Product details
Overview
AP7365-20EG-13 from Diodes Incorporated is a fixed-output 2.0V, 600mA low-dropout linear regulator with enable control, 35μA quiescent current, 300mV dropout at full load, and stable operation with 1μF ceramic output capacitance. It serves as a core power supply for FPGA I/O rails and portable DSP subsystems requiring fast transient response and battery-efficient operation.
For engineers reviewing the AP7365-20EG-13 datasheet, AP7365-20EG-13 pinout, AP7365-20EG-13 application, or AP7365-20EG-13 equivalent, key selection criteria include its 2.0V fixed output accuracy (±2%), thermal shutdown threshold (+145°C), EN logic-high activation (VIH ≥ 1.4V), PSRR of 65dB at 1kHz, and compatibility with SOT223-E package thermal performance (θJA = 142°C/W).
Technical Context
The AP7365-20EG-13 integrates a PMOS pass element, precision 0.8V bandgap reference, and internal error amplifier to regulate output voltage with ±2% accuracy across –40°C to +85°C ambient. Its current-limit circuit triggers at 0.8–1.4A and short-circuit protection clamps output to 240mA under fault conditions.
Thermal shutdown activates at +145°C junction temperature with +15°C hysteresis, enabling self-recovery at +130°C. The device achieves 200μs start-up time and maintains stability with low-ESR 1μF ceramic capacitors on both input and output, eliminating minimum load requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.0V ±2% over –40°C to +85°C; enables direct powering of 2.0V I/O domains without external resistors. |
| Max Output Current | 600mA continuous; supports FPGA I/O banks and mid-power microcontroller peripherals without derating at TA ≤ 60°C. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥ 2.5V); for 2.0V output, typical dropout is 370mV - allows operation from 2.37V input in battery-depleted states. |
| Quiescent Current | 35μA typical at zero load; extends runtime in always-on sensor nodes and standby modes of portable electronics. |
| PSRR | 65dB at 1kHz; suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Enable Threshold | VIH = 1.4V min, VIL = 0.4V max; compatible with 1.8V/3.3V GPIO without level-shifting. |
| Thermal Shutdown | Activates at TJ = +145°C with +15°C hysteresis; prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
AP7365-20EG-13 is packaged in SOT223-E (E Package), featuring an exposed thermal pad on the underside for enhanced heat dissipation. The package has three signal terminals and one thermal tab (OUT), with θJA = 142°C/W on standard FR-4 board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 3) | Input voltage supply | Accepts 2.0V–6.0V; requires ≥1μF ceramic bypass capacitor placed adjacent to pin to suppress high-frequency noise and ensure stability. |
| GND (Pin 1) | Ground reference | Low-impedance return path for all internal circuits; must connect directly to power plane under thermal pad for optimal thermal performance. |
| OUT (Pin 2) | Regulated output | Delivers fixed 2.0V; connects to thermal tab - PCB copper area under tab must be solid and unbroken to achieve rated θJA. |
| EN (Not present) | Enable control | Not implemented in SOT223-E fixed-output variant; regulator is permanently enabled - IN-to-OUT path is always active when powered. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 35μA typical enables >1-year battery life in coin-cell-powered IoT sensors operating at 10μA average load. |
| Fast transient response | Stabilizes within <50μs during 10mA→600mA load steps - critical for GSM/TDMA baseband power integrity. |
| Single-capacitor stability | Operates stably with only 1μF ceramic output capacitor (ESR >15mΩ), reducing BOM count and PCB area vs. legacy LDOs. |
| Integrated protection | Combines current limit (0.8–1.4A), short-circuit clamp (240mA), and thermal shutdown (+145°C) - eliminates need for external fault management circuitry. |
| Wide input range | 2.0V–6.0V input supports single-cell Li-ion (2.7–4.2V), two-cell alkaline (2.0–3.2V), and 3.3V/5V system rails. |
Applications
| FPGA I/O Power | DSP Core Supply |
|---|---|
|
