Product details
Overview
AP7366EA-SN-7 from Diodes Incorporated is a 600mA adjustable/fixed-output low-dropout linear regulator in U-DFN2020-6 package, featuring 60μA quiescent current, 300mV dropout at 600mA (VOUT=3.3V), 75dB PSRR at 1kHz, and integrated enable, current limit, and thermal shutdown. It powers FPGA I/O rails and battery-powered portable devices requiring stable low-noise voltage regulation.
For engineers reviewing the AP7366EA-SN-7 datasheet, AP7366EA-SN-7 pinout, AP7366EA-SN-7 application, or AP7366EA-SN-7 equivalent, key selection criteria include dropout voltage at full load, EN logic thresholds (VIH=1.0V, VIL=0.3V), thermal resistance (θJA=46.2°C/W), output capacitor stability with 1μF ceramic, and fixed-output voltage options including 3.3V.
Technical Context
The AP7366EA-SN-7 implements a PMOS pass transistor architecture enabling ultra-low dropout and fast transient response. Its internal 0.8V bandgap reference feeds an error amplifier that regulates output via external resistor divider (adjustable) or internal feedback network (fixed).
Enable control uses active-high logic with 3MΩ internal pull-down; thermal shutdown activates at +150°C with +20°C hysteresis. Protection includes foldback current limiting (typ. 1.0A) and short-circuit clamping to 250mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 600mA max - supports FPGA core/I/O power domains without derating at +85°C ambient. |
| Quiescent Current | 60μA typical - enables >1-year battery life in always-on IoT sensors with 200mAh coin cell. |
| Dropout Voltage | 300mV at 600mA (VOUT=3.3V) - allows operation from single-cell Li-ion (3.0V min) while maintaining regulation. |
| PSRR | 75dB at 1kHz - suppresses switching noise from adjacent DC/DC converters feeding mixed-signal SoCs. |
| Start-up Time | 150μs - enables rapid power sequencing in multi-rail systems with tight timing budgets. |
| Thermal Resistance | θJA = 46.2°C/W (U-DFN2020-6) - permits 450mW dissipation before thermal shutdown at +85°C ambient. |
| Input Voltage Range | 2.2V to 6.0V - compatible with USB-powered peripherals, Li-ion, and 3.3V/5V system rails. |
| Output Accuracy | ±1% for VOUT ≥1.5V - ensures reliable operation of 1.8V/2.5V/3.3V digital interfaces without margining. |
Pinout & Package
AP7366EA-SN-7 is housed in a 2.0mm × 2.0mm × 0.6mm U-DFN2020-6 package with wettable flank leads and exposed thermal pad (pin 2). The package supports reflow soldering per J-STD-020 Level 1 and delivers 46.2°C/W junction-to-ambient thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 3) | Input voltage supply | Accepts 2.2–6.0V; requires ≥1μF MLCC decoupling placed adjacent to pin for EMI suppression. |
| GND (Pin 2) | Power ground reference | Connects to PCB thermal pad for heat dissipation; must be low-impedance plane for stability. |
| EN (Pin 1) | Enable control input | Active-high logic (VIH ≥1.0V); internal 3MΩ pull-down ensures default-off state if left floating. |
| ADJ (Pin 6) | Feedback reference node | Connects to resistor divider (R1/R2) for adjustable outputs; max R2 = 80kΩ to maintain reference accuracy. |
| OUT (Pin 4) | Regulated output | Delivers up to 600mA; stable with ≥1μF ceramic capacitor; output discharge resistor (100Ω) aids fast turn-off. |
| NC (Pins 5 & ?) | No-connect terminal | Pins 5 and 6 are NC in fixed-output configuration; leaving unconnected has no functional impact. |
Key Features
| Feature | Design Value |
|---|---|
| Low-IQ operation | 60μA quiescent current enables micropower sleep modes in wearables and sensor nodes. |
| Fast transient response | Load step recovery within 200μs (50mA→500mA) minimizes voltage droop on processor I/O rails. |
| Stability with small capacitors | Guaranteed stability using only 1μF ceramic output capacitor reduces BOM cost and board area. |
| Integrated protection | Current limit (1.0A typ), short-circuit clamp (250mA), and thermal shutdown (+150°C) eliminate need for external fault management. |
| Wide output flexibility | Fixed 3.3V output (per -SN-7 suffix) or adjustable 0.8–5.0V via external resistors supports diverse SoC voltage requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-3302E/MB | 300mA output, 2.0μA IQ, SOT-23-5 package, 600mV dropout at 250mA | Limited to 300mA; insufficient for FPGA I/O or USB PHY loads requiring 600mA | Select only for ultra-low-power sensor nodes where 300mA headroom is acceptable. |
| Torex XC6210B332MR-G | 500mA output, 1.0μA IQ, SOT-25 package, 200mV dropout at 300mA | Lower dropout but 100mA less output current; no EN pin or thermal shutdown | Use where minimal IQ dominates design priority and fault protection is handled externally. |

FAQ
What is the minimum output capacitor required for stability?
The AP7366EA-SN-7 is guaranteed stable with a single 1μF X5R/X7R ceramic capacitor on the output. Larger values improve transient response but are not required for basic regulation. Avoid high-ESR electrolytic or tantalum capacitors unless compensated per datasheet guidelines.
Can the AP7366EA-SN-7 be used in adjustable mode?
No-the -SN-7 suffix denotes the fixed 3.3V output version in U-DFN2020-6 package. Adjustable versions use different part numbers (e.g., AP7366EA-ADJSN-7) with ADJ pin functional and internal feedback disabled. Pin 6 (ADJ) is no-connect in this variant.
How does the EN pin behave during power-up?
The EN pin has an internal 3MΩ pull-down resistor, ensuring the device remains off until a valid logic-high signal (≥1.0V) is applied. This prevents unintended turn-on during system reset or brown-out conditions, eliminating need for external pull-down components.
What thermal derating applies above +85°C ambient?
With θJA = 46.2°C/W, maximum allowable power dissipation drops linearly above +85°C. At +100°C ambient, PDmax = (150°C − 100°C) / 46.2°C/W ≈ 1.08W. For VIN=5.0V, VOUT=3.3V, this limits continuous output current to ~635mA-within rated 600mA, so no derating needed up to +100°C.
