Product details
Overview
AP7365-08WG-7 from Diodes Incorporated is a fixed-output 0.8V, 600mA low-dropout linear regulator in SOT25 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 AP7365-08WG-7 datasheet, AP7365-08WG-7 pinout, AP7365-08WG-7 application, or AP7365-08WG-7 equivalent, key selection criteria include output accuracy (±2%), thermal shutdown threshold (+145°C), PSRR (65dB @1kHz), and compatibility with 1μF ceramic output capacitors without minimum load requirements.
Technical Context
The AP7365-08WG-7 implements a PMOS pass transistor architecture enabling low dropout (300mV @600mA) and high PSRR (65dB @1kHz) across 2V–6V input range. Its internal 0.8V bandgap reference and error amplifier support tight output regulation (±2% over –40°C to +85°C) without external compensation.
Enable logic operates with VIH ≥1.4V and VIL ≤0.4V, allowing direct interfacing with 1.8V/3.3V GPIOs. Built-in current limit (1.4A typical) and short-circuit protection (240mA) operate independently of external components, while thermal shutdown activates at +145°C with +15°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 0.8V ±2% - matches modern ultra-low-voltage FPGA I/O and ASIC core rails. |
| Max Output Current | 600mA continuous - sufficient for multi-rail digital subsystems with burst loads. |
| Quiescent Current | 35μA typical - enables >1-year battery life in always-on sensor nodes. |
| Dropout Voltage | 300mV @600mA - supports operation down to VIN = 1.1V, critical for single-cell Li-ion systems. |
| PSRR | 65dB @1kHz - suppresses switching noise from adjacent DC-DC converters feeding mixed-signal circuits. |
| Start-Up Time | 200μs - enables rapid wake-up from deep sleep in portable devices without voltage droop. |
| Thermal Shutdown | +145°C activation - protects against sustained overload in compact PCB layouts with limited copper area. |
Pinout & Package
SOT25 (W package) - 5-pin surface-mount package with exposed thermal pad on bottom (not electrically connected). Pin 1 (IN) and Pin 5 (OUT) require wide copper traces; Pin 2 (GND) must connect directly to solid ground plane for thermal and noise performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Bypassed to GND with ≥1μF MLCC; minimum trace width 0.5mm to limit IR drop under 600mA. |
| 2 (GND) | Power ground reference | Primary thermal path; requires direct connection to inner-layer ground plane via ≥4 vias. |
| 3 (EN) | Enable control input | Active-high logic interface; ties to IN if always-on operation required. |
| 4 (NC) | No connection | Unbonded die pad; must remain floating-no PCB trace or copper pour. |
| 5 (OUT) | Regulated output | Stabilized by 1μF ceramic capacitor placed within 2mm of pin; ESR >15mΩ ensures stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ operation | 35μA enables >10-year shelf life in coin-cell–powered IoT endpoints. |
| Fast transient response | Stable under 0→600mA load steps without external compensation-critical for GSM/TDMA baseband power. |
| Single-capacitor stability | Works with 1μF ceramic output cap (ESR ≥15mΩ); eliminates need for costly tantalum or polymer alternatives. |
| Integrated protection | Current limit (1.4A), short-circuit clamp (240mA), and thermal shutdown (+145°C) prevent field failures without external circuitry. |
| Wide input range | 2V–6V operation supports single-cell Li-ion (2.7–4.2V), USB (4.75–5.25V), and industrial 5V rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP7361-08WG-7 | 300mA max output, identical 0.8V fixed output and 35μA IQ, same SOT25 package. | Lower current capacity limits use to sub-300mA logic rails or sensor biasing-not suitable for FPGA I/O or GSM bursts. | Select when load current never exceeds 300mA and board space must match AP7365 footprint. |
| MCP1700T-0802E/TT | 250mA output, 1.6μA IQ, 6V max input, SOT23-5 package; no enable pin. | Lacks EN control and thermal shutdown; unsuitable for automotive or industrial environments requiring fault protection. | Choose only for ultra-low-power always-on sensors where 250mA suffices and enable functionality is unnecessary. |
Compared with AP7361-08WG-7, the AP7365-08WG-7 provides double the output current and integrated thermal/current protection-essential for FPGA and GSM applications. Versus MCP1700T-0802E/TT, it trades 33× higher IQ for robustness, enable control, and 2.4× higher current, making it appropriate for mission-critical embedded systems.

FAQ
What is the minimum input voltage required for stable 0.8V output at 600mA?
The AP7365-08WG-7 requires VIN ≥ 1.1V to maintain regulation at 600mA, based on its 300mV dropout specification. At lower input voltages, output collapses proportionally; operation below VIN = 1.1V is outside recommended conditions and may trigger thermal shutdown due to excessive power dissipation.
Can the EN pin be left unconnected, or must it be tied high?
The EN pin must not be left floating-it must be actively driven or hard-wired. For always-on operation, tie EN directly to IN. Leaving it open risks undefined state due to leakage currents, potentially causing intermittent startup or latch-up in noisy environments.
Is a minimum load required to ensure stability with a 1μF ceramic output capacitor?
No minimum load is required. The AP7365-08WG-7 remains stable and regulated from zero load to full 600mA with a 1μF ceramic capacitor (ESR ≥15mΩ), as confirmed in the datasheet's "No Load Stability" section and validated across –40°C to +85°C.
How does thermal performance differ between SOT25 and U-DFN2020-6 packages at 600mA?
In SOT25 (θJA = 169°C/W), power dissipation of 180mW at 600mA causes ~30°C rise above ambient; in U-DFN2020-6 (θJA = 132°C/W), the same dissipation yields ~24°C rise. Both stay well below thermal shutdown threshold (+145°C) with standard 1oz copper PCB layout.
