Product details
Overview
AP7366EA-25SN-7 from Diodes Incorporated is a 600mA fixed-output (2.5V) low-dropout linear regulator in U-DFN2020-6 package, featuring 60μA quiescent current, 300mV dropout at full load, and 75dB PSRR at 1kHz. It integrates enable control, thermal shutdown, and current limiting for battery-powered portable electronics requiring stable low-voltage rail generation.
For engineers reviewing the AP7366EA-25SN-7 datasheet, AP7366EA-25SN-7 pinout, AP7366EA-25SN-7 application, or AP7366EA-25SN-7 equivalent, key selection criteria include dropout voltage at 600mA, EN logic thresholds, thermal resistance (θJA = 46.2°C/W), and compatibility with 1μF ceramic output capacitors.
Technical Context
The AP7366EA-25SN-7 uses a PMOS pass transistor architecture enabling ultra-low dropout and fast transient response. Its internal 0.8V bandgap reference feeds an error amplifier that regulates output by adjusting gate drive to maintain VOUT = 2.5V ±1% across load and line variations.
Enable functionality operates with VIH ≥ 1.0V and VIL ≤ 0.3V, supporting direct microcontroller GPIO control. Protection circuitry includes foldback current limiting (typ. 250mA short-circuit clamp), thermal shutdown at +150°C with +20°C hysteresis, and input overvoltage tolerance up to 6.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5V ±1% accuracy ensures precise core/I/O rail compliance for FPGA and DSP applications. |
| Max Output Current | 600mA continuous delivery supports moderate-power subsystems without external heat sinking in compact layouts. |
| Quiescent Current | 60μA typical enables >1-year battery life in always-on sensor nodes powered by coin cells. |
| Dropout Voltage | 300mV at 600mA allows operation from 2.8V input to sustain 2.5V output in Li-ion single-cell systems. |
| PSRR | 75dB at 1kHz suppresses switching noise from adjacent DC/DC converters feeding shared input rails. |
| Start-up Time | 150μs enables rapid power sequencing in multi-rail systems where timing margins are tight. |
| Thermal Resistance | θJA = 46.2°C/W (U-DFN2020-6) permits 425mW max power dissipation before thermal shutdown at +85°C ambient. |
Pinout & Package
AP7366EA-25SN-7 is housed in a 2.0mm × 2.0mm × 0.6mm U-DFN2020-6 package with wettable flank leads and exposed thermal pad for enhanced PCB heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 3) | Input voltage supply | Accepts 2.2–6V; requires ≥1μF ceramic bypass capacitor placed adjacent to pin for stability and noise rejection. |
| GND (Pin 2) | Power ground reference | Must connect directly to PCB ground plane; serves as return path for IN, OUT, EN, and thermal pad. |
| EN (Pin 1) | Enable control input | Active-high logic interface; ties to MCU GPIO or pull-up resistor; VIH ≥1.0V ensures reliable turn-on. |
| OUT (Pin 4) | Regulated output | Delivers 2.5V ±1%; requires ≥1μF ceramic capacitor to GND for transient stability and ESR < 100mΩ. |
| ADJ (Pin 6) | Feedback reference node | Internally connected to 0.8V reference; left unconnected in fixed-output variants like AP7366EA-25SN-7. |
| NC (Pin 5) | No internal connection | Floating or grounded per layout convenience; no electrical function or signal integrity impact. |
Key Features
| Feature | Design Value |
|---|---|
| Low-IQ regulation | 60μA quiescent current maintains efficiency during deep-sleep modes in IoT edge devices. |
| Fast transient response | Load step recovery within 200μs (50mA→500mA) prevents brownout in burst-mode processors. |
| Stable with minimal capacitance | Guaranteed stability using only 1μF ceramic output capacitor reduces BOM count and board area. |
| Integrated protection | Current limit (250mA short-circuit clamp), thermal shutdown (+150°C), and input overvoltage (6.5V) prevent field failures. |
| Ultra-small footprint | U-DFN2020-6 (2.0×2.0mm) enables high-density power delivery in space-constrained wearables and modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-2502E/MB | Higher dropout (500mV @ 250mA), higher IQ (3.5μA), SOT-23-5 package | Limited to ≤250mA loads; less suitable for high-current FPGA I/O rails | Select when board space allows larger SOT-23 and load current stays below 250mA. |
| Torex XC6219B252MR-G | Same 2.5V fixed output, 600mA rating, but 1.2μA IQ; SOT-25 package | Lower thermal performance (θJA = 139°C/W) limits power density in compact designs | Prefer for ultra-low-power sensor nodes where 600mA peak is rare and thermal margin is ample. |
Compared with MCP1703T-2502E/MB and XC6219B252MR-G, AP7366EA-25SN-7 delivers superior power density via its U-DFN2020-6 package and lower dropout, making it optimal for thermally constrained, high-current portable applications where 60μA IQ remains acceptable.

FAQ
What is the minimum input voltage required for AP7366EA-25SN-7 to regulate 2.5V output at 600mA?
The minimum input voltage is 2.8V, calculated from the 300mV dropout specification at 600mA load. Below this, the device enters dropout mode and cannot maintain regulation. Input must also stay within the absolute maximum rating of 6.5V and recommended operating range of 2.2V–6V.
Can AP7366EA-25SN-7 operate without an external output capacitor?
No. A minimum 1μF ceramic capacitor between OUT and GND is mandatory for stability and transient response. Omitting it causes oscillation and potential damage. The datasheet confirms stability only with ≥1μF low-ESR ceramic capacitors; tantalum or aluminum electrolytics are not recommended due to ESR and reliability concerns.
How does the EN pin behave during power-up, and what pull-up value is recommended?
The EN pin must be driven above 1.0V (VIH) to enable regulation. During power-up, if left floating, internal leakage may cause unpredictable behavior. A 100kΩ pull-up to VIN is recommended to ensure reliable turn-on; the internal EN pull-down resistor is 3MΩ, so external pull-up dominates without excessive current draw.
Is AP7366EA-25SN-7 qualified for automotive applications per AEC-Q100?
No. While rated for -40°C to +85°C ambient operation, AP7366EA-25SN-7 is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., AP7366Q series) with PPAP documentation, IATF 16949 manufacturing, and extended qualification testing-contact Diodes sales for those part numbers.
