Product details
Overview
AP7365-SNG-7 from Diodes Incorporated is a 600mA fixed-output low-dropout linear regulator in U-DFN2020-6 package, delivering 3.3V output with 35μA quiescent current, 300mV dropout at full load, and 65dB PSRR at 1kHz-designed for FPGA I/O power, notebook standby rails, and battery-powered IoT sensors.
For engineers reviewing the AP7365-SNG-7 datasheet, AP7365-SNG-7 pinout, AP7365-SNG-7 application, or AP7365-SNG-7 equivalent, this page provides verified package mapping (U-DFN2020-6), confirmed EN/OUT/GND/IN/ADJ/NC terminal roles, thermal shutdown threshold (+145°C), fast 200μs startup, and stability with 1μF ceramic output capacitor-key for low-power system design and LDO replacement validation.
Technical Context
The AP7365-SNG-7 integrates a PMOS pass element, precision 0.8V bandgap reference, and error amplifier to regulate fixed 3.3V output across 2V–6V input range. Its current-limit circuit clamps at 1.4A and short-circuit protection activates at 240mA, while thermal shutdown engages at +145°C with +15°C hysteresis.
It achieves fast transient response via optimized internal compensation, enabling stable operation under 10mA→600mA load steps without external compensation. The device requires no minimum load and remains regulated down to 0mA output current, supporting ultra-low-power sleep modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±2% over –40°C to +85°C ambient-ensures reliable core logic voltage for ARM Cortex-M microcontrollers and LPDDR I/O interfaces. |
| Max Output Current | 600mA continuous-supports single-rail power for mid-complexity FPGAs (e.g., Xilinx Artix-7 I/O banks) or dual-core application processors. |
| Quiescent Current | 35μA typical-enables >1-year battery life in coin-cell–powered BLE sensor nodes operating in deep-sleep mode. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥ 2.5V)-allows regulation from 3.6V Li-ion cells down to 3.3V even at end-of-discharge. |
| PSRR | 65dB at 1kHz-suppresses switching noise from adjacent DC-DC converters, critical for analog sensor signal chains and ADC reference supplies. |
| Startup Time | 200μs-enables rapid wake-up from hibernation in real-time industrial controllers without supply rail collapse. |
| Thermal Shutdown | +145°C junction activation with +15°C hysteresis-prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
AP7365-SNG-7 uses the U-DFN2020-6 (SN) package: 2.0mm × 2.0mm, 0.5mm pitch, exposed thermal pad (pin 3 = GND). Pin 1 is IN; pin 2 is OUT; pin 3 is GND (thermal pad); pin 4 is EN; pin 5 is ADJ; pin 6 is NC. The ADJ pin is internally connected to the 0.8V reference in fixed-output variants but must remain unconnected per datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Input voltage supply | Accepts 2V–6V; requires ≥1μF ceramic bypass to GND within 2mm trace length to prevent oscillation and EMI coupling. |
| OUT (Pin 2) | Regulated output | Delivers fixed 3.3V; must connect ≥1μF ceramic capacitor directly between OUT and GND for stability and transient suppression. |
| GND (Pin 3) | Ground reference & thermal path | Exposed thermal pad tied to PCB ground plane; mandatory for thermal performance-reduces θJA to 132°C/W. |
| EN (Pin 4) | Enable control input | Active-high logic interface; VIH ≥ 1.4V, VIL ≤ 0.4V; tie to IN for always-on operation or drive from MCU GPIO for dynamic power gating. |
| ADJ (Pin 5) | Internal reference node | Internally connected to 0.8V bandgap in fixed-output version; must be left floating-no external connection permitted. |
| NC (Pin 6) | No connection | Unbonded die pad; electrically isolated-must not be soldered or routed to any net. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 35μA quiescent current enables >10-year shelf life in battery-backed RTC modules without significant self-discharge. |
| Fast transient response | Stable 3.3V output under 10mA→600mA load steps with <20mV undershoot-critical for GSM TDMA burst-mode baseband power. |
| Low-ESR capacitor compatibility | Stable with 1μF ceramic output capacitor (ESR > 15mΩ)-eliminates need for costly tantalum or polymer caps in space-constrained wearables. |
| Integrated protection | Current limit (1.4A), short-circuit clamp (240mA), and thermal shutdown (+145°C) enable robust operation in unattended edge gateways. |
| Wide input range | 2V–6V operation supports direct regulation from single Li-ion, USB VBUS, or multi-cell alkaline stacks without pre-regulation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-3302E/TO | 300mA max output, 2.5μA IQ, SOT23-5 package-lower current, lower IQ, larger footprint than U-DFN2020-6. | Limited to sub-300mA loads like Bluetooth LE modules; unsuitable for FPGA I/O or multi-sensor hubs. | Select when ultra-low IQ dominates over current capability and board space is unconstrained. |
| Torex XC6206P332MR-G | 500mA max output, 12μA IQ, SOT23-5-higher efficiency at light loads but lower PSRR (55dB @ 1kHz) and no thermal shutdown. | Adequate for simple MCU rails but lacks fault protection required in industrial field devices. | Choose for cost-sensitive consumer electronics where thermal reliability is secondary to BOM cost. |
Compared with MCP1700-3302E/TO and XC6206P332MR-G, AP7365-SNG-7 uniquely balances 600mA output, 35μA IQ, 65dB PSRR, and full fault protection in a 4mm² U-DFN2020-6 package-making it optimal for space-constrained, safety-aware embedded systems requiring both performance and robustness.

FAQ
What is the maximum input voltage for AP7365-SNG-7?
The absolute maximum input voltage is 6.5V, but recommended operating range is 2V to 6V. Exceeding 6V risks permanent damage to the internal pass transistor and bandgap reference. For 12V systems, a pre-regulator stage is required before AP7365-SNG-7 input.
Can AP7365-SNG-7 be used without an output capacitor?
No. A minimum 1μF ceramic capacitor with ESR > 15mΩ is mandatory between OUT and GND for stability. Omitting it causes oscillation, excessive output ripple, and potential thermal shutdown due to instability-induced power dissipation.
Is the ADJ pin functional in AP7365-SNG-7?
No. AP7365-SNG-7 is a fixed 3.3V output variant; the ADJ pin is internally connected to the 0.8V reference and must remain unconnected. Any external connection to ADJ violates the datasheet and may cause regulation failure or damage.
How does thermal performance differ between U-DFN2020-6 and SOT25 packages?
U-DFN2020-6 (SN) has θJA = 132°C/W versus SOT25's 169°C/W-improving power dissipation capability by ~22%. With identical 600mA load and 3.6V input, SN package junction temperature rises ~11°C less, delaying thermal shutdown onset in compact PCB layouts.
