Product details
Overview
MIC5335-SJYMT-TR from Microchip Technology is a dual-channel, 300 mA ultra-low dropout (ULDO) linear regulator in a 1.6 mm × 1.6 mm TDFN-6 package, delivering fixed 3.3 V and 2.5 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. It serves as a compact, high-efficiency power supply for RF receiver chains and digital baseband sections in portable wireless devices.
For engineers reviewing the MIC5335-SJYMT-TR datasheet, MIC5335-SJYMT-TR pinout, MIC5335-SJYMT-TR application, or MIC5335-SJYMT-TR equivalent, this page delivers verified electrical specs, thermal performance data, independent enable control behavior, dual-LDO stability conditions, and real-world use cases in GPS receivers and mobile media subsystems - all confirmed from Microchip's DS20006039A.
Technical Context
The MIC5335-SJYMT-TR integrates two independent CMOS-based ULDO regulators sharing a common VIN and GND, each with active-high enable (EN1/EN2), thermal shutdown, and current limit protection. Its µCap architecture eliminates need for large bypass capacitors by enabling stable operation with just 1 µF ceramic output capacitance per channel.
Designed for thermally constrained portable systems, it achieves 100°C/W junction-to-ambient thermal resistance in its 1.6 mm × 1.6 mm TDFN-6 package and supports full 300 mA load per LDO across –40°C to +125°C junction temperature range. Input voltage range is 2.3 V to 5.5 V, with dropout defined at 2% VOUT deviation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 3.3 V (VOUT1) and 2.5 V (VOUT2), fixed, ±2% accuracy over temperature |
| Max Output Current | 300 mA per LDO - supports simultaneous dual-rail loads without derating |
| Dropout Voltage | 75 mV @ 300 mA - enables regulation down to VIN = VOUT + 0.075 V, critical for battery-powered 3.3 V/2.5 V systems |
| PSRR | 65 dB @ 1 kHz - suppresses switching noise from upstream DC/DC converters feeding RF/analog circuitry |
| Quiescent Current | 90 µA per LDO - minimizes standby power in always-on GPS or sensor subsystems |
| Enable Logic | Active-high EN1/EN2 with <0.2 V low threshold and >1.1 V high threshold - compatible with 1.8 V/3.3 V GPIO |
| Stability Capacitor | 1 µF ceramic per output - reduces PCB area vs. traditional 10–22 µF tantalum solutions |
Pinout & Package
Package: 6-lead Thin DFN (TDFN-6, MT), 1.6 mm × 1.6 mm × 0.55 mm, exposed thermal pad (EPAD) internally connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Common input supply rail | Accepts 2.3–5.5 V; must be bypassed with ≥1 µF ceramic capacitor to GND |
| 2 - GND | Power and signal reference ground | Shared return path for both LDOs; EPAD soldered to PCB ground plane for thermal relief |
| 3 - EN2 | LDO2 enable control input | Active-high logic; drives VOUT2 on/off independently; must not float - tie to GND or MCU GPIO |
| 4 - EN1 | LDO1 enable control input | Active-high logic; drives VOUT1 on/off independently; enables sequencing of 3.3 V before 2.5 V rails |
| 5 - VOUT2 | Regulated 2.5 V output | Delivers up to 300 mA; requires ≥1 µF ceramic capacitor to GND for stability |
| 6 - VOUT1 | Regulated 3.3 V output | Delivers up to 300 mA; decoupled separately from VOUT2 to prevent cross-talk in mixed-signal designs |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable pins | EN1 and EN2 allow precise power sequencing - e.g., enable 3.3 V rail first, then 2.5 V after stabilization |
| µCap stability | Operates stably with only 1 µF ceramic output capacitors per LDO, cutting board space and BOM cost vs. legacy LDOs |
| High PSRR at 1 kHz | 65 dB rejection enables clean analog/RF power delivery even when sharing input with noisy digital DC/DC converters |
| Ultra-low dropout | 75 mV @ 300 mA preserves headroom in single-cell Li-ion (3.0–3.6 V) or 3.3 V system designs |
| Thermal & current protection | Integrated thermal shutdown and 340–950 mA current limiting per LDO prevent damage during overload or poor heatsinking |
Applications

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 XC6223D332MR-G | Single-output 3.3 V LDO; no 2.5 V rail; 200 mA max; 150 mV dropout @ 200 mA | Requires separate 2.5 V regulator; higher dropout limits usable input range | Select only if dual-rail integration is unnecessary and board space permits two ICs |
| Ricoh RP512K2533D-TR-F | Dual-output (2.5 V/3.3 V), 200 mA per channel, 250 mV dropout @ 200 mA, SOT-26 package | Larger footprint (2.8 mm × 2.9 mm); lower current and higher dropout reduce margin in high-load GPS apps | Consider for cost-sensitive designs where 300 mA load and ultra-low dropout are not required |
Compared with MIC5335-SJYMT-TR, the XC6223D332MR-G lacks integrated dual-rail capability and requires additional components for 2.5 V supply, while the RP512K2533D-TR-F trades off 100 mA per channel and 175 mV higher dropout for lower unit cost - making MIC5335-SJYMT-TR optimal for space-constrained, high-performance portable RF systems.

FAQ
What are the exact output voltages of the MIC5335-SJYMT-TR?
The MIC5335-SJYMT-TR provides fixed 3.3 V on VOUT1 and 2.5 V on VOUT2, as confirmed by Microchip's Package Marking Table 5-1 (SPJ marking) and Electrical Characteristics section. Output voltage accuracy is ±2% over temperature (–40°C to +125°C), with load regulation of ≤2.0% from 100 µA to 300 mA per channel. These values are factory-trimmed and do not require external feedback resistors.
Does the MIC5335-SJYMT-TR require external capacitors for stability?
Yes - the MIC5335-SJYMT-TR requires a minimum 1 µF ceramic capacitor from each output (VOUT1 and VOUT2) to GND for stability, as specified in Section 4.3 of DS20006039A. An additional 1 µF ceramic capacitor is required from VIN to GND. X7R or X5R dielectric types are recommended; Y5V/Z5U capacitors are discouraged due to excessive capacitance drift over temperature.
Can the two LDOs in the MIC5335-SJYMT-TR be enabled independently?
Yes - the MIC5335-SJYMT-TR features independent active-high enable inputs: EN1 controls VOUT1 (3.3 V) and EN2 controls VOUT2 (2.5 V). Each pin has a logic-low threshold <0.2 V and logic-high threshold >1.1 V, supporting direct interfacing with 1.8 V or 3.3 V GPIO. Section 4.1 explicitly states that floating enable pins must be avoided to prevent indeterminate output states.
What is the thermal performance of the MIC5335-SJYMT-TR under full load?
At 300 mA per LDO with VIN = 3.3 V, VOUT1 = 3.3 V, and VOUT2 = 2.5 V, the MIC5335-SJYMT-TR dissipates 0.39 W. With θJA = 100°C/W, the maximum ambient temperature for safe operation is 86°C (calculated per Equation 4-3, DS20006039A page 10). The exposed thermal pad (EPAD) must be soldered to a PCB ground plane to achieve this rating.
Is the MIC5335-SJYMT-TR compatible with lead-free reflow processes?
Yes - the MIC5335-SJYMT-TR uses a Pb-free 6-lead TDFN package with Matte Tin (Sn) plating, rated for JEDEC-standard lead-free reflow profiles. The absolute maximum lead temperature is +260°C for 3 seconds (DS20006039A page 3), and the device complies with RoHS Directive 2011/65/EU as indicated by the 'Y' junction temperature suffix in the part number.
