Product details
Overview
AP7366EA-28W5-7 from Diodes Incorporated is a fixed-output 2.8V, 600mA low-dropout linear regulator with enable control, 60μA quiescent current, and 300mV dropout at full load. It integrates current limit, thermal shutdown, and stable operation with 1μF ceramic output capacitance-designed for battery-powered portable electronics requiring precise, low-noise power delivery.
For engineers reviewing the AP7366EA-28W5-7 datasheet, AP7366EA-28W5-7 pinout, AP7366EA-28W5-7 application, or AP7366EA-28W5-7 equivalent, key selection criteria include its 2.8V fixed output, SOT25 package footprint, EN-active-high logic interface, low 60μA IQ, and compatibility with minimal 1μF output capacitors in space-constrained designs.
Technical Context
The AP7366EA-28W5-7 implements a PMOS pass transistor architecture enabling ultra-low dropout (300mV @ 600mA) and high PSRR (75dB @ 1kHz). Its internal 0.8V bandgap reference and error amplifier regulate output with ±1% accuracy across temperature and load.
Enable functionality uses TTL/CMOS-compatible thresholds (VIH ≥ 1.0V, VIL ≤ 0.3V), while built-in protection includes foldback current limiting (250mA short-circuit clamp), thermal shutdown at +150°C with +20°C hysteresis, and EN pull-down resistor (3MΩ).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8V ±1% - ensures stable core/I/O rail for 2.8V logic systems without external feedback components. |
| Max Output Current | 600mA - supports moderate-power FPGA I/O banks or microcontroller peripherals without derating at +85°C ambient. |
| Quiescent Current | 60μA typical - extends battery life in always-on sensor nodes or standby modes of portable devices. |
| Dropout Voltage | 300mV @ 600mA - enables regulation from 3.1V input (e.g., single Li-ion cell post-LDO), minimizing power loss. |
| PSRR | 75dB @ 1kHz - suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Start-up Time | 150μs - allows rapid power sequencing in multi-rail systems where timing-critical subsystems require fast voltage ramp. |
| Thermal Shutdown | +150°C threshold with +20°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
| Input Voltage Range | 2.2V to 6.0V - accommodates single-cell Li-ion (2.7–4.2V), USB 5V, or regulated 3.3V/5V rails. |
Pinout & Package
SOT25 (5-pin) package with exposed pad not electrically connected; compact 2.8mm × 2.9mm footprint optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input voltage supply | Bypassed with ≥1μF MLCC close to pin; accepts 2.2–6V; powers internal regulator circuitry. |
| 2 - GND | Ground reference | Primary return path for input/output currents; must connect to low-impedance ground plane for stability. |
| 3 - EN | Enable control input | Active-high logic: ≥1.0V enables output; ≤0.3V disables output and reduces IQ to 0.05μA. |
| 4 - NC | No internal connection | Float or tie to GND; no electrical function-mechanical placeholder for SOT25 pin count consistency. |
| 5 - OUT | Regulated output | Delivers 2.8V ±1%; requires ≥1μF ceramic capacitor to GND for transient stability and ESR tolerance. |
Key Features
| Feature | Design Value |
|---|---|
| Low-IQ operation | 60μA quiescent current enables >1-year battery life in 10μA average-load IoT sensors. |
| Fast transient response | Load step recovery within 200μs (50mA→500mA) minimizes voltage dip on FPGA I/O banks during burst activity. |
| Single-capacitor stability | Stable with 1μF ceramic output capacitor-reduces BOM count and board area vs. legacy LDOs requiring ≥10μF. |
| Integrated protection | Current limit (250mA short-circuit clamp), thermal shutdown (+150°C), and EN-controlled shutdown prevent field failures. |
| Wide input range | 2.2V–6V operation supports direct connection to Li-ion, USB, or industrial 3.3V/5V supplies without pre-regulation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.

|---|---|---|---|
| MCP1700T-2802E/MB | 250mA max output, 1.6μA IQ, 600mV dropout @ 250mA | Lower current capacity; better for ultra-low-power sub-100mA sensors only | Select when IQ < 2μA is mandatory and load ≤250mA; avoid for FPGA I/O or USB peripherals. |
| Torex XC6210B282MR-G | 400mA max output, 15μA IQ, 250mV dropout @ 400mA, 1.5mm × 1.5mm DFN | Smaller footprint but lower current; lacks EN pin | Choose for space-constrained designs with ≤400mA loads and no enable requirement; verify thermal performance at full load. |

FAQ
What is the minimum input voltage required for stable 2.8V output at 600mA?
The AP7366EA-28W5-7 requires VIN ≥ 3.1V to maintain regulation at 600mA due to its 300mV dropout specification. Below this, output voltage collapses linearly with input; operation below 2.2V is prohibited per absolute maximum ratings.
Can the AP7366EA-28W5-7 be used without an 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 device failure under load transients, as confirmed by the datasheet's stability conditions and application circuits.
Is the EN pin internally pulled down when left unconnected?
Yes. The EN pin features a 3MΩ internal pull-down resistor, ensuring the device remains disabled if the pin is floating. However, for robust noise immunity in noisy environments, Diodes recommends tying EN directly to GND or IN via a hard connection rather than relying solely on the internal resistor.
Does the AP7366EA-28W5-7 support reverse polarity protection?
No. The device lacks integrated reverse-voltage protection. Applying negative voltage to IN or OUT relative to GND may damage the IC. External protection (e.g., series Schottky diode or dedicated reverse-protection IC) is required in systems prone to incorrect battery insertion or supply reversal.
