Product details
Overview
AP7366-10W5-7 from Diodes Incorporated is a fixed-output 1.0V, 600mA low-dropout linear regulator in SOT25 package with 60μA quiescent current, 300mV dropout at full load, and enable control. It delivers stable core voltage for FPGA I/O rails and portable microcontroller subsystems operating from 2.2V–6V input sources.
For engineers reviewing the AP7366-10W5-7 datasheet, AP7366-10W5-7 pinout, AP7366-10W5-7 application, or AP7366-10W5-7 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 AP7366-10W5-7 integrates a PMOS pass element, bandgap reference, error amplifier, and thermal shutdown circuitry. Its fixed 1.0V output eliminates external feedback resistors, simplifying layout while maintaining ±1.5% output accuracy across load and temperature.
It operates with an input range of 2.2V to 6V and achieves 75dB PSRR at 1kHz due to internal compensation optimized for 1μF ceramic output capacitance. The EN pin provides active-high logic control with 1.0V VIH and 0.3V VIL thresholds, enabling direct interfacing with 1.8V/3.3V GPIOs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0V ±1.5% (ensures reliable 1.0V core supply for low-voltage I/O domains) |
| Max Output Current | 600mA (supports moderate-power digital loads without external boost) |
| Quiescent Current | 60μA typical (enables >1-year battery life in always-on sensor nodes) |
| Dropout Voltage | 300mV at 600mA (allows operation down to 1.3V input for single-cell Li-ion systems) |
| PSRR | 75dB at 1kHz (suppresses switching noise from adjacent DC-DC converters) |
| Start-Up Time | 150μs (enables rapid power sequencing in multi-rail systems) |
| Thermal Shutdown | 150°C threshold with 20°C hysteresis (prevents permanent damage during sustained overload) |
| Operating Temp | −40°C to +85°C ambient (validates use in industrial edge controllers and automotive cabin modules) |
Pinout & Package
SOT25 package (3.0mm × 2.8mm × 1.3mm) with exposed thermal pad on bottom side; requires minimum 1oz copper thermal plane per Diodes recommended layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input voltage supply | Bypassed to GND with ≥1μF MLCC; must be routed with low-inductance trace to minimize noise coupling |
| 2 - GND | Power ground reference | Common return path for IN, OUT, and EN; connects directly to thermal pad for heat dissipation |
| 3 - EN | Enable control input | Active-high logic interface; tied to IN for always-on operation or driven by MCU GPIO |
| 4 - NC | No connection | Internally unconnected; must remain floating or grounded per layout guidelines to avoid parasitic coupling |
| 5 - OUT | Regulated output | Supplies 1.0V load; bypassed with 1μF ceramic capacitor placed adjacent to pin for transient stability |
Key Features
| Feature | Design Value |
|---|---|
| Low ESR capacitor support | Stable with 1μF ceramic output capacitor (reduces BOM count and PCB area vs. larger tantalum solutions) |
| Fast transient response | Load step recovery within 200μs (maintains voltage integrity during CPU burst activity) |
| Integrated protection | Current limit (≈1A), short-circuit clamp (250mA), and thermal shutdown (150°C) prevent field failures |
| Ultra-low IQ | 60μA quiescent current independent of input voltage (critical for energy harvesting and coin-cell applications) |
| Wide VIN range | 2.2V–6V operation supports single-cell Li-ion, USB, and legacy 5V rails without pre-regulation |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-1002E/MB | Higher 125μA IQ; 250mV dropout at 250mA; no EN pin | Lacks enable control; unsuitable for dynamic power gating | Select only if system requires no enable functionality and can tolerate higher IQ |

FAQ
What is the minimum input voltage required for stable 1.0V output at 600mA?
The AP7366-10W5-7 requires a minimum input voltage of 1.3V to maintain regulation at 600mA, based on its 300mV dropout specification. Below this, output voltage collapses linearly with input; operation below 2.2V is not recommended due to degraded PSRR and thermal performance.
Can the AP7366-10W5-7 be used without an output capacitor?
No. A minimum 1μF ceramic output capacitor is mandatory for stability and transient response. Omitting it causes oscillation and potential device failure under load transients. The datasheet explicitly states stability is guaranteed only with ≥1μF ceramic capacitance and ESR between 10mΩ and 300mΩ.
Does the EN pin require a pull-up resistor when unused?
No. When enable functionality is not needed, the EN pin must be directly connected to the IN pin-not pulled up via a resistor-to ensure full turn-on and avoid leakage-induced partial enable states. A resistor introduces unnecessary voltage drop and may cause marginal activation near VIH threshold.
Is the AP7366-10W5-7 qualified for automotive applications?
The AP7366-10W5-7 is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., AP7366Q series) with PPAP documentation and IATF 16949 manufacturing; this part is intended for industrial and commercial use only. Use only after verifying ambient and reliability requirements match the −40°C to +85°C spec.
