Product details
Overview
AZ1117CD-5.0TRG1 from Diodes Incorporated is a fixed-output 5.0V low-dropout linear regulator in TO252-2 (3) package, delivering up to 1.35A output current with ±1% output voltage accuracy, 1.3V typical dropout at 0.8A, and 70dB PSRR at 120Hz - optimized for USB devices and PC motherboard power rails where input headroom and transient response are constrained.
For engineers reviewing the AZ1117CD-5.0TRG1 datasheet, AZ1117CD-5.0TRG1 pinout, AZ1117CD-5.0TRG1 application, or AZ1117CD-5.0TRG1 equivalent, key selection criteria include dropout voltage under load, thermal shutdown threshold (+160°C), compatibility with low-ESR ceramic capacitors (<20Ω), minimum 10µF output capacitance requirement, and junction temperature range (-20°C to +125°C).
Technical Context
The AZ1117CD-5.0TRG1 integrates a trimmed bandgap reference and on-chip thermal shutdown circuitry, with current-limit protection set at 1.35A typical. Its architecture uses internal feedback resistors for fixed 5.0V output, eliminating external components required in adjustable variants.
It operates across an input voltage range of up to 15V and maintains regulation down to a 1.3V dropout (TO252-2 Series) at 0.8A load, while sustaining 0.003% RMS output noise (10Hz–10kHz) and 70dB ripple rejection at 120Hz with 22µF output capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0V ±1% - ensures stable logic-level supply for 5V-tolerant interfaces without external trimming. |
| Dropout Voltage | 1.3V (typ) at 0.8A - enables operation from 6.3V input in space-constrained 5V rail designs. |
| Output Current | 1.35A (typ) - supports high-current peripherals like USB hubs or FPGA I/O banks. |
| PSRR | 70dB at 120Hz - suppresses line-frequency ripple from unregulated wall adapters or DC-DC pre-regulators. |
| Quiescent Current | 6mA (max) - minimizes no-load power loss in always-on subsystems. |
| Thermal Shutdown | +160°C junction threshold with +16°C hysteresis - prevents latch-up during sustained overload or poor heatsinking. |
| Operating Temp | -20°C to +125°C - qualified for industrial and extended-temperature embedded applications. |
Pinout & Package
Package: TO252-2 (3), surface-mount, thermally enhanced DPAK variant with exposed drain pad for PCB heat dissipation (θJA = 100°C/W without heatsink; 70°C/W with heatsink).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INPUT) | Input voltage terminal | Accepts 6.3V–15V DC input; requires ≥10µF low-ESR ceramic capacitor placed near pin. |
| 2 (OUTPUT) | Regulated 5.0V output | Delivers up to 1.35A; connects directly to load and output capacitor; trace width must support peak current. |
| 3 (GND) | Ground reference and thermal pad | Common return path and primary thermal conduction path to PCB copper; must be soldered to ≥100mm² copper area. |
Key Features
| Feature | Design Value |
|---|---|
| Fixed 5.0V output | Eliminates external resistor network, reducing BOM count and layout sensitivity in cost-sensitive designs. |
| Low ESR capacitor compatible | Supports 10µF ceramic output caps (ESR <20Ω), enabling compact, high-reliability filtering without tantalum or electrolytic parts. |
| Thermal shutdown + hysteresis | +160°C trip with +16°C recovery margin prevents cycling during intermittent overloads or ambient temperature spikes. |
| ±1% output accuracy | Meets tight tolerance requirements for 5V USB peripheral power and legacy interface compliance (e.g., RS-232 transceivers). |
| 70dB PSRR at 120Hz | Enables direct use after unregulated AC/DC adapters without additional LC filtering stages. |
Applications
| USB Devices | Add-on Cards |
|---|---|
Use Scenario: Powering USB 2.0 hubs and self-powered peripherals from 7–12V wall adapters. IC Role / Device Role / Timing Role: Primary 5V LDO supplying VBUS-compatible logic and transceiver circuitry. Use Value: 1.3V dropout allows operation from 6.3V input, preserving efficiency when upstream DC-DC converter output sags under load. |
Use Scenario: Local 5V regulation on PCIe or M.2 expansion cards with shared 12V rail. IC Role / Device Role / Timing Role: Point-of-load regulator for FPGA I/O banks and interface ICs requiring clean 5V supply. Use Value: 0.003% RMS output noise ensures signal integrity for high-speed digital interfaces without added ferrite beads. |
| DVD Players | PC Motherboards |
Use Scenario: Providing regulated 5V to servo motor drivers and optical pickup control ICs. IC Role / Device Role / Timing Role: Secondary LDO decoupling noisy switching supplies for analog front-end circuits. Use Value: On-chip thermal shutdown protects against stall-induced overheating in motor driver sections during disc insertion. |
Use Scenario: Standby 5V rail generation for USB ports, SMBus controllers, and BIOS flash memory. IC Role / Device Role / Timing Role: Always-on LDO maintaining 5VSB compliance per ATX specification. Use Value: 6mA max quiescent current meets platform idle power budgets while supporting fast wake-from-suspend transitions. |
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 |
|---|---|---|---|
| MCP1700-5002E/TO | 250mA output, 6µA IQ, SOT23-5 package - lower current, ultra-low quiescent draw. | Suitable only for micro-power sensor nodes or RTC backup rails, not USB or motherboard loads. | Select when standby current dominates design priority and load ≤250mA. |
| TLV1117-50CDCYR | 800mA output, 1.2V dropout at 0.8A, SOIC-8 package - higher dropout, smaller thermal mass. | Limited to moderate-power applications; requires larger heatsinking than TO252 for same load. | Choose if board space permits SOIC footprint and thermal budget allows higher θJA. |
Compared with MCP1700-5002E/TO and TLV1117-50CDCYR, the AZ1117CD-5.0TRG1 uniquely balances 1.35A capability, 1.3V dropout, and TO252 thermal performance - making it the only option among the three qualified for sustained 5V/1A loads in industrial add-on cards without forced airflow.

Manufacturer
Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, specializing in power management, signal integrity, and protection solutions for industrial, computing, and consumer markets.

FAQ
What is the minimum input voltage required for stable 5.0V output at 1.0A?
The AZ1117CD-5.0TRG1 requires VIN ≥ VOUT + VDROP. At 1.0A, typical dropout is 1.35V (per DS36676 Rev. 5–2, p.7), so minimum input is 6.35V. Derate for worst-case conditions: use ≥6.7V to ensure regulation across temperature and process variation.
Can this device replace an LM1117-5.0 in existing designs?
Yes - AZ1117CD-5.0TRG1 shares identical pinout (TO252-2), output voltage, and functional behavior with LM1117-5.0. It improves upon LM1117 with ±1% accuracy (vs. ±2%), lower dropout (1.3V vs. 1.4V typ), and guaranteed 1.35A current limit (vs. 800mA).
Is a heatsink mandatory for 1.35A continuous operation?
No heatsink is mandatory, but thermal design is critical. With θJA = 100°C/W (no heatsink), 1.35A at 6.5V input yields ~2W dissipation, raising junction temperature by ~200°C above ambient - exceeding 125°C rating. A 100mm² copper pour is essential; heatsink recommended for >0.8A continuous loads.
What output capacitor value and type are required for stability?
A minimum 10µF low-ESR ceramic capacitor (X5R/X7R, ESR <20Ω) is required on the OUTPUT pin. Diodes recommends 22µF for optimal transient response and PSRR. Tantalum or aluminum electrolytics are not recommended due to ESR and reliability concerns.
