Product details
Overview
AP7365-08SNG-7 from Diodes Incorporated is a fixed-output 0.8V, 600mA low-dropout linear regulator in U-DFN2020-6 package, featuring 35μA quiescent current, 300mV dropout at full load, and integrated enable control. It delivers stable core voltage for FPGA I/O rails and battery-powered microcontrollers where ultra-low standby power and fast transient response are critical.
For engineers reviewing the AP7365-08SNG-7 datasheet, AP7365-08SNG-7 pinout, AP7365-08SNG-7 application, or AP7365-08SNG-7 equivalent, this page provides verified technical context, package-specific pin mapping, real-world application constraints, and validated alternative options for low-voltage LDO selection.
Technical Context
The AP7365-08SNG-7 implements a PMOS pass transistor architecture with internal 0.8V bandgap reference, enabling fixed 0.8V output without external feedback resistors. Its EN pin accepts logic-high signals ≥1.4V to activate regulation and supports direct tie-to-IN for always-on operation.
Thermal shutdown triggers at +145°C with +15°C hysteresis, while current limit clamps output to 1.4A during overload and short-circuit protection limits fault current to 240mA. PSRR reaches 65dB at 1kHz, and start-up time is 200μs with 1μF ceramic output capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 0.8V ±2% - matches modern FPGA core and ASIC I/O supply requirements |
| Max Output Current | 600mA - sufficient for single-core processors or multi-rail I/O banks |
| Quiescent Current | 35μA typical - enables >1-year battery life in always-on sensor nodes |
| Dropout Voltage | 300mV at 600mA - allows operation from 1.1V input (e.g., single LiFePO₄ cell) |
| PSRR | 65dB at 1kHz - suppresses switching noise from adjacent DC/DC converters |
| Start-Up Time | 200μs - supports rapid wake-from-sleep in portable devices |
| Operating Temp | −40°C to +85°C - qualified for industrial and automotive cabin applications |
Pinout & Package
AP7365-08SNG-7 uses the U-DFN2020-6 (SN) package with wettable flank leads and exposed thermal pad (GND-connected). The 2.0mm × 2.0mm footprint supports high-density PCB layouts and efficient heat dissipation via soldered thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 3) | Input voltage supply | Accepts 2V–6V; requires ≥1μF MLCC decoupling directly at pin |
| GND (Pin 2) | Ground reference and thermal path | Connected to exposed thermal pad; must be solid copper pour for thermal management |
| EN (Pin 1) | Enable control input | Active-high logic; ≥1.4V required to turn on regulator; tie to IN for permanent enable |
| OUT (Pin 4) | Regulated output | Delivers fixed 0.8V; bypassed with ≥1μF ceramic capacitor near pin |
| ADJ (Pin 6) | Reference feedback node | No connection in fixed-output version; left floating or grounded per design |
| NC (Pin 5) | No connection | Internally unconnected; must not be tied to any net |
Key Features
| Feature | Design Value |
|---|---|
| Low IQ with full-load capability | 35μA quiescent current maintained across 2V–6V input range and 0–600mA load |
| Stability with minimal capacitance | Guaranteed stable using only 1μF ceramic output capacitor (ESR ≥15mΩ) |
| Fast transient recovery | Load step from 10mA to 600mA induces <200mV undershoot/overshoot at 3.3V output |
| Integrated fault protection | Simultaneous thermal shutdown (+145°C), current limit (1.4A), and short-circuit clamp (240mA) |
| Green packaging compliance | Totally lead-free, halogen- and antimony-free per Diodes' "Green" definition (<900ppm Br/Cl) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-voltage LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP7361-08SNG-7 | 300mA max output, identical 0.8V fixed output and U-DFN2020-6 package | Lower current capacity suits RTC or sensor bias rails, not processor cores | Select when load ≤300mA and board space must match AP7365-08SNG-7 footprint |
| MCP1804-0802E/MB | 600mA output but 50μA IQ, SOT-23-5 package, no EN pin | Lacks enable control and has higher quiescent current; different pinout and thermal performance | Choose only if EN functionality is unnecessary and SOT-23 layout compatibility is mandatory |
Compared with AP7365-08SNG-7, AP7361-08SNG-7 reduces cost and thermal load for sub-300mA loads, while MCP1804-0802E/MB trades enable control and ultra-low IQ for legacy package compatibility-neither offers identical combination of 0.8V/600mA/35μA/EN/U-DFN2020-6.

FAQ
What is the minimum input voltage required for AP7365-08SNG-7 to maintain 0.8V output at 600mA?
The device requires VIN ≥ 1.1V to sustain regulation at full load, based on its 300mV dropout specification (0.8V + 0.3V = 1.1V). Operation below 1.1V results in unregulated output, and absolute minimum VIN is 2.0V per recommended operating conditions-so 1.1V is functional but outside datasheet guarantee. Input must remain ≥2.0V for guaranteed performance.
Can AP7365-08SNG-7 operate without an output capacitor?
No. The datasheet mandates a minimum 1μF ceramic output capacitor with ESR ≥15mΩ for stability. Omitting it causes oscillation and voltage overshoot during load transients. Larger capacitors improve transient response but do not replace the fundamental 1μF requirement. Placement within 2mm of OUT/GND pins is critical.
Is the ADJ pin used in the fixed-output AP7365-08SNG-7?
No. In fixed-output versions like AP7365-08SNG-7, the ADJ pin (Pin 6) is internally connected to the 0.8V reference and must be left floating or grounded-never tied to external circuitry. Using it as a feedback node would disrupt regulation. Pin 6 serves only for adjustable variants (e.g., AP7365-SNG-7).
How does thermal shutdown behave under continuous overload?
When junction temperature reaches +145°C, the device disables output and enters thermal shutdown. It remains off until temperature drops to +130°C (15°C hysteresis), then re-enables. Under sustained overload, this causes cycling-visible as intermittent output voltage collapse-protecting the IC but indicating inadequate heatsinking or excessive power dissipation.
