Product details
Overview
AP7366EA-36W5-7 from Diodes Incorporated is a 600mA fixed-output (3.6V) 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-noise voltage regulation.
For engineers reviewing the AP7366EA-36W5-7 datasheet, AP7366EA-36W5-7 pinout, AP7366EA-36W5-7 application, or AP7366EA-36W5-7 equivalent, key selection criteria include dropout performance at 600mA, thermal resistance (139°C/W), EN logic thresholds (VIH ≥1.0V), PSRR (75dB @1kHz), and compatibility with 1μF ceramic output capacitors.
Technical Context
The AP7366EA-36W5-7 implements a PMOS pass transistor architecture with internal 0.8V bandgap reference and error amplifier for fixed 3.6V output. Its fast transient response is enabled by optimized loop compensation supporting 1μF ceramic output capacitance without external components.
Enable functionality uses active-high logic with 3MΩ internal pull-down resistor and ±0.1μA leakage. Protection circuitry includes foldback current limiting (250mA short-circuit clamp), thermal shutdown at +150°C with +20°C hysteresis, and input overvoltage tolerance up to 6.5V.
Key Specifications

Pinout & Package
SOT25 package (3.0mm × 2.8mm × 1.3mm) with exposed thermal pad not connected internally; requires soldering to PCB ground plane for thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input voltage supply | Bypassed with ≥1μF MLCC; must be routed with low-inductance trace to minimize noise coupling |
| 2 - GND | Power ground reference | Shared return path for IN, OUT, and EN; connects to thermal pad for heat dissipation |
| 3 - EN | Enable control input | Active-high logic: drives high (>1.0V) to activate regulator; pulled low (<0.3V) disables output |
| 4 - NC | No internal connection | Left floating or tied to GND; no electrical impact on regulation or protection functions |
| 5 - OUT | Regulated output voltage | Requires ≥1μF ceramic capacitor to GND; placement within 2mm of pin critical for transient stability |
Key Features
| Feature | Design Value |
|---|---|
| Low ESR capacitor support | Stable with 1μF ceramic output capacitor-reduces BOM count and board space vs. larger tantalum solutions |
| Fast load transient response | ≤20mV undershoot/overshoot during 100mA→500mA step changes at 3.6V output |
| Integrated thermal protection | Auto-recovery shutdown at +150°C junction temperature prevents permanent damage during overload |
| Ultra-low IQ operation | 60μA quiescent current maintains efficiency in standby modes without sacrificing start-up speed |
| High PSRR at audio frequencies | 75dB rejection at 1kHz enables clean power for analog-sensitive circuits adjacent to digital noise sources |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3602E/TT | 250mA max output, 1.6μA IQ, SOT23-5 package | Limited to ultra-low-power sensors; insufficient for 600mA FPGA I/O loads | Select only when quiescent current <2μA is mandatory and load current ≤250mA |
| TLS850B2TE/VX | Automotive-grade AEC-Q100 qualified, 500mA, 35μA IQ, wider temp range (−40°C to +150°C) | Designed for under-hood automotive use; higher cost and qualification overhead for industrial apps | Choose for automotive programs requiring PPAP documentation and extended temperature operation |
Compared with MCP1700T-3602E/TT and TLS850B2TE/VX, the AP7366EA-36W5-7 uniquely balances 600mA capability with 60μA IQ in a standard SOT25 footprint-making it optimal for cost-sensitive industrial and portable designs where automotive qualification is unnecessary but higher current than micro-power LDOs is required.

FAQ
What is the minimum input voltage required for AP7366EA-36W5-7 to maintain regulation?
The AP7366EA-36W5-7 requires a minimum input voltage of 3.9V to sustain 3.6V output at 600mA load, based on its 300mV dropout specification. At lighter loads, input can drop to 3.7V (100mV dropout) while maintaining regulation. Input below 2.2V is outside operational limits per datasheet absolute maximum ratings.
Can AP7366EA-36W5-7 operate without an output capacitor?
No-AP7366EA-36W5-7 requires a minimum 1μF ceramic capacitor between OUT and GND for stability, as confirmed in the Electrical Characteristics table and Application Information section. Omitting this capacitor causes oscillation and unregulated output, regardless of load condition or enable state.
Is the EN pin internally pulled down, and what drive strength is needed?
Yes-the EN pin has a 3MΩ internal pull-down resistor, allowing safe default-off behavior. Driving EN requires only logic-level signals: VIH ≥1.0V and VIL ≤0.3V, with leakage current limited to ±0.1μA. No external pull-up/down resistors are needed unless interfacing with open-drain controllers.
How does thermal shutdown behave during sustained overload?
When junction temperature reaches +150°C, thermal shutdown disables the output; recovery occurs automatically at +130°C due to +20°C hysteresis. Under continuous overload, this causes on/off cycling-visible as output voltage pulsing at intervals determined by power dissipation, ambient temperature, and PCB thermal mass.
