Product details
Overview
AP7366EA-10W5-7 from Diodes Incorporated is a 600mA fixed-output (1.0V) low-dropout linear regulator in SOT25 package, featuring 60μA quiescent current, 300mV dropout at full load, and integrated enable control. It delivers stable power to FPGA I/O rails, DSP cores, and battery-powered consumer electronics requiring precise low-voltage regulation.
For engineers reviewing the AP7366EA-10W5-7 datasheet, AP7366EA-10W5-7 pinout, AP7366EA-10W5-7 application, or AP7366EA-10W5-7 equivalent, this device supports fast transient response (150μs startup), high PSRR (75dB @1kHz), and operation across -40°C to +85°C ambient with minimal external components.
Technical Context
The AP7366EA-10W5-7 integrates a PMOS pass element, precision 0.8V bandgap reference, and error amplifier for tight output regulation. Its thermal shutdown triggers at +150°C with +20°C hysteresis, and current limit activates at ~1.0A to protect against overload and short-circuit conditions.
Designed for low-noise, low-power systems, it achieves stability with only 1μF ceramic output capacitance and maintains ±1% output accuracy over load (1mA–600mA) and line (2.2V–6V input) variations. The EN pin enables logic-level on/off control with 1.0V VIH threshold and 3MΩ internal pull-down resistor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0V ±1.5% accuracy ensures reliable powering of 1.0V FPGA I/O banks without external feedback resistors. |
| Max Output Current | 600mA continuous delivery supports mid-power digital loads like microcontroller peripherals or sensor interfaces. |
| Quiescent Current | 60μA typical enables >1-year battery life in always-on IoT sensors operating from coin cells. |
| Dropout Voltage | 300mV at 600mA allows operation from 1.3V input-critical for single-cell Li-ion or LiFePO₄ systems. |
| PSRR | 75dB at 1kHz suppresses switching noise from adjacent DC/DC converters feeding mixed-signal circuits. |
| Startup Time | 150μs enables rapid wake-up from deep sleep in portable devices without voltage droop-induced resets. |
| Thermal Shutdown | +150°C trip point 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 thermal pad not connected internally; requires soldering to PCB copper for thermal performance. Pin 1 = IN, Pin 2 = GND, Pin 3 = EN, Pin 4 = NC, Pin 5 = OUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Input voltage supply | Accepts 2.2V–6V; must be bypassed with ≥1μF MLCC close to pin to suppress ripple and ensure stability. |
| GND (Pin 2) | Power ground reference | Low-impedance return path for input/output currents; connects to main system ground plane. |
| EN (Pin 3) | Enable control input | Active-high logic interface; drives ON when ≥1.0V applied; internal 3MΩ pull-down keeps regulator off if floating. |
| NC (Pin 4) | No internal connection | Unbonded terminal; must remain unconnected-no routing or grounding required. |
| OUT (Pin 5) | Regulated output voltage | Delivers 1.0V ±1.5% to load; requires ≥1μF ceramic capacitor to GND for transient response and stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 60μA quiescent current minimizes standby power loss-enables multi-year operation from CR2032 batteries. |
| Fast transient response | Load step recovery within 200μs (50mA→500mA) prevents brownouts in burst-mode processors. |
| Low-ESR capacitor compatibility | Stable with 1μF ceramic output cap-eliminates need for costly tantalum or polymer capacitors. |
| Integrated protection | Current limit (~1.0A), short-circuit clamp (~250mA), and thermal shutdown prevent field failures under fault conditions. |
| Wide input range | 2.2V–6V operation supports direct connection to USB, Li-ion, or buck converter outputs without pre-regulation. |
Applications
| FPGA I/O Power Supply | DSP Core Voltage Rail |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-1002E/TO | 300mA max output, 2.0μA IQ, TO-92 package; lacks EN pin and thermal shutdown. | Only suitable for ultra-low-power (<300mA), non-automotive applications where enable control is unnecessary. | Select only if IQ <2.0μA is mandatory and load current never exceeds 300mA-no drop-in replacement. |
| Torex XC6210B102MR-G | 1.0V fixed, 500mA, 1.0μA IQ, SOT-25; no current limit or thermal shutdown. | Applicable only in thermally benign environments with strict <1.0μA IQ requirements and known safe load profiles. | Choose only for niche ultra-low-IQ designs where protection features are handled externally-requires redesign. |
Compared with MCP1700-1002E/TO and XC6210B102MR-G, the AP7366EA-10W5-7 provides 2× higher current capability, integrated enable control, and full fault protection-making it the sole option for robust, production-ready 1.0V/600mA regulation in space-constrained, battery-operated systems.

FAQ
What is the minimum input voltage required for 1.0V output regulation at 600mA?
The AP7366EA-10W5-7 requires a minimum input voltage of 1.3V to maintain 1.0V output at 600mA load, based on its 300mV dropout specification. Below this, output voltage collapses proportionally; operation below 2.2V input is not recommended per absolute maximum ratings.
Can the EN pin be left unconnected, or does it require external biasing?
The EN pin must not be left floating: it has an internal 3MΩ pull-down resistor that holds the regulator OFF by default. To enable operation, connect EN directly to IN or to a logic-high signal ≥1.0V. Leaving it unconnected results in no output voltage.
Is a minimum load required for output stability with the AP7366EA-10W5-7?
No minimum load is required-the AP7366EA-10W5-7 remains stable and regulated down to zero load current. This is confirmed in the datasheet's "No Load Stability" section and enables use in always-on monitoring circuits with intermittent active periods.
What thermal considerations apply when using the SOT25 package at full 600mA load?
At 600mA and 2.2V input (1.2V drop), power dissipation reaches 720mW. With θJA = 139°C/W, junction temperature rise is ~100°C above ambient-requiring adequate PCB copper area (≥100mm² thermal pad) to avoid thermal shutdown at +85°C ambient.
