Product details
Overview
AP7366EA-20SN-7 from Diodes Incorporated is a 600mA, fixed-output 2.0V low-dropout linear regulator in U-DFN2020-6 package, featuring 60μA quiescent current, 300mV dropout at full load, and built-in thermal shutdown and current limit protection. It operates across 2.2V–6V input range and delivers stable output for FPGA I/O rails and battery-powered microcontroller subsystems.
For engineers reviewing the AP7366EA-20SN-7 datasheet, AP7366EA-20SN-7 pinout, AP7366EA-20SN-7 application, or AP7366EA-20SN-7 equivalent, key selection criteria include dropout voltage at 600mA, PSRR at 1kHz, EN pin logic thresholds, thermal resistance (θJA = 46.2°C/W), and compatibility with 1μF ceramic output capacitors.
Technical Context
The AP7366EA-20SN-7 integrates a PMOS pass element, precision 0.8V bandgap reference, and error amplifier to regulate fixed 2.0V output with ±1% accuracy over load and temperature. Its fast transient response is enabled by internal compensation optimized for 1μF ceramic output capacitance.
Enable control uses active-high EN pin with VIH ≥ 1.0V and VIL ≤ 0.3V, while protection circuitry triggers thermal shutdown at +150°C with +20°C hysteresis and limits short-circuit current to ~250mA. The device remains stable without minimum load and supports ultra-fast 150μs start-up time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.0V ±1% at 10mA; maintains regulation from -40°C to +85°C ambient |
| Max Output Current | 600mA continuous; current limit threshold 0.66–1.0A prevents damage during overload |
| Dropout Voltage | 300mV at 600mA (VIN ≥ 2.3V); enables operation with only 2.3V input for 2.0V output |
| Quiescent Current | 60μA typical; reduces standby power loss in always-on battery systems |
| PSRR | 75dB at 1kHz; suppresses ripple from noisy DC-DC pre-regulators feeding sensitive analog circuits |
| Start-up Time | 150μs to reach 90% of 2.0V; supports rapid wake-up in low-power MCU sleep modes |
| Thermal Resistance | θJA = 46.2°C/W (U-DFN2020-6); allows 425mW max power dissipation at +85°C ambient |
Pinout & Package
AP7366EA-20SN-7 is housed in a 2.0mm × 2.0mm, 0.65mm height U-DFN2020-6 package with wettable flank leads and exposed thermal pad. Pin 1 (EN) and Pin 2 (GND) are on the same side; Pin 3 (IN), Pin 4 (OUT), Pin 5 (NC), and Pin 6 (ADJ) complete the layout. The ADJ pin is internally connected to GND for fixed-output variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN | Enable input | Active-high logic control; tie to IN for always-on operation; VIH ≥ 1.0V required for turn-on |
| 2 - GND | Ground reference | Primary return path for load current and internal bias; must connect to low-impedance PCB ground plane |
| 3 - IN | Input voltage supply | Accepts 2.2V–6V; requires ≥1μF ceramic bypass capacitor placed adjacent to pin |
| 4 - OUT | Regulated output | Delivers 2.0V ±1%; stable with 1μF ceramic output capacitor; output discharge resistor ~100Ω |
| 5 - NC | No internal connection | May be left floating or tied to GND; no electrical function or performance impact |
| 6 - ADJ | Feedback reference | Internally grounded for fixed 2.0V version; not used in AP7366EA-20SN-7 configuration |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout architecture | 300mV dropout at 600mA enables use with single-cell Li-ion (2.7–4.2V) or 3.3V system rails |
| Ultra-low quiescent current | 60μA IQ ensures >1-year battery life in coin-cell powered IoT sensors drawing 10μA average load |
| Fast transient response | Load step recovery within 200μs (50mA→500mA) minimizes voltage dip on FPGA I/O banks during burst activity |
| Integrated protection | Current limit + thermal shutdown prevent latch-up or destruction during short-circuit or high-ambient conditions |
| Small-footprint packaging | U-DFN2020-6 (2.0×2.0mm) saves >60% board area vs. SOT25 while improving thermal performance (θJA 46.2 vs. 139°C/W) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-2002E/MB | 300mA output, 2.0V fixed, 1.6μA IQ, SOT-23 package | Limited to <300mA loads; unsuitable for FPGA I/O or high-current peripherals | Select when ultra-low IQ dominates over current capability and board space is constrained |
| TLS850F2BTV50 | 500mA automotive-grade LDO, AEC-Q100 qualified, 40μA IQ, 2.0V fixed | Requires automotive qualification and higher cost; lacks 600mA headroom for burst loads | Choose only for automotive production where AEC-Q100 compliance is mandatory |

FAQ
What is the maximum input voltage for AP7366EA-20SN-7?
The absolute maximum input voltage is 6.5V, but the recommended operating range is 2.2V to 6.0V. Exceeding 6.0V risks violating the 0.3V margin above VOUT specified for EN and OUT pins, and may accelerate parametric drift or reduce reliability under prolonged stress.
Can AP7366EA-20SN-7 operate without an output capacitor?
No. A minimum 1μF ceramic output capacitor is required for stability and transient response. Omitting it causes oscillation and unregulated output. The device is optimized for low-ESR ceramics; tantalum or aluminum electrolytics require larger values and introduce instability risk.
Is the ADJ pin functional in AP7366EA-20SN-7?
No. In the fixed-output AP7366EA-20SN-7 variant, the ADJ pin is internally grounded and serves no external function. It may be left floating or connected to GND without affecting regulation, per Diodes' pin description table for U-DFN2020-6 (ADJ Output) configuration.
How does thermal shutdown behave during sustained overload?
When junction temperature reaches +150°C, the output disables and remains off until temperature drops to ~+130°C due to +20°C hysteresis. Under continuous overload, this causes on/off cycling-limiting average power dissipation but requiring thermal design to avoid repeated cycling in final application.
