Product details

Overview

AZ1117CR2-5.0TRG1 from Diodes Incorporated is a fixed-output 5.0V low-dropout linear regulator in SOT89-3 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 - used for stable local regulation in USB peripherals and PC add-on cards.

For engineers reviewing the AZ1117CR2-5.0TRG1 datasheet, AZ1117CR2-5.0TRG1 pinout, AZ1117CR2-5.0TRG1 application, or AZ1117CR2-5.0TRG1 equivalent, key selection criteria include dropout voltage at full load, thermal shutdown threshold (+160°C), compatibility with low-ESR ceramic capacitors (<20Ω), minimum 10µF output capacitance, and quiescent current ≤6mA under no-load conditions.

Technical Context

The AZ1117CR2-5.0TRG1 integrates a trimmed bandgap reference and on-chip thermal shutdown circuitry, operating across -20°C to +125°C junction temperature range. Its internal current-limit protection activates at 1.35A (typ), and it maintains regulation with input-to-output differential as low as 1.3V at 0.8A load.

Designed for low-noise applications, it delivers 0.003% RMS output noise (10Hz–10kHz) relative to VOUT and achieves 70dB power supply rejection at 120Hz with 22µF output capacitor. The device requires no external components for fixed 5.0V operation and supports ceramic output capacitors with ESR <20Ω.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	5.0V ±1% - ensures stable logic-level supply for 5V-tolerant ICs without external feedback network
Dropout Voltage	1.3V (typ) at 0.8A - enables regulation from 6.3V input, critical for battery-powered or post-regulation stages
Output Current	1.35A (typ) - supports high-current digital loads like USB hubs or FPGA I/O banks
PSRR	70dB at 120Hz - suppresses ripple from upstream switching supplies feeding sensitive analog or mixed-signal circuits
Quiescent Current	≤6mA max - minimizes standby power loss in always-on subsystems
Thermal Shutdown	+160°C activation with +16°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking
RMS Output Noise	0.003% of VOUT (10Hz–10kHz) - avoids interference in audio or precision ADC reference paths

Pinout & Package

Package: SOT89-3 (TO-243AA), surface-mount, 3-terminal plastic package with exposed tab for thermal conduction. Pin 1 = INPUT, Pin 2 = OUTPUT, Pin 3 = GND.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (INPUT)	Regulator input supply connection	Accepts 6.3V–15V DC input; must be decoupled with ≥10µF low-ESR capacitor near pin
Pin 2 (OUTPUT)	Stable 5.0V regulated output	Drives load directly; requires ≥10µF ceramic capacitor (ESR <20Ω) for stability
Pin 3 (GND)	Ground reference and thermal path	Connected to PCB ground plane; exposed tab serves as primary thermal conduction path to copper

Key Features

Feature	Design Value
Fixed 5.0V output	Eliminates external resistor divider, reducing BOM count and layout area vs. adjustable LDOs
Low dropout (1.3V @ 0.8A)	Enables efficient operation from marginal input rails, e.g., 7.2V Li-ion battery after buck conversion
Thermal shutdown with hysteresis	+160°C trip and +144°C recovery prevent oscillation during thermal overload events
Ceramic capacitor compatible	Supports compact, high-reliability 10µF X5R/X7R MLCCs instead of bulkier tantalum or aluminum electrolytics
±1% output accuracy	Meets tight tolerance requirements for microcontroller core or interface I/O supply rails

Applications

IC Role / Device Role / Timing Role: Secondary regulator downstream of main system rail, delivering low-noise 5V to FPGA I/O banks or SerDes termination.

Use Value: 0.003% RMS output noise prevents jitter accumulation in high-speed serial links (e.g., PCIe Gen3).

DVD Players

PC Motherboards

Use Scenario: Supplying 5V to servo motor drivers, laser diode bias circuits, and video DACs.

IC Role / Device Role / Timing Role: Dedicated LDO for analog subsystems where switching noise would degrade video SNR or tracking accuracy.

Use Value: Thermal shutdown protects against overcurrent during mechanical jam or short-circuit in motor drive stage.

Use Scenario: Regulating 5V for legacy I/O headers, Super I/O chips, and BIOS flash memory.

IC Role / Device Role / Timing Role: Standby or auxiliary LDO maintaining 5V rail during S3/S4 sleep states with ≤6mA IQ.

Use Value: Low quiescent current extends platform battery life in notebook standby modes without sacrificing wake-up responsiveness.

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-dropout linear regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MCP1700T-5002E/MB	250mA output current, 6µA IQ, SOT23-3 package	Lower current capacity; suited for ultra-low-power microcontrollers, not 1.35A loads	Select when load current ≤250mA and standby IQ is critical; not drop-in for AZ1117CR2-5.0TRG1's 1.35A capability
LD1117S50TR	800mA output current, TO-220/TO-252 packages, ±2% VOUT accuracy	Lower current rating and looser tolerance; requires larger heatsink at full load	Choose for cost-sensitive industrial designs where 800mA suffices and ±2% is acceptable; thermal performance inferior in SOT89 footprint

Compared with MCP1700T-5002E/MB and LD1117S50TR, the AZ1117CR2-5.0TRG1 uniquely balances 1.35A delivery, ±1% accuracy, and SOT89 thermal efficiency - making it optimal for space-constrained 5V systems demanding both high current and low noise.

FAQ

What is the minimum input voltage required for stable 5.0V output at 1.0A?

The AZ1117CR2-5.0TRG1 requires a minimum input voltage of 6.3V to maintain regulation at 1.0A load, based on its typical 1.3V dropout voltage. At higher ambient temperatures or with reduced PCB copper area, the required headroom increases due to thermal derating - consult the dropout vs. junction temperature curve in DS36676 Rev. 5-2, Figure 9.

Can this regulator be used with a 4.7µF output capacitor?

No. The datasheet specifies a minimum 10µF output capacitance with ESR <20Ω for stability. Using 4.7µF risks oscillation or poor transient response, especially under load steps. A 10µF or larger X5R/X7R ceramic capacitor is mandatory per Section 4.2 of DS36676.

Does the SOT89-3 package require a thermal pad on the PCB?

Yes. The exposed tab (Pin 3/GND) is the primary thermal path. Diodes recommends soldering it to ≥100mm² of 2oz copper with ≥8 thermal vias (0.5mm diameter) to an inner ground plane, per Note 6 in Absolute Maximum Ratings. Without this, junction temperature exceeds safe limits above ~500mA.

Is the AZ1117CR2-5.0TRG1 qualified for automotive applications?

No. This part is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., AZ1117CQ series) with PPAP documentation, IATF 16949 manufacturing, and extended temperature screening. For automotive use, contact Diodes' automotive sales team to obtain qualified alternatives.
