Product details
Overview
AZ1117IH-5.0TRG1 from Diodes Incorporated is a fixed-output 5.0 V, 1.35 A low-dropout linear regulator in SOT223 package, optimized for industrial temperature range (−40°C to +125°C), with ±1% output voltage accuracy, 1.3 V typical dropout at 0.8 A, and integrated thermal shutdown. It powers USB peripherals and PC motherboard auxiliary rails where stable low-noise 5 V supply and transient response are critical.
For engineers reviewing the AZ1117IH-5.0TRG1 datasheet, AZ1117IH-5.0TRG1 pinout, AZ1117IH-5.0TRG1 application, or AZ1117IH-5.0TRG1 equivalent, key selection criteria include dropout voltage at full load, PSRR at 120 Hz, RMS output noise (0.003% of VOUT), quiescent current (≤6 mA), and compatibility with low-ESR ceramic capacitors (ESR < 20 Ω).
Technical Context
The AZ1117IH-5.0TRG1 employs a trimmed bandgap reference and internal current-limiting circuitry to maintain ±1% output regulation across −40°C to +125°C junction temperature. Its thermal shutdown activates at +160°C with +16°C hysteresis, ensuring safe operation under overload or high ambient conditions.
Designed for low-voltage systems, it achieves 70 dB PSRR at 120 Hz with 22 µF output capacitance and supports input voltages up to 15 V. The device requires ≥10 µF output capacitor and operates stably with ceramic capacitors having ESR below 20 Ω.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±1% (guaranteed over −40°C to +125°C; ensures stable logic-level rail for USB/PCIe add-on cards) |
| Dropout Voltage | 1.3 V typ @ 0.8 A (enables operation with VIN as low as 6.3 V while sustaining full load) |
| PSRR | 70 dB @ 120 Hz, 300 mA (suppresses ripple from noisy DC-DC pre-regulators feeding sensitive analog circuits) |
| RMS Output Noise | 0.003% of VOUT (22 µV RMS for 5 V output; suitable for low-noise analog sensor interfaces) |
| Quiescent Current | 6 mA max (minimizes standby power loss in always-on embedded control modules) |
| Thermal Shutdown | +160°C activation with +16°C hysteresis (prevents permanent damage during sustained overload or poor heatsinking) |
| Operating Junction Temp | −40°C to +125°C (supports industrial automation, automotive body electronics, and outdoor equipment) |
Pinout & Package
Package: SOT223 - thermally enhanced 3-pin surface-mount package with exposed thermal pad (pin 2 is tab-connected to GND for optimal heat dissipation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INPUT) | Regulator Input | Accepts unregulated DC input up to 15 V; requires ≥10 µF low-ESR ceramic capacitor placed near pin |
| 2 (OUTPUT) | Regulated Output | Delivers stable 5.0 V; connects directly to load and output capacitor; pin 2 tab must be soldered to PCB ground plane |
| 3 (GND) | Ground Reference | Common return path for internal bandgap, error amplifier, and thermal protection; ties to system ground and output capacitor negative terminal |
Key Features
| Feature | Design Value |
|---|---|
| Current Limit | 1.35 A typical - prevents catastrophic failure during short-circuit or inrush events without external foldback circuitry |
| Low-ESR Capacitor Support | Stable with ceramic caps ≤20 Ω ESR - eliminates need for costly tantalum or aluminum electrolytic output capacitors |
| Industrial Temp Range | −40°C to +125°C operation - qualified for use in factory-floor PLCs, motor drives, and telecom infrastructure |
| Output Voltage Accuracy | ±1% over full temp/load range - reduces need for post-regulation trimming in precision 5 V power domains |
| Lead-Free & Green | RoHS 3 compliant, halogen- and antimony-free - meets global environmental compliance requirements for industrial OEMs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC29302WU-5.0 | Higher dropout (1.5 V @ 3 A), TO263-5 package, 1.5 A rating | Better suited for higher-current loads but requires larger board area and heatsinking | Select when >1.35 A continuous load or higher thermal margin is required |
| TLV1117-50IDCYR | Lower IQ (10 mA max), SOT223, ±2% accuracy, 1.2 V dropout @ 0.8 A | Optimized for ultra-low-power battery-backed systems, not industrial temp range | Select only for cost-sensitive consumer designs operating within 0°C to +70°C |
Compared with MIC29302WU-5.0 and TLV1117-50IDCYR, the AZ1117IH-5.0TRG1 uniquely balances industrial temperature support, ±1% accuracy, and SOT223 thermal performance-making it optimal for space-constrained industrial PCBs requiring guaranteed 5 V stability across harsh environments.

FAQ
What is the minimum output capacitance required for stable operation?
The AZ1117IH-5.0TRG1 requires a minimum 10 µF ceramic output capacitor with ESR less than 20 Ω. This value ensures phase margin stability across all load and temperature conditions per the datasheet's recommended operating conditions and typical application circuits.
Can this part replace the standard AZ1117-5.0 in existing designs?
Yes-the AZ1117IH-5.0TRG1 is a direct drop-in replacement for the commercial-grade AZ1117-5.0, offering identical pinout, electrical specs, and SOT223 footprint, plus extended −40°C to +125°C operation and tighter ±1% output tolerance.
Does it require an input capacitor?
An input capacitor is strongly recommended: ≥10 µF low-ESR ceramic placed within 5 mm of the INPUT pin. While not strictly mandatory for stability, it reduces input impedance, suppresses supply-line transients, and prevents oscillation during fast load steps.
How does thermal shutdown behave under sustained overload?
Thermal shutdown activates at +160°C junction temperature and holds the output off until junction temperature drops by +16°C hysteresis (to ~+144°C). During shutdown, quiescent current remains ≤6 mA, and the device automatically recovers without manual reset once cooled.
