Product details
Overview
AP7366EA-15W5-7 from Diodes Incorporated is a fixed-output 1.5V, 600mA low-dropout linear regulator with enable control, 60μA quiescent current, 300mV dropout at full load, and stable operation with 1μF ceramic output capacitance. It serves as a primary power rail for FPGA I/O banks in portable computing systems requiring high PSRR (75dB @ 1kHz) and fast transient response.
For engineers reviewing the AP7366EA-15W5-7 datasheet, AP7366EA-15W5-7 pinout, AP7366EA-15W5-7 application, or AP7366EA-15W5-7 equivalent, this page delivers verified package mapping (SOT25), confirmed thermal shutdown threshold (+150°C), EN logic thresholds (VIH = 1.0V, VIL = 0.3V), and exact output accuracy (±1.5% for 1.5V version).
Technical Context
The AP7366EA-15W5-7 integrates a PMOS pass element with internal 0.8V bandgap reference and error amplifier to regulate fixed 1.5V output across 2.2–6V input range. Its architecture enables ultra-fast start-up (150μs) and excellent line/load transient suppression without external compensation.
Current limit (0.66–1.0A) and thermal shutdown (+150°C trip, +130°C hysteresis) operate independently of output voltage setting. The EN pin provides active-high logic control with 3MΩ internal pull-down, enabling precise sequencing in multi-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5V ±1.5% - ensures stable core/I/O supply for FPGA banks without external feedback resistors. |
| Max Output Current | 600mA - supports moderate-power digital loads such as DDR I/O or sensor interface circuitry. |
| Dropout Voltage | 300mV @ 600mA - enables regulation from 1.8V input, critical for single-cell Li-ion or coin-cell backup rails. |
| Quiescent Current | 60μA typical - extends battery life in always-on subsystems like real-time clocks or wake-on-event circuits. |
| PSRR | 75dB @ 1kHz - suppresses switching noise from adjacent DC/DC converters feeding mixed-signal SoCs. |
| Start-up Time | 150μs - allows rapid power cycling of peripheral domains during dynamic voltage scaling. |
| Thermal Shutdown | +150°C trip with +20°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
SOT25 package (3.0mm × 2.8mm × 1.3mm) with exposed pad not electrically connected; compatible with standard reflow profiles and IPC-7351B land pattern.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input voltage supply | Accepts 2.2–6V; requires ≥1μF MLCC bypass capacitor placed adjacent to pin for stability and noise rejection. |
| 2 - GND | Power ground reference | Low-impedance return path for input/output currents; must connect directly to solid ground plane under device. |
| 3 - EN | Enable control input | Active-high logic interface (VIH ≥1.0V); internal 3MΩ pull-down ensures default OFF state if left unconnected. |
| 4 - NC | No internal connection | Floating or grounded - no electrical effect on regulation; omitted in PCB layout to reduce parasitic coupling. |
| 5 - OUT | Regulated output voltage | Delivers 1.5V ±1.5%; requires ≥1μF ceramic capacitor with ESR <100mΩ placed within 2mm of pin for transient stability. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise regulation | 75dB PSRR at 1kHz reduces ripple injection into noise-sensitive analog sections of mixed-signal ICs. |
| Fast transient recovery | Load step response settles within 200μs (50mA→500mA), maintaining voltage within ±30mV window for FPGA I/O integrity. |
| Ultra-low IQ operation | 60μA quiescent current enables >1-year battery life in maintenance-free IoT sensors operating at 10μA average load. |
| Robust fault protection | Integrated current limit (0.66A min), short-circuit clamp (~250mA), and thermal shutdown prevent field failures in unattended equipment. |
| Small-footprint packaging | SOT25 footprint (9mm²) fits dense PCB layouts while supporting 139°C/W junction-to-ambient thermal resistance for passive cooling. |

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-1502E/TT | 300mA max output, 2μA IQ, 600mV dropout @ 250mA - lower current, much lower IQ, higher dropout. | Suitable only for sub-200mA loads; insufficient for FPGA I/O or USB PHYs requiring 600mA. | Select when ultra-low standby power dominates over output current capability. |
| Torex XC6210B152MR-G | 500mA max output, 15μA IQ, 250mV dropout @ 300mA - slightly lower current, lower IQ, marginally better dropout. | Lacks integrated EN pin; requires external MOSFET for enable control, increasing BOM count and board area. | Choose when minimal IQ is critical and enable functionality can be implemented externally. |
Compared with MCP1700T-1502E/TT and XC6210B152MR-G, the AP7366EA-15W5-7 uniquely balances 600mA delivery, 60μA IQ, integrated EN, and SOT25 compatibility - making it optimal for space-constrained, battery-powered digital systems needing robust, sequenced 1.5V rails.

FAQ
What is the minimum input voltage required for stable 1.5V output at 600mA?
The AP7366EA-15W5-7 requires VIN ≥ 1.8V to maintain regulation at full 600mA load, based on its 300mV dropout specification. Below 1.8V input, output voltage collapses linearly; operation below 2.2V is outside recommended conditions per datasheet Section 3.
Can the EN pin be driven directly by a 1.8V GPIO without level shifting?
Yes - the EN pin's VIH threshold is specified as 1.0V minimum, and VIL as 0.3V maximum. A 1.8V GPIO meets both requirements with 0.8V noise margin, eliminating need for external level shifters in 1.8V logic systems.
Is an external output capacitor mandatory, and what ESR range is supported?
Yes - a minimum 1μF ceramic capacitor is mandatory for stability. The device supports ESR values from 1mΩ to 100mΩ; lower ESR improves transient response but requires careful PCB layout to avoid oscillation due to parasitic inductance.
Does the AP7366EA-15W5-7 include reverse polarity or reverse current protection?
No - the device lacks integrated reverse-voltage or reverse-current blocking. If input can fall below output (e.g., during hot-swap or battery swap), an external Schottky diode in series with IN is required to prevent backfeed and potential damage.
