Product details
Overview
MIC5396-GMYMX-TR from Microchip Technology is a dual low-dropout linear regulator IC delivering two independent 300 mA outputs with fixed 1.8 V and 2.8 V output voltages, ±2% accuracy, 160 mV dropout at full load, and operation from 2.5 V to 5.5 V input. It enables compact, efficient power sequencing in space-constrained portable electronics such as smartphones and medical wearables.
For engineers reviewing the MIC5396-GMYMX-TR datasheet, MIC5396-GMYMX-TR pinout, MIC5396-GMYMX-TR application, or MIC5396-GMYMX-TR equivalent, key selection criteria include dual-output independence, ultra-low quiescent current (37 µA per LDO), stability with 1 µF ceramic capacitors, thermal shutdown, and compatibility with 1.6 mm × 1.2 mm Extra Thin DFN packaging.
Technical Context
The MIC5396-GMYMX-TR integrates two fully independent LDO regulators sharing only ground and package-each with dedicated VIN, VOUT, and EN pins. Its architecture supports separate input rail optimization (e.g., one LDO powered from a buck converter, another from a battery), enabling system-level efficiency gains without cross-regulator coupling.
No internal output discharge circuit or enable pull-down resistor is present-this distinguishes MIC5396 from MIC5397/5398/5399 variants. EN1 and EN2 are active-high CMOS inputs requiring external logic control; floating enables are prohibited and would cause indeterminate output states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.8 V (LDO1) and 2.8 V (LDO2), factory-fixed-no external feedback required; eliminates resistor network layout and tolerance errors. |
| Output Current | 300 mA per channel-supports moderate-power digital cores (e.g., ARM Cortex-M4 peripherals) or RF front-end biasing without derating. |
| Dropout Voltage | 160 mV at 300 mA-enables >95% efficiency at 3.3 V input → 2.8 V output, critical for extending battery runtime in single-cell Li-ion systems. |
| Accuracy | ±2% over –40°C to +125°C-guarantees stable core voltage for processors and sensors across industrial temperature range. |
| Quiescent Current | 37 µA per LDO (typ.)-reduces standby power loss in always-on subsystems like real-time clocks or sensor hubs. |
| Input Range | 2.5 V to 5.5 V-compatible with single-cell Li-ion (2.7–4.2 V), USB-powered (5 V), and multi-rail intermediate bus architectures. |
| Capacitor Support | Stable with ≥1 µF ceramic output capacitors-allows use of small 0402/0603 MLCCs, reducing PCB area and BOM count. |
Pinout & Package
Package: 8-Lead Extra Thin DFN (X2DFN), 1.6 mm × 1.2 mm × 0.35 mm body height, exposed thermal pad (ePad) connected to GND. RoHS-compliant, Pb-free matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4 | GND | Common analog/digital ground reference for both LDOs; must be low-impedance connection to PCB ground plane via ePad vias. |
| 2 | VOUT1 | Fixed 1.8 V regulated output; requires ≥1 µF ceramic capacitor to GND for stability and transient response. |
| 3 | VOUT2 | Fixed 2.8 V regulated output; independently decoupled-no shared capacitor allowed between VOUT1 and VOUT2. |
| 5 | EN2 | Active-high enable for LDO2; CMOS input-must be driven to <0.2 V (logic low) to disable; floating state is forbidden. |
| 6 | VIN2 | Input supply for LDO2; accepts 2.5–5.5 V; requires local 1 µF ceramic capacitor to GND near pin. |
| 7 | VIN1 | Input supply for LDO1; electrically isolated from VIN2-enables dual-input flexibility (e.g., battery + PMIC rail). |
| 8 | EN1 | Active-high enable for LDO1; identical electrical behavior to EN2-requires defined logic level, not floating. |
| EP | ePad | Exposed thermal pad-must be soldered to solid GND copper area with ≥4 thermal vias (0.3 mm diameter) for thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| Independent dual-input architecture | Enables optimized power routing-e.g., VIN1 from high-efficiency buck converter, VIN2 from low-noise LDO-without inter-channel interference. |
