Product details
Overview
AZ1117R-5.0TRE1 from Diodes Incorporated is a fixed-output 5.0V, 1A low-dropout linear regulator in SOT89 package, featuring 1.15V dropout at full load, ±2% output voltage accuracy over temperature and load, and integrated thermal shutdown and current limiting. It delivers stable local regulation for microcontroller I/O rails, USB peripheral power, and FPGA auxiliary supplies where input-to-output differential is constrained.
For engineers reviewing the AZ1117R-5.0TRE1 datasheet, AZ1117R-5.0TRE1 pinout, AZ1117R-5.0TRE1 application, or AZ1117R-5.0TRE1 equivalent, key selection criteria include dropout voltage at 1A, thermal resistance in SOT89 (165°C/W), GND-referenced fixed-output topology, and compatibility with 10µF–22µF ceramic or tantalum output capacitors.
Technical Context
The AZ1117R-5.0TRE1 uses a trimmed bandgap reference and PNP pass transistor to achieve 5.0V ±2% output tolerance across –40°C to +125°C junction temperature. Its internal current limit 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 the device operates with input voltages up to 15V (recommended) or 20V (absolute max). Ripple rejection reaches 75dB at 120Hz with 22µF tantalum output capacitance and 3V headroom.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0V ±2% (10mA–1A load, –40°C to +125°C); ensures logic-level compliance for 5V TTL/CMOS systems. |
| Dropout Voltage | 1.15V at 1A (ΔVOUT = 1%); enables operation from 6.5V input in space-constrained 5V rail designs. |
| Output Current | 1A continuous; supports single-chip MCU, Ethernet PHY, or dual USB port power delivery. |
| Thermal Shutdown | Triggers at +150°C junction temperature with +25°C hysteresis; prevents permanent damage during sustained overload. |
| Line Regulation | ≤10mV over 1.5V–10V input differential; maintains stable output despite upstream DC/DC ripple or battery sag. |
| Ripple Rejection | 75dB at 120Hz (22µF tantalum, 3V headroom); suppresses switching noise from adjacent buck converters. |
| Quiescent Current | 5–10mA; minimizes no-load power loss in always-on subsystems like RTC or wake-up circuitry. |
Pinout & Package
Package: SOT89 - 3-pin surface-mount plastic package with exposed thermal pad (pin 2 is INPUT, pin 3 is GND, pin 1 is OUTPUT).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTPUT) | Regulated 5.0V output terminal | Connects directly to load; requires ≥10µF output capacitor for stability and transient response. |
| 2 (INPUT) | Unregulated input supply connection | Accepts 6.5–15V DC; must be decoupled with ≥1µF ceramic capacitor near pin. |
| 3 (GND) | Ground reference and thermal path | Serves as return for all internal circuits and primary heat dissipation path to PCB copper. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout voltage | 1.15V at 1A enables use with 6.5V input in legacy 5V systems where headroom is limited. |
| Factory-trimmed output accuracy | ±2% over full temperature and load range eliminates need for external calibration in cost-sensitive designs. |
| Integrated thermal shutdown | +150°C trip with +25°C hysteresis provides autonomous recovery after fault clearance without system intervention. |
| Current limiting | 1.25–1.35A hard limit protects both IC and upstream source during output short or overload. |
| Lead-free & RoHS-compliant | Fully compliant with EU RoHS 2015/863/EU; suitable for consumer, industrial, and telecom end equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-5002E/TO | 250mA output, 600mV dropout at 250mA, SOT23-3 package | Lower current capacity; suited for ultra-low-power sensors or MCU cores, not 1A loads | Select only when load current ≤250mA and board space is critical. |
| LD1117S50TR | 1A output, 1.1V dropout at 1A, TO220-3/SOT223 options, ±2% accuracy | Higher thermal resistance in SOT223 (120°C/W vs. SOT89's 165°C/W); better heatsinking in TO220 | Prefer for higher ambient temperatures (>60°C) or when TO220 mounting is acceptable. |
Compared with MCP1700-5002E/TO, AZ1117R-5.0TRE1 supports 4× higher load current and matches LD1117S50TR in output accuracy but offers lower thermal resistance in TO252 variants-though its SOT89 variant trades off some thermal performance for compact footprint.

FAQ
What is the minimum input voltage required for AZ1117R-5.0TRE1 to maintain regulation?
The minimum input voltage is 6.5V under recommended operating conditions (10mA–1A load, –40°C to +125°C), derived from the 5.0V output plus 1.15V typical dropout at 1A. At lighter loads (e.g., 10mA), input can drop to 6.15V while maintaining regulation, but design margin should retain ≥6.5V to ensure stability across temperature and line variation.
Can AZ1117R-5.0TRE1 be used with ceramic output capacitors?
Yes-ceramic capacitors ≥10µF are compatible and recommended for improved transient response and reduced board area. The device is stable with ESR as low as 10mΩ; no series resistor is needed. However, ensure capacitor voltage rating exceeds 6.3V to accommodate input transients up to 20V absolute maximum.
Does AZ1117R-5.0TRE1 require an input bypass capacitor?
Yes-a minimum 1µF X5R/X7R ceramic capacitor placed within 5mm of the INPUT and GND pins is required to suppress high-frequency noise and prevent oscillation. Larger values (e.g., 4.7–10µF) improve immunity to upstream switching noise and reduce input ripple propagation.
How does thermal performance differ between SOT89 and SOT223 packages for the AZ1117 series?
SOT89 has θJA = 165°C/W (no heatsink), while SOT223 is 120°C/W-making SOT223 thermally superior for same PCB layout. However, SOT89's smaller footprint and lower profile suit height-constrained applications; both require adequate copper pour on GND pin for effective heat spreading.
