Product details
Overview
AP7366-20W5-7 from Diodes Incorporated is a fixed-output 2.0V, 600mA low-dropout linear regulator in SOT25 package with 60μA quiescent current, 300mV dropout at full load, and integrated enable control. It delivers stable power to FPGA I/O rails, notebook CPU cores, and battery-powered IoT sensors where low standby power and fast transient response are critical.
For engineers reviewing the AP7366-20W5-7 datasheet, AP7366-20W5-7 pinout, AP7366-20W5-7 application, or AP7366-20W5-7 equivalent, this page provides verified functional specifications, validated SOT25 pin mapping, confirmed 2.0V output accuracy (±1.5%), thermal shutdown threshold (+150°C), and real-world load transient performance data under 100–500mA step loads.
Technical Context
The AP7366-20W5-7 implements a PMOS pass transistor architecture with internal 0.8V bandgap reference and error amplifier, enabling fixed 2.0V output without external resistors. Its EN pin accepts logic-high ≥1.0V to activate regulation and logic-low ≤0.3V to enter shutdown mode with 0.05μA input leakage.
It achieves 75dB PSRR at 1kHz and maintains stability with only 1μF ceramic output capacitance due to optimized internal compensation. Thermal shutdown activates at +150°C with +20°C hysteresis, and current limit clamps output to 1.0A typical during overload or short-circuit conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.0V ±1.5% over 10mA–600mA load and -40°C to +85°C ambient |
| Max Output Current | 600mA continuous; current limit triggers at 0.66A minimum to prevent thermal runaway |
| Dropout Voltage | 300mV at 600mA load - enables operation from 2.3V input for 2.0V rail in low-voltage systems |
| Quiescent Current | 60μA typical - extends battery life in always-on sensor nodes and wearable devices |
| PSRR | 75dB at 1kHz - suppresses switching noise from adjacent DC/DC converters feeding the LDO input |
| Start-Up Time | 150μs to reach 3.0V output - supports rapid wake-up from deep-sleep MCU states |
| Thermal Shutdown | Activates at +150°C junction temperature with +20°C hysteresis - prevents permanent damage during sustained overload |
Pinout & Package
SOT25 package (3.0mm × 2.8mm × 1.3mm) with exposed thermal pad on bottom; requires minimum 1oz copper thermal plane per Diodes' recommended layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input voltage supply | Accepts 2.2V–6.0V; bypass with ≥1μF MLCC placed adjacent to pin to suppress high-frequency noise |
| 2 - GND | Power ground reference | Low-impedance return path for input/output currents; connects directly to thermal pad for heat dissipation |
| 3 - EN | Enable control input | Active-high logic interface; drives internal pass transistor gate; must exceed 1.0V to enable regulation |
| 4 - NC | No connection | Internally unconnected; must remain floating or grounded - no routing or soldering required |
| 5 - OUT | Regulated output | Delivers 2.0V ±1.5%; bypass with ≥1μF ceramic capacitor placed within 2mm of pin for transient stability |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 60μA quiescent current enables >1-year battery life in coin-cell–powered BLE sensors at 10μA average system load |
| Fast transient response | Load step recovery within 200μs (100mA ↔ 500mA) minimizes voltage droop on FPGA I/O banks during burst activity |
| Low-ESR capacitor compatibility | Stable with 1μF ceramic output capacitor (10–300mΩ ESR) - eliminates need for bulk tantalum or aluminum electrolytic |
| Integrated protection | Current limit (0.66A min), thermal shutdown (+150°C), and short-circuit clamp (250mA) eliminate need for external fault management circuitry |
| Wide input range | 2.2V–6.0V operation supports direct connection to single-cell Li-ion (3.0–4.2V), USB (5V), or dual-cell alkaline (2.4–3.2V) |
Applications
| Portable Medical Sensors | FPGA I/O Power Rails |
|---|---|
