Product details
Overview
AP7366EA-28SN-7 from Diodes Incorporated is a fixed-output 2.8V, 600mA low-dropout linear regulator in U-DFN2020-6 package, featuring 60μA quiescent current, 300mV dropout at full load, and integrated enable control. It delivers stable power to FPGA I/O rails and battery-powered microcontrollers where low standby power and fast transient response are critical.
For engineers reviewing the AP7366EA-28SN-7 datasheet, AP7366EA-28SN-7 pinout, AP7366EA-28SN-7 application, or AP7366EA-28SN-7 equivalent, key selection criteria include dropout voltage at 600mA, PSRR at 1kHz, thermal shutdown threshold, EN logic thresholds, and compatibility with 1μF ceramic output capacitors.
Technical Context
The AP7366EA-28SN-7 integrates a PMOS pass element, precision 0.8V bandgap reference, error amplifier, and thermal shutdown circuitry. Its fixed 2.8V output eliminates external feedback resistors, reducing BOM count and layout area while maintaining ±1% output accuracy across load and temperature.
It operates across 2.2V–6V input range and sustains regulation down to 300mV headroom at 600mA. Built-in current limit (≈1A typical) and short-circuit protection (250mA clamp) enable robust operation in fault-prone embedded systems without external current-sense components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8V ±1% at 10mA; ensures precise core/I/O rail compliance for 2.8V logic interfaces. |
| Max Output Current | 600mA continuous; supports mid-power digital loads like FPGA I/O banks or sensor signal chains. |
| Quiescent Current | 60μA typical; enables >1-year battery life in always-on IoT nodes with 200mAh coin cells. |
| Dropout Voltage | 300mV at 600mA; allows operation from single-cell Li-ion (3.0V min) or 3.3V rails with margin. |
| PSRR | 75dB at 1kHz; suppresses switching noise from adjacent DC/DC converters feeding mixed-signal circuits. |
| Start-up Time | 150μs; enables rapid wake-up from deep sleep in portable devices without output undershoot. |
| Thermal Shutdown | Triggers at +150°C with +20°C hysteresis; prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
AP7366EA-28SN-7 uses the U-DFN2020-6 (2.0mm × 2.0mm, 0.65mm height) package with wettable flank leads for automated optical inspection. Thermal pad on underside enhances heat dissipation (θJA = 46.2°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 3) | Input voltage supply | Accepts 2.2V–6V; requires ≥1μF MLCC bypass to GND within 2mm for stability and noise rejection. |
| GND (Pin 2) | Power ground reference | Low-impedance return path; must connect directly to thermal pad and system ground plane. |
| EN (Pin 1) | Enable control input | Active-high logic interface (VIH ≥1.0V); ties to IN for always-on operation or MCU GPIO for dynamic power gating. |
| OUT (Pin 4) | Regulated output | Delivers 2.8V ±1%; requires ≥1μF ceramic capacitor placed adjacent to OUT/GND pins for transient stability. |
| ADJ (Pin 6) | Feedback reference node | Internally connected to 0.8V reference; left unconnected in fixed-output variants-no external resistor required. |
| NC (Pin 5) | No internal connection | Floating or grounded; no electrical function-may be used as thermal relief or mechanical anchor in layout. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 60μA quiescent current enables <10μA system standby when paired with EN-controlled shutdown. |
| Fast transient response | Load step recovery within 200μs (50mA→500mA) minimizes voltage dip on sensitive analog/DSP cores. |
| Single-capacitor stability | Stable with 1μF ceramic output capacitor-reduces board area vs. traditional LDOs requiring ≥10μF. |
| Integrated protection | Current limit, short-circuit clamp (250mA), and thermal shutdown eliminate need for external fault management circuitry. |
| Wide input range | 2.2V–6V operation supports direct connection to Li-ion, USB, or multi-rail intermediate supplies without pre-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-2802E/TT | 300mA max output, 1.6μA IQ, SOT23-5 package, 600mV dropout at 250mA | Lower current capacity; suited for ultra-low-power MCU cores but not FPGA I/O | Select when IQ <2μA is mandatory and load ≤200mA; avoid for 600mA peak loads. |
| Torex XC6210B282MR-G | 500mA max output, 15μA IQ, SOT25 package, 250mV dropout at 300mA | Slightly lower dropout at mid-load; lacks EN pin and thermal hysteresis spec | Prefer for space-constrained designs needing minimal dropout at 300mA; verify EN functionality absence is acceptable. |
Compared with MCP1700T-2802E/TT and XC6210B282MR-G, AP7366EA-28SN-7 uniquely balances 600mA drive, 60μA IQ, and integrated EN/thermal protection in a 2mm² DFN-making it optimal for compact, high-reliability 2.8V I/O rails where both current and efficiency matter.

FAQ
What is the minimum input voltage required for AP7366EA-28SN-7 to maintain 2.8V regulation at 600mA?
The device requires at least 3.1V input (2.8V + 300mV dropout) to sustain regulation at full 600mA load. Below this, output voltage collapses linearly with input; operation below 2.2V input is prohibited per absolute maximum ratings.
Can AP7366EA-28SN-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 and potential damage; larger values (e.g., 4.7μF) further improve load-step immunity.
Is the EN pin internally pulled up or down?
The EN pin has no internal pull-up or pull-down; it presents 3MΩ pull-down resistance (RENPD) per datasheet. To ensure reliable startup, tie EN to IN if unused-or drive with a GPIO capable of ≥1.0V VIH and ≤0.3V VIL thresholds.
Does AP7366EA-28SN-7 require a minimum load current to regulate properly?
No. The regulator remains stable and regulated from zero load to 600mA. Unlike older LDOs, it does not require a minimum load resistor-enabling true zero-power standby when EN is deasserted.
