Product details
Overview
AZ1117H-5.0TRE1 from Diodes Incorporated is a fixed-output 5.0V, 1A low-dropout linear regulator in SOT223 package, delivering ±1% output voltage accuracy at 25°C, 1.15V dropout at full load, and integrated thermal shutdown and current limiting. It serves as a primary post-regulation supply for FPGA I/O banks, microcontroller core logic, and USB peripheral power rails in space-constrained industrial control modules.
For engineers reviewing the AZ1117H-5.0TRE1 datasheet, AZ1117H-5.0TRE1 pinout, AZ1117H-5.0TRE1 application, or AZ1117H-5.0TRE1 equivalent, key selection criteria include dropout voltage at 1A, thermal resistance (θJA = 120°C/W), GND-referenced fixed-output topology, and RoHS-compliant lead-free SOT223 packaging for reflow-compatible assembly.
Technical Context
The AZ1117H-5.0TRE1 uses an internal trimmed bandgap reference and PNP pass transistor to maintain stable 5.0V output across input voltages from 6.5V to 12V and junction temperatures from –40°C to +125°C. Its current-limit threshold is factory-trimmed to 1.25–1.35A, ensuring predictable short-circuit behavior without external sensing.
Thermal protection activates at +150°C junction temperature with +25°C hysteresis, and ripple rejection reaches 75dB at 120Hz with 22µF tantalum output capacitance. The device operates without minimum load requirement-unlike adjustable variants-and draws only 5–10mA quiescent current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0V ±1% (10mA–1A load, 25°C); ensures compatibility with 5V TTL/CMOS logic and USB 2.0 VBUS-tolerant interfaces. |
| Dropout Voltage | 1.15V at 1A (ΔVOUT = 1%); enables regulation from 6.5V input, supporting 7V wall adapters or 12V rail derating. |
| Current Limit | 1.25–1.35A (VIN–VOUT = 2V); provides controlled short-circuit current, eliminating need for external fuse or polyfuse. |
| Thermal Shutdown | Activates at +150°C junction temperature with +25°C hysteresis; prevents permanent damage during sustained overload or poor heatsinking. |
| Quiescent Current | 5–10mA (VIN = VOUT + 1.25V); minimizes no-load power loss in always-on subsystems like real-time clocks or wake-on-LAN circuitry. |
| Ripple Rejection | 75dB at 120Hz (COUT = 22µF tantalum); suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Operating Temp | –40°C to +125°C junction range; qualified for industrial motor drives, automotive body controllers, and outdoor telecom equipment. |
Pinout & Package
SOT223 package: 4-pin thermally enhanced plastic surface-mount outline with exposed thermal pad (pin 4 internally connected to GND). Pin 1 = OUTPUT, Pin 2 = INPUT, Pin 3 = GND. Pin 4 = GND (thermal tab).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (OUTPUT) | Regulated 5.0V output node | Connects directly to load; requires ≥10µF ceramic or tantalum output capacitor for stability and transient response. |
| Pin 2 (INPUT) | Unregulated input supply input | Accepts 6.5–12V DC; must be filtered prior to entry to limit ripple-induced PSRR degradation. |
| Pin 3 (GND) | Reference and return path | Low-impedance ground connection essential for output accuracy and thermal performance; ties to PCB ground plane under thermal pad. |
| Pin 4 (GND / Thermal Pad) | Thermal and electrical ground | Internally bonded to die substrate; must be soldered to ≥1cm² copper pour for θJA = 120°C/W rating. |
Key Features
| Feature | Design Value |
|---|---|
| Fixed 5.0V output | Eliminates external resistor divider, reducing BOM count and layout area versus adjustable LDOs. |
| 1.15V dropout @ 1A | Enables higher efficiency than legacy 7805 regulators in 7V-input systems, cutting power dissipation by >30%. |
| ±1% output accuracy | Meets tight tolerance requirements of ADC references, sensor signal chains, and precision analog front-ends. |
| Integrated thermal shutdown | Self-protecting operation removes need for external thermal monitoring ICs or discrete NTC circuits. |
| Lead-free & RoHS compliant | Meets EU Directive 2015/863/EU (RoHS 3); compatible with Pb-free reflow profiles up to 260°C peak. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC29302WU-5.0 | Higher dropout (0.4V typical @ 3A), TO263-3 package, 0.5% initial accuracy | Supports 3A load but requires larger footprint and heatsink; better for high-current 5V rails | Select when >1A continuous load or tighter initial accuracy is required; not drop-in due to pinout and thermal design differences |
| TLV1117-50CDCYR | Lower IQ (4mA typ), SOT223-3, ±2% accuracy, 1.2V dropout @ 1A | Optimized for ultra-low-power battery-backed systems; less robust thermal shutdown hysteresis (+15°C) | Prefer for portable devices with intermittent 5V loads; avoid in thermally demanding industrial enclosures |
Compared with MIC29302WU-5.0 and TLV1117-50CDCYR, the AZ1117H-5.0TRE1 balances cost, thermal performance in SOT223, and proven reliability in fixed 5V industrial power rails-making it optimal for volume production where 1A capability and 120°C/W θJA are design constraints.

FAQ
What is the maximum input voltage for AZ1117H-5.0TRE1?
The absolute maximum input voltage is 20V, but the recommended operating maximum is 12V per the datasheet's "Recommended Operating Conditions" table. Exceeding 12V reduces safe operating area margin, increases power dissipation, and risks thermal shutdown during full-load operation at elevated ambient temperatures.
Does AZ1117H-5.0TRE1 require an output capacitor?
Yes-a minimum 10µF output capacitor is mandatory for stability. The datasheet specifies 10µF ceramic or 22µF tantalum; using less capacitance or incorrect ESR may cause oscillation or poor transient response. The capacitor must be placed within 5mm of the OUTPUT and GND pins.
Can AZ1117H-5.0TRE1 be used in parallel for higher current?
No-parallel operation is not supported. The AZ1117H-5.0TRE1 lacks current-sharing features such as remote sensing or master-slave enable. Uneven thermal gradients and output voltage mismatches (±1%) would cause one device to hog current, leading to premature thermal shutdown.
Is there a newer replacement recommended by Diodes Incorporated?
Yes-the datasheet explicitly states "NOT RECOMMENDED FOR NEW DESIGN USE AZ1117C or AZ1117I". The AZ1117C series offers improved PSRR (80dB), lower dropout (1.1V typ), and enhanced thermal performance in identical SOT223 packaging, with full pin-to-pin compatibility and same 5.0V fixed output.