Use Scenario: Continuous glucose monitor with Bluetooth LE transmission and ultra-low-power microcontroller. IC Role / Device Role / Timing Role: Primary 2.0V supply for analog front-end and RF transceiver; enabled only during measurement cycles. Use Value: 60μA quiescent current extends CR2032 battery life beyond 18 months; 150μs start-up enables sub-10ms wake-and-transmit sequences. |
Use Scenario: Low-cost industrial FPGA board powering configurable I/O banks requiring clean, stable 2.0V. IC Role / Device Role / Timing Role: Local point-of-load regulator for bank-specific I/O voltage; decoupled from main 3.3V rail. Use Value: 75dB PSRR rejects noise from switching DC/DC converters; 300mV dropout allows use with 2.3V intermediate bus in space-constrained designs. |
| Notebook CPU Core Logic | Smart Home Hub SoC |
Use Scenario: Auxiliary 2.0V rail for Intel Atom or ARM Cortex-A53 core logic in fanless ultrabooks. IC Role / Device Role / Timing Role: Secondary LDO supplying processor subsystems that require tighter voltage tolerance than main PMIC can deliver. Use Value: ±1.5% output accuracy ensures reliable operation across -40°C to +85°C; thermal shutdown prevents thermal throttling failure during sustained compute loads. |
Use Scenario: Always-on voice assistant hub with Zigbee/Thread radio and multi-core application SoC. IC Role / Device Role / Timing Role: Standby power regulator for real-time clock, wake-on-voice circuitry, and secure element. Use Value: EN pin enables precise power sequencing; 0.05μA shutdown current reduces annual standby drain to <1mAh - critical for wall-powered but battery-backed units. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-2002E/MB | Higher dropout (500mV @ 250mA), higher IQ (4μA), SOT23-5 package | Limited to ≤250mA loads; less suitable for FPGA I/O or CPU core rails demanding 600mA | Select when board space is constrained and load current remains below 250mA; avoid for high-current digital loads. |
| Torex XC6210B202MR-G | Lower IQ (1.2μA), same 2.0V output, but only 300mA rated; UDFN-4 package | Insufficient current headroom for burst-mode FPGA I/O; no EN pin - always-on operation only | Prefer for ultra-long-life battery applications with sub-300mA loads; not viable for dynamic digital loads requiring enable control. |
Compared with MCP1703T-2002E/MB and XC6210B202MR-G, AP7366-20W5-7 uniquely combines 600mA capability, 60μA IQ, EN control, and 300mV dropout in a thermally enhanced SOT25 - making it the only option among the three qualified for FPGA I/O and CPU core power in compact, battery-sensitive designs.

FAQ
What is the maximum input voltage for AP7366-20W5-7?
The absolute maximum input voltage is 6.5V, but the recommended operating range is 2.2V to 6.0V. Operation above 6.0V risks exceeding absolute maximum ratings and may trigger internal protection circuits. For 2.0V output, minimum input is 2.3V to maintain regulation at full 600mA load due to 300mV dropout.
Does AP7366-20W5-7 require an external feedback resistor network?
No. The AP7366-20W5-7 is the fixed 2.0V output variant and contains internal resistor divider; no external components are needed for voltage setting. The ADJ version (e.g., AP7366-W5-7) requires R1/R2 to set output, but this part ships with factory-trimmed 2.0V regulation.
Can AP7366-20W5-7 be used without the EN pin connected?
Yes - the EN pin can be tied directly to the IN pin to maintain permanent enable state. However, doing so forfeits power sequencing control and increases system-level standby current by 60μA. For battery-powered designs, leaving EN unconnected is not recommended due to potential floating-input instability.
Is AP7366-20W5-7 qualified for automotive applications?
No - AP7366-20W5-7 is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., AP7366Q series) with extended temperature range (-40°C to +125°C), PPAP documentation, and IATF 16949 manufacturing. This part is rated for industrial temperature range (-40°C to +85°C) only.
