Product details
Overview
MIC5335-PJYMT-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 3.0 V and 2.5 V outputs. It operates from 2.3 V to 5.5 V input, achieves 75 mV dropout at 300 mA per channel, and maintains stability with only 1 µF ceramic output capacitors-enabling compact power delivery in space-constrained portable media players and GPS receivers.
For engineers reviewing the MIC5335-PJYMT-TR datasheet, MIC5335-PJYMT-TR pinout, MIC5335-PJYMT-TR application, or MIC5335-PJYMT-TR equivalent, this page provides verified technical context, validated pin functions, confirmed dual-LDO operating parameters, thermal performance data for 100°C/W θJA, and real-world design implications of independent enable control and µCap stability.
Technical Context
The MIC5335-PJYMT-TR integrates two independent CMOS-based LDO regulators sharing a common VIN and GND, each with dedicated active-high enable inputs (EN1/EN2) and thermally isolated output paths. Its architecture supports simultaneous or staggered turn-on (30 µs typical), zero-load regulation, and no-bypass-capacitor operation due to high PSRR (65 dB @ 1 kHz) and low noise (90 µVRMS).
Thermal management relies on the exposed EPAD tied to ground and a specified junction-to-ambient thermal resistance of 100°C/W. The device implements independent current limit protection (340–950 mA) and thermal shutdown, with ground current as low as 90 µA per enabled LDO and 0.01 µA in full shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | Fixed 3.0 V (VOUT1) and 2.5 V (VOUT2); eliminates external feedback resistors and ensures ±2% accuracy over –40°C to +125°C. |
| Dropout Voltage | 75 mV @ 300 mA per LDO; enables regulation from 3.3 V input down to 3.0 V/2.5 V outputs with minimal headroom loss. |
| PSRR | 65 dB @ 1 kHz; suppresses switching noise from upstream DC/DC converters without requiring large bypass capacitors. |
| Output Capacitance | Stable with ≥1 µF X7R/X5R ceramic capacitor; reduces PCB area and BOM cost versus traditional LDOs needing ≥10 µF. |
| Quiescent Current | 90 µA per enabled LDO; extends battery life in always-on subsystems like GPS baseband or camera sensor bias rails. |
| Enable Control | Independent EN1/EN2 active-high logic inputs; allows dynamic power sequencing-e.g., enabling RF section before baseband core. |
| Thermal Protection | Integrated thermal shutdown triggers at TJ > +125°C; prevents permanent damage during sustained 300 mA loads in confined layouts. |
Pinout & Package
Package: 6-lead Thin DFN (TDFN-6, MT), 1.6 mm × 1.6 mm × 0.55 mm, with exposed EPAD thermally and electrically 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 for stability and noise rejection. |
| 2 - GND | Power and signal reference ground | Shared return path for both LDOs; connects internally to EPAD for optimal thermal conduction. |
| 3 - EN2 | LDO2 enable control input | Active-high logic; drives VOUT2 when ≥1.1 V; <0.2 V disables LDO2 and reduces ground current to 0.01 µA. |
| 4 - EN1 | LDO1 enable control input | Active-high logic; independently controls VOUT1; floating state is prohibited and may cause erratic output behavior. |
| 5 - VOUT2 | Regulated 2.5 V output | Delivers up to 300 mA; requires ≥1 µF ceramic capacitor to GND; stable under zero-load conditions. |
| 6 - VOUT1 | Regulated 3.0 V output | Delivers up to 300 mA; supports fast load transient response (see Fig 2-11); immune to output capacitor ESR variations. |
| EPAD | Exposed thermal pad | Internally connected to GND; must be soldered to PCB copper pour for thermal dissipation and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDOs | Enables split-rail power for mixed-signal SoCs-e.g., 3.0 V analog front-end and 2.5 V digital core-with separate enable timing. |
| µCap stability | Guaranteed stability with 1 µF ceramic output capacitors, reducing total solution size by >50% vs. legacy LDOs requiring 10–22 µF tantalum. |
| High PSRR at 1 kHz | 65 dB attenuation of ripple from noisy switchers, eliminating need for additional LC filtering stages in RF-sensitive GPS receiver chains. |
| Ultra-low quiescent current | 90 µA per active LDO supports multi-week battery life in portable media players during standby with partial subsystem wake-up. |
| Fast 30 µs turn-on | Meets tight power-up sequencing requirements in camera modules where sensor bias rails must stabilize before clock enable. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6216D302MR-G | Single-channel 300 mA LDO; 3.0 V fixed output only; no second output or EN2 pin. | Requires separate regulator for 2.5 V rail; increases BOM count and layout area. | Select when only one regulated rail is needed and space permits discrete implementation. |
| Richtek RT9013-25PU5 | Single-channel 300 mA LDO; 2.5 V fixed output; lacks independent enable and µCap optimization for 1 µF stability. | Needs ≥2.2 µF output capacitance; higher ground current (120 µA) reduces battery runtime. | Choose for cost-sensitive designs where dual-rail integration is not required and PSRR >60 dB is not critical. |
Compared with MIC5335-PJYMT-TR, the XC6216D302MR-G and RT9013-25PU5 each provide only one fixed output voltage and lack independent enable control-making them unsuitable for applications requiring coordinated dual-rail power sequencing or space-constrained dual-voltage systems.

FAQ
What are the fixed output voltages of the MIC5335-PJYMT-TR?
The MIC5335-PJYMT-TR provides two fixed output voltages: 3.0 V on VOUT1 (pin 6) and 2.5 V on VOUT2 (pin 5). These values are factory-trimmed and guaranteed within ±2% accuracy across –40°C to +125°C operating temperature, as confirmed in Table 5-1 and Electrical Characteristics sections of DS20006039A.
Can the MIC5335-PJYMT-TR operate with no load on either output?
Yes, the MIC5335-PJYMT-TR remains stable and in regulation with zero load on either or both outputs-a feature explicitly documented in Section 4.4 "No-Load Stability." This capability supports applications like CMOS RAM keep-alive circuits where one rail may be idle while the other powers active circuitry.
What is the minimum recommended output capacitor for the MIC5335-PJYMT-TR?
The MIC5335-PJYMT-TR requires a minimum 1 µF X7R or X5R ceramic capacitor on each output (VOUT1 and VOUT2) for guaranteed stability, as stated in Section 4.3 "Output Capacitor" and validated in the Electrical Characteristics table. Larger values do not improve performance significantly and are not required.
Does the MIC5335-PJYMT-TR include thermal protection?
Yes, the MIC5335-PJYMT-TR integrates thermal shutdown protection that activates when junction temperature exceeds +125°C, as specified in Absolute Maximum Ratings and Functional Block Diagram. Recovery occurs automatically once die temperature falls below the hysteresis threshold, ensuring robust operation under overload or poor heatsinking conditions.
What package type and dimensions does the MIC5335-PJYMT-TR use?
The MIC5335-PJYMT-TR uses a 6-lead Thin DFN (TDFN-6, MT) package measuring 1.6 mm × 1.6 mm × 0.55 mm with an exposed EPAD. This footprint is confirmed in Package Type diagrams (DS20006039A-page 2), Package Outline (page 13), and Product Identification System (page 17).
