Product details
Overview
AP7366-15W5-7 from Diodes Incorporated is a fixed-output 1.5V, 600mA low-dropout linear regulator in SOT25 package with enable control, 60μA quiescent current, 300mV dropout at full load, and 75dB PSRR at 1kHz-designed for FPGA I/O rail regulation in battery-powered portable electronics.
For engineers reviewing the AP7366-15W5-7 datasheet, AP7366-15W5-7 pinout, AP7366-15W5-7 application, or AP7366-15W5-7 equivalent, key selection criteria include dropout voltage at 600mA, EN logic thresholds (VIH = 1.0V, VIL = 0.3V), thermal shutdown threshold (+150°C), and stability with 1μF ceramic output capacitor.
Technical Context
The AP7366-15W5-7 integrates a PMOS pass element, precision 0.8V bandgap reference, and error amplifier to deliver tightly regulated 1.5V output across -40°C to +85°C ambient. Its current-limit circuit triggers at 0.66A and short-circuit protection clamps output to ~250mA when OUT shorts to GND.
Thermal shutdown activates at +150°C junction temperature with +20°C hysteresis, enabling automatic recovery at +130°C. The device achieves 150μs start-up time from EN assertion to 3V output under 30Ω load, supporting rapid power-state transitions in portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5V ±1.5% accuracy at 10mA load ensures stable core/I/O supply for low-voltage logic. |
| Max Output Current | 600mA continuous delivery supports FPGA I/O banks or microcontroller peripherals without derating. |
| Dropout Voltage | 300mV at 600mA enables operation from 1.8V input-critical for single-cell Li-ion or Li-poly systems. |
| Quiescent Current | 60μA typical enables >1-year battery life in always-on sensor nodes with 200mAh coin cell. |
| PSRR | 75dB at 1kHz suppresses switching noise from adjacent DC/DC converters feeding shared input rails. |
| Start-Up Time | 150μs ensures sub-millisecond wake-up from deep sleep in real-time embedded control loops. |
| Thermal Shutdown | +150°C activation 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 for thermal enhancement; JEDEC MO-203AA compliant; RoHS and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input voltage supply | Accepts 2.2V–6V; requires ≥1μF MLCC bypass to GND within 2mm trace length for stability. |
| 2 - GND | Power ground reference | Low-impedance return path; must connect directly to thermal pad and system ground plane. |
| 3 - EN | Enable control input | Active-high logic interface; VIH ≥1.0V, VIL ≤0.3V; internal 3MΩ pulldown allows default ON if unconnected. |
| 4 - NC | No connection | Unbonded die pad; must remain floating-no PCB trace or copper pour allowed. |
| 5 - OUT | Regulated output | Delivers 1.5V ±1.5%; requires ≥1μF ceramic capacitor placed <1mm from OUT/GND pins. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 60μA quiescent current minimizes standby power loss-enables multi-year operation on primary batteries. |
| Fast transient response | Load step recovery <200μs (100mA→500mA) maintains voltage within ±20mV for noise-sensitive analog circuits. |
| Low-ESR capacitor support | Stable with 1μF ceramic output capacitor (10–300mΩ ESR), reducing BOM count and PCB area vs. electrolytic solutions. |
| Integrated protection | Current limit (0.66A), short-circuit clamp (~250mA), and thermal shutdown (+150°C) eliminate need for external fault management. |
| Wide input range | 2.2V–6V operation accommodates single-cell Li-ion (2.7–4.2V), USB (4.75–5.25V), and industrial 5V rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-1502E/TO | 300mA max output, 2.0V–6.0V input, 1.8μA IQ, SOT23-3 package (no EN) | Lacks enable pin and current capability; unsuitable for dynamic load scenarios requiring fast wake-up. | Select only for static, ultra-low-power sensor nodes where 300mA headroom and EN control are unnecessary. |
| Torex XC6219B152MR-G | 600mA output, 1.5V fixed, 1.0μA IQ, SOT25 package, but no thermal shutdown or current limit | Relies on external protection; not robust for field-deployed equipment with variable thermal environments. | Prefer only in cost-sensitive consumer devices with controlled thermal profiles and no risk of sustained overload. |

FAQ
What is the minimum input voltage required for stable 1.5V output at 600mA?
The AP7366-15W5-7 requires VIN ≥ 1.8V to maintain regulation at full 600mA load, based on its 300mV dropout specification. Below 1.8V, output voltage collapses proportionally; operation below 2.2V is outside recommended conditions per datasheet Section 5.
Can the AP7366-15W5-7 be used without an external output capacitor?
No. A minimum 1μF ceramic output capacitor is mandatory for stability, as confirmed in Section 8.2 of the datasheet. Omitting it causes oscillation and voltage overshoot during load transients-verified by load-step testing in Figure 12.
Does the EN pin require a pull-up resistor for reliable operation?
No. The EN pin has an internal 3MΩ pulldown resistor (RENPD), so tying it directly to IN ensures default ON operation without external components. A pull-up is only needed if active-low logic control is required, which is not supported by this part's active-high EN architecture.
How does thermal shutdown behave under sustained overload?
When junction temperature reaches +150°C, the device disables output and remains off until temperature drops to +130°C (20°C hysteresis). Under continuous overload, this causes on/off cycling-observed in thermal characterization plots (Figure 10) and validated via hot-plate testing at 85°C ambient.
