Product details
Overview
AP7366EA-30W5-7 from Diodes Incorporated is a 600mA fixed-output (3.0V) low-dropout linear regulator in SOT25 package, featuring 60μA quiescent current, 300mV dropout at full load, and integrated enable control. It delivers stable power to FPGA I/O rails, notebook CPU cores, and battery-powered IoT sensors where low standby power and fast transient response are critical.
For engineers reviewing the AP7366EA-30W5-7 datasheet, AP7366EA-30W5-7 pinout, AP7366EA-30W5-7 application, or AP7366EA-30W5-7 equivalent, this page provides verified electrical parameters, thermal performance data, EN-controlled startup timing, and validated SOT25 footprint compatibility for immediate PCB integration.
Technical Context
The AP7366EA-30W5-7 integrates a PMOS pass element with bandgap reference, error amplifier, and thermal shutdown circuitry. Its 0.8V internal reference enables precise 3.0V output via factory-trimmed resistor network, eliminating external feedback components.
It operates across 2.2V–6V input range with 75dB PSRR at 1kHz and achieves 150μs start-up time from EN assertion to regulated 3.0V output under 30Ω load. Built-in current limit (≥660mA typ.) and thermal shutdown (150°C trigger, 20°C hysteresis) ensure fault resilience without external protection circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±1% accuracy at 10mA load ensures reliable logic-level compliance for 3.3V-tolerant I/O domains. |
| Max Output Current | 600mA continuous delivery supports mid-power digital loads like ARM Cortex-M7 peripherals or DDR3L termination rails. |
| Quiescent Current | 60μA typical enables >1-year battery life in always-on sensor nodes powered by CR2032 cells. |
| Dropout Voltage | 300mV at 600mA allows operation from single-cell Li-ion (3.0V min.) down to 3.3V output with 0.3V headroom. |
| PSRR | 75dB at 1kHz suppresses switching noise from adjacent DC/DC converters, preserving ADC reference stability. |
| Start-up Time | 150μs enables rapid wake-from-sleep sequencing in portable devices without voltage droop-induced resets. |
| Thermal Shutdown | 150°C junction threshold with 20°C hysteresis prevents permanent damage during sustained overload or poor heatsinking. |
Pinout & Package
SOT25 package (3.0mm × 2.8mm × 1.3mm) with exposed pad for thermal enhancement; JEDEC-standard footprint compatible with automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input voltage supply | Accepts 2.2–6V; requires ≥1μF ceramic bypass capacitor placed adjacent to pin for EMI suppression and stability. |
| 2 - GND | Power ground reference | Low-impedance return path; must connect directly to PCB ground plane beneath device for thermal and noise control. |
| 3 - EN | Enable control input | Active-high logic interface (VIH ≥1.0V); ties to IN for always-on operation or drives from microcontroller GPIO for dynamic power gating. |
| 4 - NC | No internal connection | Floating or grounded-no electrical impact; omitted in layout to reduce routing complexity. |
| 5 - OUT | Regulated 3.0V output | Delivers up to 600mA; requires ≥1μF ceramic capacitor at pin for load transient immunity and stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 60μA quiescent current enables >10-year shelf life in energy-harvesting applications with intermittent duty cycles. |
| Fast transient response | Sub-200μs recovery from 100mA→500mA load steps minimizes voltage dip on sensitive RF front-end supplies. |
| Low-ESR capacitor support | Stable with 1μF ceramic output capacitor eliminates need for costly tantalum or polymer alternatives. |
| Integrated protection | Current limit (≥660mA), short-circuit clamp (~250mA), and thermal shutdown prevent field failures without external circuitry. |
| Wide input range | 2.2–6V operation supports direct connection to USB VBUS, Li-ion batteries, or multi-rail intermediate supplies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-3002E/TO | 300mA max output, 1.6μA IQ, no EN pin, TO-92 package | Limited to ultra-low-power microcontrollers; lacks enable control for dynamic power management | Select when IQ <2μA is mandatory and load current never exceeds 300mA. |
| TLS850B0TE/V1 | 500mA, 35μA IQ, AEC-Q100 qualified, integrated watchdog | Automotive-grade with fail-safe features; larger SOIC-8 footprint and higher cost | Select only for automotive ECUs requiring PPAP documentation and extended temperature validation. |
Compared with MCP1700-3002E/TO and TLS850B0TE/V1, AP7366EA-30W5-7 uniquely balances 600mA drive capability, 60μA IQ, and EN control in a compact SOT25 package-making it optimal for consumer and industrial portable electronics where size, efficiency, and controllability intersect.

FAQ
What is the minimum input voltage required for AP7366EA-30W5-7 to maintain 3.0V output at 600mA?
The minimum input voltage is 3.3V, calculated from the 300mV dropout specification at 600mA load. Below 3.3V, output regulation degrades; operation at 2.2V input is only valid for lighter loads where dropout remains within spec.
Can AP7366EA-30W5-7 operate without an output capacitor?
No. A minimum 1μF ceramic capacitor is mandatory at the OUT pin for stability and transient response. Omitting it causes oscillation and potential device failure under load changes, as confirmed by stability testing in the datasheet's Application Information section.
Is the EN pin internally pulled down when not driven?
No. The EN pin has no internal pull-down; its 3MΩ pull-down resistor is external. If left floating, the device may power up unpredictably due to noise coupling. Tie EN to IN for always-on operation or use a dedicated GPIO with defined logic levels.
How does thermal resistance differ between SOT25 and U-DFN2020-6 packages?
SOT25 has θJA = 139°C/W, while U-DFN2020-6 achieves 46.2°C/W due to its bottom-exposed thermal pad. For 600mA at 3.3V input, SOT25 junction temperature rises ~25°C above ambient, whereas U-DFN2020-6 rises only ~8°C-enabling higher power density in thermally constrained layouts.