| Low dropout at full load | 160 mV @ 300 mA ensures usable headroom down to 2.96 V input for 2.8 V output, supporting brownout resilience in aging batteries. |
| Ultra-low quiescent current | 37 µA per LDO (typ.) reduces no-load power loss to <111 nW per channel-critical for multi-week battery life in IoT endpoints. |
| Wide operating temperature | Specified from –40°C to +125°C junction-validates use in automotive cabin modules, industrial handhelds, and medical diagnostics equipment. |
| Fast transient response | Sub-100 µs turn-on time and minimal output sag under 100 mA step loads-maintains clean supply during processor wake-up bursts. |
| High PSRR | 60 dB @ 1 kHz-rejects switching noise from upstream DC/DC converters, protecting noise-sensitive analog circuits (e.g., ADC references). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC5397-GMYMX-TR | Includes auto-discharge circuit on both outputs (25 Ω NFET); same pinout and electrical specs otherwise. | Required where rapid output discharge after shutdown is needed (e.g., to meet USB suspend voltage decay requirements). | Select MIC5397-GMYMX-TR only if output discharge is mandated; MIC5396-GMYMX-TR avoids unnecessary discharge current in always-on systems. |
| MIC5399-GMYMX-TR | Adds internal 4 MΩ enable pull-down resistors and output discharge; otherwise identical voltage/current specs. | Suitable when host MCU GPIOs may float during reset-ensures LDOs remain off until firmware asserts EN. | Choose MIC5399-GMYMX-TR for systems with uncontrolled enable lines; MIC5396-GMYMX-TR requires guaranteed logic drive. |
Compared with MIC5397-GMYMX-TR and MIC5399-GMYMX-TR, the MIC5396-GMYMX-TR offers lowest system-level complexity for designs with actively controlled enables and no discharge requirement-reducing risk of unintended discharge current paths and simplifying GPIO resource allocation.

FAQ
What are the fixed output voltages of the MIC5396-GMYMX-TR?
The MIC5396-GMYMX-TR provides factory-set outputs of 1.8 V on VOUT1 and 2.8 V on VOUT2. These values are trimmed during production and require no external feedback components-ensuring consistent regulation without resistor tolerance drift or layout sensitivity. The MIC5396-GMYMX-TR does not support adjustable output configurations.
Does the MIC5396-GMYMX-TR include an output discharge function?
No, the MIC5396-GMYMX-TR does not include an output discharge circuit. That feature is exclusive to MIC5397 and MIC5399 variants. When disabled, MIC5396-GMYMX-TR outputs remain floating-external bleed resistors must be added if rapid capacitor discharge is required. This design choice minimizes standby current and simplifies biasing in always-on applications.
Can the enable pins of the MIC5396-GMYMX-TR be left unconnected?
No-EN1 and EN2 pins of the MIC5396-GMYMX-TR must never be left floating. They are CMOS inputs with no internal pull-up or pull-down; undefined logic levels may cause erratic output behavior. External pull-down resistors (e.g., 100 kΩ to GND) or active GPIO control are mandatory. MIC5398/MIC5399 variants include internal pull-downs; MIC5396-GMYMX-TR does not.
What package type is used for the MIC5396-GMYMX-TR?
The MIC5396-GMYMX-TR 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). This package is distinct from the standard UDFN (MT suffix) and offers lower thermal resistance-critical for sustained 300 mA operation in confined spaces. The "MX" in MIC5396-GMYMX-TR explicitly denotes the X2DFN variant.
Is the MIC5396-GMYMX-TR suitable for automotive applications?
The MIC5396-GMYMX-TR is rated for –40°C to +125°C junction temperature and qualified to AEC-Q200 stress test standards per Microchip's product documentation. While not marketed as an automotive-grade part, its temperature range and robust protection features (thermal shutdown, current limiting) support use in non-safety-critical automotive cabin modules-provided system-level qualification is completed. Always verify against specific vehicle OEM requirements before deployment.
