Product details
Overview
AZ1117CR-5.0TRG1 from Diodes Incorporated is a fixed-output 5.0V low-dropout linear regulator in SOT89 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. It integrates thermal shutdown and current limiting, and is optimized for USB devices and PC motherboard power rails where transient response and low input voltage margin are critical.
For engineers reviewing the AZ1117CR-5.0TRG1 datasheet, AZ1117CR-5.0TRG1 pinout, AZ1117CR-5.0TRG1 application, or AZ1117CR-5.0TRG1 equivalent, key selection criteria include dropout voltage at full load, output noise (0.003% of VOUT), quiescent current (max 6mA), thermal resistance (170°C/W without heatsink), and compatibility with low-ESR ceramic capacitors (≤20Ω, ≥10µF).
Technical Context
The AZ1117CR-5.0TRG1 uses an internal trimmed bandgap reference to maintain ±1% output voltage accuracy across -20°C to +125°C junction temperature. Its overcurrent protection activates at 1.0–1.35A, and thermal shutdown triggers at +160°C with +16°C hysteresis.
It operates with input voltages up to 15V and requires only a 10µF ceramic output capacitor (ESR <20Ω). The device exhibits 0.003% RMS output noise (10Hz–10kHz) and maintains 70dB ripple rejection at 120Hz with 3V headroom and 300mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±1% (4.95–5.05V at 10mA, -20°C to +125°C) |
| Dropout Voltage | 1.3V typical at 0.8A load (enables operation with VIN as low as 6.3V) |
| Max Output Current | 1.35A typical (current-limited to prevent damage under overload) |
| PSRR | 70dB at 120Hz (suppresses AC line ripple in low-noise supply rails) |
| Output Noise | 0.003% of VOUT (150µV RMS at 5V output, suitable for analog-sensitive circuits) |
| Quiescent Current | 6mA maximum (low standby power for always-on subsystems) |
| Thermal Shutdown | Activates at +160°C junction temperature with +16°C hysteresis (prevents permanent failure) |
Pinout & Package
Package: SOT89 (TO-243AA), surface-mount, 3-pin, single-ended heat sink tab (pin 2). Thermal resistance θJA = 170°C/W (no heatsink), θJC = 30°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Input) | VIN | Unregulated input supply (max 15V); must be ≥6.3V for full 5.0V/1.35A operation |
| 2 (Tab) | Output / Heat Sink | Electrically connected to VOUT; primary thermal path to PCB copper pour |
| 3 (Ground) | GND | Reference return for regulation loop and current limit sensing |
Key Features
| Feature | Design Value |
|---|---|
| Low ESR capacitor support | Stable with ceramic capacitors ≥10µF and ESR ≤20Ω - eliminates need for tantalum or electrolytic |
| Bandgap-trimmed reference | ±1% output accuracy maintained over full -20°C to +125°C operating range |
| Integrated protection | Current limit (1.35A typ) and thermal shutdown (+160°C trigger) reduce external component count |
| Low-noise regulation | 0.003% RMS output noise enables use in ADC references and RF bias supplies |
| High PSRR at low frequency | 70dB rejection at 120Hz supports clean 5V rail from noisy wall adapters or switching pre-regulators |
Applications
| USB Peripheral Power | PC Motherboard Standby Rail |
|---|---|
Use Scenario: Powering USB 2.0 hubs, card readers, or HID devices from 5V bus or local 5V SMPS.

Use Value: 1.3V dropout enables regulation from 6.3V input - compatible with intermediate 7V or 6.5V pre-regulated rails common on expansion cards. |
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 |
|---|---|---|---|
| MCP1700T-5002E/MB | 250mA max output, 6µA IQ, SOT23-5 package; no current limit or thermal shutdown | Suitable only for ultra-low-power microcontroller peripherals, not high-current loads | Select when IQ <10µA is mandatory and load ≤250mA; avoid for 1A+ applications |
| LD1117S50TR | 800mA max output, TO-220/TO-252 packages, ±2% accuracy, 1.2V dropout at 0.8A | Lower current capability and wider voltage tolerance; higher thermal resistance in SOT89-equivalent packages | Choose for cost-sensitive industrial designs where 5.0V ±2% and 0.8A suffice and heatsinking is available |
Compared with MCP1700T-5002E/MB and LD1117S50TR, the AZ1117CR-5.0TRG1 uniquely balances 1.35A output, ±1% accuracy, integrated protection, and SOT89 thermal performance - making it optimal for space-constrained, medium-power USB and motherboard applications requiring reliability without external supervision.

FAQ
What is the minimum input voltage required for AZ1117CR-5.0TRG1 to regulate 5.0V at 1.35A?
The minimum input voltage is 6.3V, based on the typical 1.3V dropout voltage at 0.8A load (per datasheet DS36676 Rev. 5-2, page 7). At 1.35A, dropout increases slightly; design margin recommends VIN ≥6.5V for full-load stability across temperature and process variation.
Can AZ1117CR-5.0TRG1 be used with a 4.7µF ceramic output capacitor?
No - the datasheet specifies a minimum 10µF ceramic output capacitor with ESR ≤20Ω (page 3, Note 4). Using 4.7µF risks instability and excessive output voltage overshoot during load transients, as confirmed by the stability curves in Figure 12 (page 9).
Does AZ1117CR-5.0TRG1 require an input capacitor, and if so, what value?
Yes - a minimum 10µF aluminum or tantalum input capacitor is recommended (page 3, Typical Applications Circuit). This reduces input impedance and prevents oscillation due to trace inductance; ceramic capacitors may be used if combined with bulk capacitance to handle surge currents.
Is AZ1117CR-5.0TRG1 qualified for automotive applications per AEC-Q100?
No - the datasheet explicitly states that automotive-qualified versions require direct contact with Diodes Incorporated or its representatives (page 1). AZ1117CR-5.0TRG1 is rated for industrial temperature (-20°C to +125°C) but lacks AEC-Q100 stress testing, PPAP documentation, or IATF 16949 manufacturing certification.
