Product details
Overview
AZ1084D-5.0TRG1 from Diodes Incorporated is a 5.0V fixed-output, 5A low dropout linear regulator in TO-252-2 (3) package with 1.3V typical dropout at full load, thermal shutdown and current limiting, used for post-regulation after switching supplies in embedded processor power rails.
For engineers reviewing the AZ1084D-5.0TRG1 datasheet, AZ1084D-5.0TRG1 pinout, AZ1084D-5.0TRG1 application, or AZ1084D-5.0TRG1 equivalent, this page delivers verified specifications, validated pin functions, confirmed thermal and electrical behavior across temperature, and real-world use context for microprocessor supply design and battery charger output staging.
Technical Context
The AZ1084D-5.0TRG1 implements a trimmed band-gap reference with internal resistor divider to fix VOUT at 5.0V ±1%, operates with input voltage as low as 6.5V (VIN ≥ VOUT + VDROP), and maintains regulation under 0–125°C junction temperature range. Its on-chip thermal limiting activates when die temperature exceeds +150°C, and current limit triggers at 5.5–6.5A.
It features 72dB PSRR at 120Hz with 25µF tantalum output capacitor, 0.015% typical line regulation, and 0.1% typical load regulation - enabling stable 5V rail generation for noise-sensitive analog and digital loads without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0V ±1% (guaranteed over 10mA–5A load and 0–125°C TJ) |
| Dropout Voltage | 1.3V typical at 5A (enables operation with VIN as low as 6.5V) |
| Output Current | 5A continuous (supports high-current microprocessor core or I/O rails) |
| Current Limit | 6.5A typical (provides short-circuit protection without external circuitry) |
| Thermal Shutdown | Activates at +150°C TJ (prevents permanent damage during overload or poor heatsinking) |
| PSRR | 72dB at 120Hz (suppresses ripple from upstream switching converters) |
| Line Regulation | 0.015% typical (ensures <0.75mV output change per 1V input variation) |
| Load Regulation | 0.1% typical (holds output within ±5mV from 10mA to 5A load step) |
Pinout & Package
Package: TO-252-2 (3), surface-mount, lead-free, RoHS-compliant, with exposed thermal pad (pin 2 = OUTPUT tab).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | INPUT | Unregulated DC input (6.5V–10V); connects to upstream supply or filter capacitor |
| 2 | OUTPUT | Regulated 5.0V output; also serves as thermal path via exposed metal tab |
| 3 | GND | Ground reference for internal band-gap and error amplifier; must be low-impedance return |
Key Features

Use Scenario: Final-stage regulation in 5V USB PD or Li-ion charger designs where upstream DC-DC output requires ripple cleanup. IC Role / Device Role / Timing Role: Linear post-regulator smoothing switching ripple before delivery to battery protection IC or USB port. Use Value: 72dB PSRR at 120Hz attenuates residual 100/120Hz ripple from AC-DC adapter or buck controller. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2112K-5.0TRG1 | 2A max output, 350mV dropout at 2A, SOT-25 package | Lower current capacity; unsuitable for >2A loads but smaller footprint | Select if board space is constrained and load ≤2A; not drop-in for 5A requirement |
| TLV1117-50CDCYR | 800mA max, 1.2V dropout at 800mA, SOT-223 package | Lower current, higher dropout, different thermal performance | Use only for low-power subsystems; cannot replace AZ1084D-5.0TRG1 in 5A applications |
Compared with AP2112K-5.0TRG1 and TLV1117-50CDCYR, AZ1084D-5.0TRG1 uniquely delivers 5A continuous current in TO-252-2 (3) with sub-1.5V dropout - making it irreplaceable in high-current, space-constrained linear regulation where thermal pad conduction and load transient stability are critical.

FAQ
Is AZ1084D-5.0TRG1 still in active production?
No - AZ1084D-5.0TRG1 is marked obsolete by Diodes Incorporated (DS36598 Rev. 4, November 2021), with replacement guidance pointing to AZ1084C-series variants. Aetrix Electronics maintains limited legacy stock and supports last-time-buy programs with full traceability and documentation for ongoing production needs.
What is the thermal resistance θJA for AZ1084D-5.0TRG1 in TO-252-2 (3)?
The datasheet specifies θJA = 100°C/W for TO-252-2 (3), TO-252-2 (4), and TO-252-2 (5) packages. This value assumes standard JEDEC 2-layer PCB layout with 1-inch² copper pour under the thermal pad; actual performance improves with enhanced copper area or thermal vias.
Can AZ1084D-5.0TRG1 be used without an input capacitor?
No - the datasheet mandates a minimum 10µF input ceramic or tantalum capacitor (low-ESR) close to the INPUT pin to prevent oscillation and ensure stability under fast load transients. Omission risks instability, overshoot, or thermal shutdown during startup.
Does AZ1084D-5.0TRG1 require an external diode for reverse-voltage protection?
No - the device includes internal reverse-battery protection and does not require an external blocking diode. However, an external Schottky diode from OUTPUT to INPUT is recommended if the output may be driven higher than input (e.g., during hot-swap or backup battery scenarios) to prevent reverse current flow through the pass element.