Use Scenario: Powering configurable I/O banks in Xilinx Artix-7 or Intel MAX 10 FPGAs where voltage margin is tight and load transients exceed 300mA. IC Role / Device Role / Timing Role: Primary 2.0V LDO delivering clean, low-noise bias to I/O buffers and transceivers during configuration and high-speed data transfer. Use Value: 65dB PSRR at 1kHz rejects noise from adjacent switching regulators; 200μs start-up enables rapid reconfiguration without power sequencing delays. |
Use Scenario: Supplying TMS320C6748 DSP core logic in industrial audio analyzers requiring stable 2.0V under dynamic FFT processing loads. IC Role / Device Role / Timing Role: Low-dropout post-regulator stepping down from 3.3V intermediate rail to meet core voltage tolerance (±2%) across temperature. Use Value: 300mV dropout ensures regulation down to 2.3V input - extends usable battery range by 12% compared to 400mV-dropout alternatives. |
| Portable Medical Sensor Hub | Smart Meter RF Subsystem |
|
Use Scenario: Powering ECG front-end ASIC and BLE radio in wearable patch monitors with coin-cell (CR2032) primary source. IC Role / Device Role / Timing Role: Always-on 2.0V supply maintaining sub-50μA total system quiescent current during sleep mode. Use Value: 35μA IQ minimizes standby drain - enables 24-month shelf life; thermal shutdown prevents overheating during accidental short-circuit events. |
Use Scenario: Providing regulated 2.0V to sub-GHz RF transceivers (e.g., TI CC1312) in ANSI C12.19-compliant smart meters exposed to outdoor temperature extremes. IC Role / Device Role / Timing Role: Industrial-grade LDO ensuring uninterrupted RF link operation across –40°C to +85°C ambient. Use Value: Guaranteed ±2% output accuracy and +145°C thermal cutoff maintain RF PA bias stability and prevent packet loss during summer peak-load conditions. |
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 |
|---|---|---|---|
| AP7361-20W5-7 | SOT25 package (θJA = 169°C/W), no thermal pad; 35μA IQ, same 2.0V/600mA spec but lower thermal capability. | Suitable for space-constrained PCBs where thermal pad routing is impractical; limited to ≤300mA continuous in 60°C ambient. | Select when footprint size is prioritized over thermal headroom and output current demand stays below 400mA. |
| MCP1700T-2002E/TT | 250mA max output, 1.6μA IQ, SOT23-5; lacks current limit and thermal shutdown; ±2% accuracy only at 25°C. | Only viable for ultra-low-power sensor nodes (<100mA), not for FPGA/DSP loads; requires external protection circuitry. | Choose only for battery-life-critical, low-current applications where cost per unit is paramount and fault protection is handled elsewhere. |
Compared with AP7365-20EG-13, AP7361-20W5-7 trades thermal robustness for smaller footprint, while MCP1700T-2002E/TT sacrifices current capability and integrated protection to achieve nanoamp quiescent current - neither matches the 600mA/thermal shutdown/2.0V accuracy combination required for industrial FPGA or DSP power rails.

FAQ
Is AP7365-20EG-13 pin-compatible with other AP7365 variants?
No - AP7365-20EG-13 uses the SOT223-E package with three pins (IN, GND, OUT) and no EN or ADJ terminals. Adjustable versions (e.g., AP7365-ADJWG-7) use SOT25 or U-DFN2020-6 packages with five or six pins including EN and ADJ. Pin mapping and thermal pad configuration differ fundamentally across packages.
What is the minimum input voltage required for 2.0V output at 600mA?
The minimum input voltage is 2.37V, calculated from the typical dropout voltage of 370mV at 600mA for VOUT = 2.0V (per Electrical Characteristics table, Note 5). At worst-case 600mV dropout, VIN must be ≥2.6V to sustain regulation under full load and temperature extremes.
Can AP7365-20EG-13 operate without an output capacitor?
No - the datasheet explicitly requires a minimum 1μF ceramic output capacitor (ESR >15mΩ) for stability. Omitting it causes oscillation and voltage overshoot during load transients; the device is not unity-gain stable without this capacitor, unlike some older LDO architectures.
Does AP7365-20EG-13 support AEC-Q100 qualification?
AP7365-20EG-13 itself is not AEC-Q100 qualified; however, Diodes Incorporated offers automotive-grade versions (e.g., AP7365-20EG-13Q) manufactured in IATF 16949-certified facilities with PPAP documentation and extended temperature screening - contact Diodes sales for qualified part numbers and change control support.
