Product details
Overview
AZ1084D-5.0TRE1 from Diodes Incorporated is a fixed-output 5.0V, 5A low dropout linear regulator in TO-252-2 (3) package with 1.3V typical dropout at full load, integrated thermal limiting and current limiting (6.5A), and ±1% output voltage accuracy over 0°C to +125°C junction temperature range. It serves as a post-regulator for switching supplies and microprocessor core supply in desktop PCs and embedded systems.
For engineers reviewing the AZ1084D-5.0TRE1 datasheet, AZ1084D-5.0TRE1 pinout, AZ1084D-5.0TRE1 application, or AZ1084D-5.0TRE1 equivalent, key selection criteria include dropout voltage at 5A, thermal resistance (θJA = 100°C/W), load regulation (≤20mV), line regulation (≤10mV), and compatibility with standard TO-252-2 PCB footprints.
Technical Context
The AZ1084D-5.0TRE1 employs a trimmed band-gap reference and on-chip current-limiting circuitry to maintain stable 5.0V output under varying input (6.5–10V) and load (0–5A) conditions. Its architecture integrates thermal shutdown triggered by junction temperature exceeding +150°C.
Designed for high-current linear regulation, it delivers 5A continuous output with 1.3V typical dropout and supports input-to-output differentials as low as 1.5V while maintaining ≤0.1% load regulation and 60dB PSRR at 120Hz - critical for noise-sensitive microprocessor supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0V ±1% (guaranteed across 0–5A load and 0°C to +125°C TJ) |
| Dropout Voltage | 1.3V typical at 5A (enables operation with VIN as low as 6.3V) |
| Output Current | 5A continuous (supports high-power SoC and FPGA core rails) |
| Current Limit | 6.5A (protects against short-circuit and overload without external components) |
| Thermal Resistance | θJA = 100°C/W (TO-252-2 package; requires minimal copper area for thermal management) |
| Line Regulation | ≤10mV over 6.5–10V input (ensures stable VOUT during input ripple or sag) |
| Load Regulation | ≤20mV from 0 to 5A (maintains tight voltage tolerance under dynamic CPU load changes) |
Pinout & Package
Package: TO-252-2 (3), surface-mount, lead-free, RoHS-compliant, with exposed thermal pad (pin 2 = OUTPUT/TAB). Pin 1 = INPUT, Pin 2 = OUTPUT (tab-connected), Pin 3 = GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | INPUT | Unregulated input supply (6.5–10V); connects to bulk capacitor and upstream converter |
| 2 | OUTPUT | Regulated 5.0V output; tab is electrically connected to output and serves as primary thermal path |
| 3 | GND | Ground reference for internal band-gap and error amplifier; must be low-impedance return path |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout voltage | 1.3V typical at 5A enables use with low-headroom inputs (e.g., 7V bus after buck stage) |
| Integrated protection | Thermal shutdown + current limiting eliminate need for external fault-handling circuitry |
| High accuracy output | ±1% initial tolerance and ≤0.5% temperature drift ensure compliance with 5V ±5% system specs |
| Lead-free & green packaging | TO-252-2 (3) meets RoHS 2 and halogen/antimony-free "Green" requirements (Br+Cl <1500ppm) |
| Stable with ceramic output caps | Compatible with ≥10µF X5R/X7R ceramics (per typical application circuit), reducing board space vs. tantalum |
Applications
| Desktop PC Power Delivery | Embedded Microprocessor Core Supply |
|---|---|
|
Use Scenario: Providing clean 5V rail to legacy I/O controllers and peripheral interfaces in ATX-based desktop motherboards. IC Role / Device Role / Timing Role: Post-regulator following a multi-phase buck converter; maintains tight voltage tolerance during burst-mode loads. Use Value: 1.3V dropout allows operation from 6.3V intermediate bus, reducing power loss versus higher-dropout alternatives. |
Use Scenario: Delivering stable 5V to ARM Cortex-A series SoCs and FPGA configuration logic in industrial gateways. IC Role / Device Role / Timing Role: Primary core supply regulator; handles rapid load transients up to 5A with <100mV undershoot. Use Value: 60dB PSRR at 120Hz suppresses switching noise from upstream DC/DC, preventing logic errors. |
| Battery Charger Auxiliary Rail | Post-Regulation for Switching Supplies |
|
Use Scenario: Generating isolated 5V bias for charger IC control circuitry and status LEDs in Li-ion fast-charging adapters. IC Role / Device Role / Timing Role: Low-noise auxiliary regulator powered from main DC bus; operates continuously during charge cycles. Use Value: RMS output noise of 0.003% of VOUT ensures accurate ADC readings for battery voltage monitoring. |
Use Scenario: Tightening output voltage tolerance of a 6.5V buck converter feeding sensitive analog subsystems. IC Role / Device Role / Timing Role: Precision linear post-regulator; compensates for buck converter line/load regulation limitations. Use Value: ≤10mV line regulation and ≤20mV load regulation achieve ±0.2% total output variation - tighter than standalone buck. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 5V, 5A LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP7361-50SAG-7 (Diodes Inc.) | 300mA max output, SOT-25 package, 300mV dropout at 300mA | Not suitable for >1A loads; intended for low-power peripherals only | Select only for space-constrained, low-current auxiliary rails - not a functional replacement. |
| TLV1117-50CDCYR (TI) | 800mA max output, SOT-223, 1.2V dropout at 800mA, no current limit | Lacks overcurrent protection and thermal shutdown; requires external current sense | Use only in thermally managed, low-power designs where fault protection is handled externally. |
Compared with AZ1084D-5.0TRE1, AP7361-50SAG-7 sacrifices 94% output current capacity for footprint reduction, while TLV1117-50CDCYR trades integrated protection and thermal robustness for lower cost in sub-1A applications - neither matches the 5A/1.3V-drop/thermal-shutdown triad of the AZ1084D-5.0TRE1.

FAQ
What is the maximum input voltage rating for AZ1084D-5.0TRE1?
The absolute maximum input voltage is 12V per the datasheet's Absolute Maximum Ratings table. However, the Recommended Operating Conditions specify a maximum of 10V for reliable operation across the full temperature range. Exceeding 10V risks accelerated degradation and violates guaranteed electrical specifications.
Does AZ1084D-5.0TRE1 require an external capacitor on the ADJ/GND pin?
No - the AZ1084D-5.0TRE1 is a fixed-output variant; its feedback resistors are integrated internally. Pin 3 is GND, not ADJ. The ADJ pin only exists on adjustable versions (e.g., AZ1084D-ADJTRE1); this part has no adjustment capability and operates solely as a 5.0V regulator.
Can AZ1084D-5.0TRE1 be paralleled for higher current?
No - the AZ1084D-5.0TRE1 lacks built-in current-sharing circuitry or matching tolerance guarantees. Paralleling introduces imbalance due to output voltage mismatch (±1%), leading to unequal current distribution and potential thermal runaway. Use a single unit rated for the full load.
Is AZ1084D-5.0TRE1 still in active production?
No - the datasheet explicitly states "OBSOLETE – PART DISCONTINUED" and recommends migration to the AZ1084C series. However, Aetrix Electronics maintains limited legacy inventory and offers lifecycle support including cross-reference guidance and drop-in compatible alternatives upon request.
