Product details
Overview
AP7366EA-20W5-7 from Diodes Incorporated is a fixed-output 2.0V, 600mA low-dropout linear regulator in SOT25 package with enable control, 60μA quiescent current, 300mV dropout at full load, and ±1% output voltage accuracy. It delivers stable power to FPGA I/O rails and DSP cores in battery-powered notebooks and servers where low standby power and fast transient response are critical.
For engineers reviewing the AP7366EA-20W5-7 datasheet, AP7366EA-20W5-7 pinout, AP7366EA-20W5-7 application, or AP7366EA-20W5-7 equivalent, this page provides verified technical context, validated pin functions, confirmed thermal and PSRR performance, and real-world design implications for portable and embedded power systems.
Technical Context
The AP7366EA-20W5-7 integrates a PMOS pass element, precision 0.8V bandgap reference, and error amplifier optimized for stability with 1μF ceramic output capacitors. Its EN pin enables direct logic-level control (VIH = 1.0V, VIL = 0.3V) without external pull-ups.
Thermal shutdown activates at +150°C with +20°C hysteresis, and current limiting clamps output to 660–1000mA depending on input conditions. PSRR reaches 75dB at 1kHz, supporting noise-sensitive analog and digital loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.0V ±1% over -40°C to +85°C ambient - ensures reliable core/I/O rail compliance without external feedback components. |
| Max Output Current | 600mA continuous - supports single-rail powering of mid-power FPGA I/O banks or microcontroller peripherals. |
| Quiescent Current | 60μA typical - extends battery runtime in always-on sensor nodes and portable devices during deep-sleep modes. |
| Dropout Voltage | 300mV at 600mA - enables operation down to VIN = 2.3V, compatible with single-cell Li-ion (2.7–4.2V) and 3.3V system rails. |
| PSRR | 75dB at 1kHz - suppresses switching noise from adjacent DC/DC converters feeding mixed-signal SoCs. |
| Start-up Time | 150μs - allows rapid wake-up from low-power states without compromising system responsiveness. |
| Thermal Shutdown | Triggers at +150°C junction temperature with +20°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
SOT25 package (3.0mm × 2.8mm × 1.3mm), thermally enhanced with exposed pad (not electrically connected), RoHS-compliant matte tin plating, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input voltage supply | Accepts 2.2–6.0V; requires ≥1μF MLCC bypass close to pin to suppress high-frequency noise and ensure stability. |
| 2 - GND | Power ground reference | Low-impedance return path; must be connected to solid ground plane to minimize voltage bounce during load transients. |
| 3 - EN | Enable control input | Active-high logic interface (VIH ≥ 1.0V); internal 3MΩ pull-down allows default-off operation when left floating. |
| 4 - NC | No internal connection | Unbonded pad; must remain unconnected and unstubbed to avoid parasitic coupling or solder bridging. |
| 5 - OUT | Regulated output | Delivers 2.0V ±1% at up to 600mA; requires ≥1μF ceramic capacitor directly between OUT and GND for transient stability. |
Key Features
| Feature | Design Value |
|---|---|
| Low-IQ operation | 60μA quiescent current enables >1-year battery life in coin-cell–powered IoT sensors with 10s-of-μA average load. |
| Fast transient response | Load step recovery within 200μs (50mA ↔ 500mA) minimizes undershoot/overshoot on FPGA I/O rails during burst-mode processing. |
| Stability with minimal capacitance | Guaranteed stable with 1μF ceramic output capacitor - reduces BOM count and PCB area vs. legacy LDOs requiring ≥10μF. |
| Integrated protection | Current limit (≥660mA), short-circuit clamp (~250mA), and thermal shutdown prevent field failures under fault conditions without external circuitry. |
| High PSRR at audio frequencies | 75dB rejection at 1kHz enables clean power delivery to ADC reference supplies and RF front-end bias rails. |

| Portable Notebook I/O Power | FPGA Core Voltage Regulation |

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 max output, 2.0V fixed, 1.6μA IQ, 600mV dropout at 250mA | Lower current capability; suited only for sub-300mA logic rails, not FPGA I/O or sensor hubs with burst loads | Select when ultra-low IQ dominates over output current and transient performance. |
| TLS820B2L1ETV50 | Automotive AEC-Q100 qualified, 2.0V fixed, 250mA, integrated watchdog and reset | Designed for automotive body electronics; lacks 600mA drive and fast transient response needed for computing loads | Select only for automotive OEM designs requiring PPAP and functional safety features. |

FAQ
What is the minimum input voltage required for AP7366EA-20W5-7 to regulate 2.0V output at 600mA?
The minimum input voltage is 2.3V, derived from the 300mV dropout specification at 600mA load. At VIN = 2.3V, the device maintains regulation at VOUT = 2.0V. Operation below 2.2V violates the absolute maximum rating and risks unregulated output or shutdown.
Can AP7366EA-20W5-7 operate without an output capacitor?
No. A minimum 1μF ceramic capacitor is mandatory between OUT and GND for stability and transient response. Omitting it causes oscillation, excessive output ripple, and potential thermal shutdown due to instability-induced power dissipation.
Is the EN pin internally pulled down, and what happens if left unconnected?
Yes-the EN pin has a 3MΩ internal pull-down resistor. If left unconnected, the device remains disabled. To enable permanently, tie EN directly to IN; do not use weak pull-ups, as VIH threshold is only 1.0V and noise margins are narrow.
How does thermal shutdown behave under sustained overload at +70°C ambient?
At +70°C ambient and 600mA load with VIN = 4.0V, power dissipation is ~1.2W. With θJA = 139°C/W, junction temperature rises ~167°C above ambient, triggering shutdown at ~237°C-well above the +150°C threshold. The device cycles on/off until load or ambient is reduced.
