 - EN2 | Enable Input (LDO2) | Active-high logic control for 500mA regulator; must be pulled high or low - never left floating. |
| 5 - EN1 | Enable Input (LDO1) | Active-high logic control for 300mA regulator; enables independent sequencing of dual power domains. |
| 6 - NC | No Connect | Not internally bonded; no electrical function - leave unconnected on PCB. |
| 7 - VOUT2 | LDO2 Output | 500mA regulated 2.8V output; designed for higher-current loads like image sensor analog front-end or RF PA bias. |
| 8 - VOUT1 | LDO1 Output | 300mA regulated 2.8V output; suited for digital core, interface I/O, or low-power logic blocks. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable control | EN1 and EN2 allow precise power sequencing, dynamic load management, and zero-quiescent shutdown of either regulator. |
| µCap-stable with 2.2µF ceramics | Eliminates need for large tantalum or electrolytic capacitors - reduces board area, cost, and failure risk in portable designs. |
| Ultra-low 30µVRMS noise | Enables direct use in noise-critical signal chains (e.g., CMOS image sensor analog supply) without additional LDO stages or ferrite beads. |
| Fast 30µs turn-on time | Supports microsecond-scale power gating in camera auto-focus actuators or burst-mode wireless transceivers. |
| Thermal shutdown + current limit | Provides robust fault protection during short-circuit events or excessive ambient temperature without external circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6216D282MR-G | Single 2.8V LDO (300mA), not dual-output; no independent enable pins; 250mV dropout @ 300mA. | Lacks second output and sequencing capability - requires two separate regulators for dual-rail use. | Select when only one regulated rail is needed and board space allows discrete implementation. |
| Ricoh RP512K282D-TR-F | Dual 2.8V/2.8V LDO (300mA/300mA); same 2mm × 2mm DFN; 120mV dropout @ 300mA; no BYP pin. | Equal output current rating per channel but lower total current capacity; no noise-reduction bypass option. | Choose when matched 300mA channels suffice and ultra-low noise is secondary to cost or footprint. |
Compared with MIC5350-MMYMT-TR, XC6216D282MR-G requires duplication for dual-rail use and offers higher dropout, while RP512K282D-TR-F matches footprint and voltage but sacrifices 200mA output headroom and noise performance - making MIC5350-MMYMT-TR optimal for high-current, low-noise dual-domain systems.

FAQ
What are the output voltage options for the MIC5350-MMYMT-TR?
The MIC5350-MMYMT-TR is factory-configured with fixed 2.8V outputs on both VOUT1 and VOUT2. Other combinations - such as 2.8V/1.8V, 3.0V/1.8V, or 3.3V/2.8V - are available under different part numbers (e.g., MIC5350-2.8/1.8YMT), but MIC5350-MMYMT-TR itself delivers precisely 2.8V on each output rail as specified in its ordering information table.
Does the MIC5350-MMYMT-TR require external compensation components?
No, the MIC5350-MMYMT-TR is internally compensated and stable with only 2.2µF ceramic output capacitors per channel. No external resistors, capacitors, or feedback networks are required - simplifying layout and reducing BOM count. X7R/X5R dielectric types are recommended for optimal temperature stability.
How does the BYP pin function in the MIC5350-MMYMT-TR?
The BYP pin on the MIC5350-MMYMT-TR connects to the internal voltage reference and accepts a 0.1µF ceramic capacitor to ground. This bypass reduces output voltage noise to 30µVRMS and improves PSRR at higher frequencies. Leaving BYP open is acceptable if noise performance is not critical, but the capacitor is strongly advised for RF or imaging applications.
What is the thermal performance of the MIC5350-MMYMT-TR in its 2mm × 2mm package?
The MIC5350-MMYMT-TR has a junction-to-ambient thermal resistance (θJA) of 90°C/W in the standard 2mm × 2mm Thin MLF® package. With 300mA on VOUT1 and 500mA on VOUT2 at 3.3V input and 2.8V output, power dissipation is ~0.4W - allowing a maximum ambient operating temperature of 89°C before thermal shutdown activates.
Can the MIC5350-MMYMT-TR operate without load on either output?
Yes, the MIC5350-MMYMT-TR remains stable with no load on either VOUT1 or VOUT2 - a key advantage over many competing LDOs. This makes it suitable for applications like CMOS RAM keep-alive circuits or standby domains where one output may be idle while the other remains active.
