Product details
Overview
MIC5398-P4YMX-T5 from Microchip Technology is a dual low-dropout linear regulator (LDO) with independent 300 mA outputs, fixed output voltages of 3.0 V and 1.2 V, ±2% output accuracy, and 160 mV dropout at full load. It features internal enable pull-down resistors on both EN pins, operates from 2.5 V to 5.5 V input, and is optimized for space-constrained portable electronics requiring dual-rail power sequencing.
For engineers reviewing the MIC5398-P4YMX-T5 datasheet, MIC5398-P4YMX-T5 pinout, MIC5398-P4YMX-T5 application, or MIC5398-P4YMX-T5 equivalent, key selection considerations include its 1.6 mm × 1.2 mm Extra Thin DFN package, zero-off-state shutdown current (0.05 µA), stable operation with 1 µF ceramic output capacitors, and thermal shutdown/current limit protection for battery-powered systems.
Technical Context
The MIC5398-P4YMX-T5 integrates two fully independent LDO regulators sharing only ground and package-each with dedicated VIN, VOUT, and EN pins. Its architecture supports asynchronous enable control, allowing one regulator to remain active while the other is disabled without cross-coupling effects.
Unlike MIC5396/MIC5397 variants, MIC5398 includes internal 4 MΩ pull-down resistors on EN1 and EN2, ensuring reliable disable state during tri-stated control signals. It does not include output discharge circuitry (a feature exclusive to MIC5397/MIC5399), confirming its role as a pull-down–optimized dual LDO without auto-discharge functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.0 V / 1.2 V (fixed, non-adjustable; enables direct powering of core + I/O rails) |
| Max Output Current | 300 mA per channel (supports dual-core SoC subsystems or mixed-signal ASICs) |
| Dropout Voltage | 160 mV at 300 mA (enables >95% efficiency at 3.3 V input → 3.0 V rail) |
| Accuracy | ±2% over –40°C to +125°C (meets tight tolerance requirements for memory and logic supply rails) |
| Quiescent Current | 37 µA per LDO (typ.) in active mode; 0.05 µA total in shutdown (extends battery life in standby) |
| Input Range | 2.5 V to 5.5 V (compatible with single-cell Li-ion, Li-poly, or 3.3 V/5 V system rails) |
| PSRR | 60 dB at 1 kHz (suppresses switching noise from upstream DC-DC converters) |
Pinout & Package
Package: 8-Lead Extra Thin DFN (X2DFN), 1.6 mm × 1.2 mm × 0.35 mm body, exposed thermal pad (ePad) connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4 | GND | Common analog/digital ground reference; ePad must be soldered to PCB ground plane for thermal and EMI performance |
| 2 | VOUT1 | 3.0 V regulated output; requires ≥1 µF ceramic capacitor to ground for stability |
| 3 | VOUT2 | 1.2 V regulated output; independent from VOUT1; decoupling required per datasheet layout guidelines |
| 5 | EN2 | Active-high enable for VOUT2; internal 4 MΩ pull-down ensures OFF state when unconnected or floating |
| 6 | VIN2 | Input supply for 1.2 V LDO; separate from VIN1 to allow different source domains (e.g., battery vs. PMIC rail) |
| 7 | VIN1 | Input supply for 3.0 V LDO; supports independent voltage optimization per channel |
| 8 | EN1 | Active-high enable for VOUT1; internal 4 MΩ pull-down eliminates need for external pull-down resistor |
| EP | ePad | Thermal and electrical ground connection; mandatory for thermal dissipation and noise reduction |
Key Features
| Feature | Design Value |
|---|---|
| Independent Enable Pull-Down | 4 MΩ internal resistor on EN1/EN2 ensures fail-safe disable without external components |
| Ultra-Low Shutdown Current | 0.05 µA total (both LDOs off) minimizes battery drain in deep sleep modes |
| Stable with 1 µF Ceramic Capacitors | Eliminates need for larger or higher-ESR capacitors-reduces BOM count and board area |
| Thermal & Current Protection | Integrated thermal shutdown and 400–900 mA current limiting prevent damage under fault conditions |
| Wide Operating Temperature | Rated for –40°C to +125°C junction temperature-suitable for automotive cabin and industrial edge applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC5396-P4YMX-T5 | No internal enable pull-down; EN pins require external pull-down for safe default-OFF behavior | Suitable where control logic guarantees defined EN states; less robust against floating inputs | Select when external pull-downs are already present or system-level control ensures deterministic EN states |
| MIC5399-GMYMX-T5 | Includes both internal enable pull-down AND output discharge circuit (25 Ω NFET); higher ground current in active mode (42 µA typ. per LDO) | Required where rapid VOUT discharge after disable is needed (e.g., to meet reset timing specs) | Choose only if auto-discharge is mandatory; otherwise MIC5398 offers lower IQ and same pull-down reliability |
Compared with MIC5396-P4YMX-T5, MIC5398-P4YMX-T5 eliminates external pull-down components and improves system robustness; compared with MIC5399-GMYMX-T5, it reduces quiescent current by ~13% and removes unnecessary discharge circuitry-optimizing for lowest power in always-on edge nodes.

FAQ
What output voltages does the MIC5398-P4YMX-T5 provide?
The MIC5398-P4YMX-T5 provides fixed output voltages of 3.0 V on VOUT1 and 1.2 V on VOUT2. These values are laser-trimmed during manufacturing and are not adjustable via external resistors. The "P4" in the part number explicitly denotes the 3.0 V / 1.2 V configuration per Microchip's Product Identification System.
Does the MIC5398-P4YMX-T5 include output discharge circuitry?
No, the MIC5398-P4YMX-T5 does not include output discharge circuitry. That feature is exclusive to MIC5397 and MIC5399 variants. MIC5398 is distinguished by its internal enable pull-down resistors (4 MΩ) on both EN1 and EN2, but lacks the 25 Ω auto-discharge NFET found in MIC5397/MIC5399.
What package type is used for the MIC5398-P4YMX-T5?
The MIC5398-P4YMX-T5 uses an 8-Lead Extra Thin DFN (X2DFN) package measuring 1.6 mm × 1.2 mm × 0.35 mm, with an exposed thermal pad (ePad). The "MX" suffix in the part number confirms the X2DFN variant, distinct from the standard UDFN ("MT") package.
Can the MIC5398-P4YMX-T5 operate with input voltages below 2.5 V?
No, the MIC5398-P4YMX-T5 has a specified minimum input voltage of 2.5 V per Absolute Maximum and Operating Ratings. Operation below this level is not guaranteed and may result in regulation loss, increased dropout, or undefined behavior. The 160 mV dropout spec applies only within the 2.5 V–5.5 V operating range.
Is the MIC5398-P4YMX-T5 suitable for automotive applications?
Yes-the MIC5398-P4YMX-T5 is rated for a junction temperature range of –40°C to +125°C and is RoHS-compliant, making it suitable for under-hood and cabin automotive applications where dual-rail LDO capability and thermal resilience are required. However, it is not AEC-Q200 qualified; system-level qualification remains the customer's responsibility.
