Product details
Overview
MIC5335-SGYMT-TR from Microchip Technology is a dual-channel, 300 mA ultra-low dropout (ULDO) linear regulator in a 1.6 mm × 1.6 mm Thin DFN-6 package, delivering fixed 3.3 V and 1.8 V outputs with 75 mV dropout at 300 mA, 65 dB PSRR at 1 kHz, and µCap stability using only 1 µF ceramic output capacitors - deployed in space-constrained portable media players and GPS receivers.
For engineers reviewing the MIC5335-SGYMT-TR datasheet, MIC5335-SGYMT-TR pinout, MIC5335-SGYMT-TR application, or MIC5335-SGYMT-TR equivalent, this page delivers verified electrical specs, thermal performance data, dual enable control behavior, and real-world design constraints for battery-powered dual-rail systems requiring low-noise, high-PSRR power sequencing.
Technical Context
The MIC5335-SGYMT-TR integrates two independent CMOS-based LDOs with active-high enables (EN1/EN2), each supporting 300 mA continuous output current and operating across 2.3 V to 5.5 V input range. Its µCap architecture eliminates need for large bypass capacitors by enabling stable regulation with just 1 µF ceramic output capacitance per channel.
Thermal design is constrained by θJA = 100°C/W in the TDFN-6 package, with thermal shutdown and current limit (340–950 mA) protecting both regulators. Ground current remains ≤125 µA per enabled LDO up to full load, supporting ultra-low quiescent operation in always-on subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 3.3 V / 1.8 V (fixed, non-adjustable; enables dual-rail SoC core/I/O supply) |
| Dropout Voltage | 75 mV @ 300 mA (enables >97% efficiency at 3.3 VIN → 3.3 VOUT, critical for Li-ion discharge tail) |
| PSRR | 65 dB @ 1 kHz (suppresses switching noise from adjacent DC/DC converters in RF-sensitive receivers) |
| Quiescent Current | 90 µA per LDO (supports <200 µA total system standby when one LDO is active) |
| Output Capacitor | 1 µF ceramic minimum (reduces BOM count and PCB area vs. legacy 10–22 µF tantalum solutions) |
| Enable Logic | Active-high EN1/EN2 (allows independent power-up sequencing of processor core and peripherals) |
| Operating Temp | –40°C to +125°C junction (validated for automotive infotainment and industrial handheld environments) |
Pinout & Package
Package: 6-lead 1.6 mm × 1.6 mm × 0.55 mm Thin DFN (TDFN-6, MT), ePad thermally connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VIN | Input supply rail | Shared input for both LDOs; requires 1 µF ceramic bypass to GND per datasheet layout guidance |
| 2 GND | Power ground reference | Common return for both regulators and ePad; must be low-impedance connection to PCB ground plane |
| 3 EN2 | LDO2 enable control | Active-high logic input; drives 1.8 V rail; floating state prohibited - must tie to GND or VIN |
| 4 EN1 | LDO1 enable control | Active-high logic input; drives 3.3 V rail; supports independent sequencing without external logic |
| 5 VOUT2 | LDO2 regulated output | Delivers stable 1.8 V @ up to 300 mA; connects directly to digital I/O or memory interface supplies |
| 6 VOUT1 | LDO1 regulated output | Delivers stable 3.3 V @ up to 300 mA; powers RF transceivers or analog front-end circuitry |
| EPAD | Exposed thermal pad | Internally connected to GND; mandatory solder connection to PCB thermal plane for θJA = 100°C/W rating |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enables | EN1 and EN2 allow staggered power-up of 3.3 V and 1.8 V rails - avoids simultaneous inrush and meets processor boot timing requirements |
| µCap stability | Stable with 1 µF ceramic output caps per channel - eliminates ESR sensitivity and reduces board area by >70% vs. traditional LDOs |
| Ultra-low dropout | 75 mV @ 300 mA enables operation down to 2.3 V input - extends usable battery life in single-cell Li-ion systems |
| High PSRR | 65 dB @ 1 kHz suppresses ripple from upstream switching regulators - critical for clean power in GPS baseband and audio codecs |
| Thermal protection | Integrated thermal shutdown activates at +125°C junction - prevents damage during sustained 300 mA dual-load operation in sealed enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6216D3318MR-G | 3.3 V / 1.8 V outputs; 150 mA per channel; 120 mV dropout @ 150 mA; SOT-26 package (2.8 mm × 2.9 mm) | Lower current capability limits use in high-speed SDIO or burst-mode imaging; larger footprint increases PCB area by 2.2× | Select when cost sensitivity outweighs size and current requirements; verify thermal margin at 150 mA sustained load. |

FAQ
What are the exact output voltages of the MIC5335-SGYMT-TR?
The MIC5335-SGYMT-TR provides fixed 3.3 V on VOUT1 and 1.8 V on VOUT2, as confirmed by Microchip's Product Identification System (SG = 3.3V/1.8V) and Table 5-1 in DS20006039A. These outputs are factory-trimmed and do not require external feedback resistors - ensuring ±2.0% accuracy over temperature and load.
Can the MIC5335-SGYMT-TR operate with input voltage below 2.3 V?
No - the MIC5335-SGYMT-TR has a specified minimum input voltage of 2.3 V per Absolute Maximum Ratings and Operating Ratings tables. Operation below 2.3 V may cause dropout, regulation loss, or undefined behavior; the 75 mV dropout value applies only at ≥2.3 V input.
Is a separate input capacitor required for the MIC5335-SGYMT-TR?
Yes - a 1 µF ceramic capacitor from VIN to GND is mandatory per Section 4.2 of DS20006039A. This input bypass capacitor stabilizes the regulator against high-frequency noise and ensures transient response integrity, especially when sourced from a switching DC/DC converter.
Does the MIC5335-SGYMT-TR support zero-load operation?
Yes - Section 4.4 confirms the MIC5335-SGYMT-TR remains stable and in regulation with no load, a key advantage for CMOS RAM keep-alive circuits and low-power sleep modes where one or both outputs may be idle while maintaining voltage accuracy.
What is the thermal resistance and maximum power dissipation of the MIC5335-SGYMT-TR?
The MIC5335-SGYMT-TR has θJA = 100°C/W in its TDFN-6 package. At 3.3 VIN, 3.3 V/1.8 V outputs, and 300 mA per channel, calculated power dissipation is 0.39 W. Using Equation 4-2, this yields a maximum ambient temperature of 86°C for reliable operation at full load.
