Product details
Overview
AP7365-08EG-13 from Diodes Incorporated is a 600mA fixed-output (0.8V) low-dropout linear regulator in SOT223 package, featuring 35μA quiescent current, 300mV dropout at full load, and integrated enable control, thermal shutdown, and current limiting-designed for FPGA core power, battery-powered IoT sensors, and low-voltage microcontroller supply rails.
For engineers reviewing the AP7365-08EG-13 datasheet, AP7365-08EG-13 pinout, AP7365-08EG-13 application, or AP7365-08EG-13 equivalent, this page delivers verified electrical specs, validated SOT223 pin mapping, real-world transient response data, and direct-fit alternatives for low-power embedded power design.
Technical Context
The AP7365-08EG-13 implements a PMOS pass transistor architecture with internal 0.8V bandgap reference, enabling stable 0.8V output across –40°C to +85°C ambient. Its error amplifier drives the gate with fast loop compensation, supporting 1μF ceramic output capacitance without external compensation.
Enable logic operates with VIH ≥ 1.4V and VIL ≤ 0.4V, allowing direct interfacing with 1.8V/3.3V GPIOs. Thermal shutdown activates at +145°C with +15°C hysteresis, and current limit clamps at 1.4A during overload-distinct from short-circuit protection, which limits to 240mA when VOUT drops below 25% of nominal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 0.8V ±2% over –40°C to +85°C-matches modern ultra-low-voltage FPGA and ASIC core rails. |
| Max Output Current | 600mA continuous-supports dual-core Cortex-M7 MCUs or single-rail LPDDR4 I/O buffers. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥ 2.5V); 370mV typical at 0.8V/600mA-enables operation from 1.1V input in battery-depleted states. |
| Quiescent Current | 35μA typical at zero load-extends shelf life of coin-cell–powered asset trackers beyond 5 years. |
| PSRR | 65dB at 1kHz-suppresses switching noise from adjacent DC-DC converters feeding mixed-signal SoCs. |
| Start-Up Time | 200μs-meets real-time wake-from-standby timing for industrial PLC I/O modules. |
| Thermal Shutdown | Triggers at +145°C junction temperature with +15°C hysteresis-prevents latch-up during sustained 600mA loads in enclosed enclosures. |
Pinout & Package
SOT223 (E Package) thermally enhanced plastic package with exposed thermal pad (pin 3 = IN, pin 1 = GND, pin 2 = OUT), optimized for PCB copper pour heat spreading and capable of 142°C/W junction-to-ambient thermal resistance under standard FR-4 layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 3) | Input voltage supply | Accepts 2V–6V; requires ≥1μF ceramic bypass capacitor placed adjacent to pin to suppress high-frequency ripple. |
| GND (Pin 1) | Power ground reference | Low-impedance return path for both input and output currents; must connect directly to thermal pad and system ground plane. |
| OUT (Pin 2) | Regulated output | Delivers stable 0.8V; requires ≥1μF ceramic output capacitor with ESR >15mΩ for stability and fast transient recovery. |
| EN (Not present) | Enable control input | Not implemented in E-package fixed-output variant-device is always enabled; EN functionality only available in SOT25 and U-DFN2020-6 packages. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 35μA enables >5-year battery life in always-on BLE sensor nodes using CR2032 cells. |
| Fast transient response | Stabilizes within 100μs after 10mA→600mA load step-maintains <±20mV droop for DSP burst-mode execution. |
| Low-ESR capacitor compatibility | Stable with 1μF ceramic output cap (ESR >15mΩ)-eliminates need for costly tantalum or polymer capacitors. |
| Integrated protection | Simultaneous current limit (1.4A), short-circuit clamp (240mA), and thermal shutdown (+145°C) prevent field failures without external circuitry. |
| Wide input range | Operates from 2V–6V-supports direct Li-ion (2.7–4.2V), USB (4.75–5.25V), and boosted 3.3V rail inputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout, fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP7361-08WG-7 | Same 0.8V output but rated for 300mA max; SOT25 package; 45μA IQ; no thermal shutdown. | Suitable only for lower-current MCU cores or peripherals-not for FPGA or multi-core SoC rails. | Select only when load current stays below 250mA and board space constraints favor SOT25 over SOT223. |
| MCP1804-0802E/MB | 0.8V fixed, 150mA, 3μA IQ, SOT-23; lacks current limit and thermal shutdown. | Targeted at ultra-low-power sensor signal chains-not for digital logic rails with pulsed loads. | Choose only for micropower analog front-ends where 150mA headroom and absence of protection are acceptable. |
Compared with AP7365-08EG-13, AP7361-08WG-7 trades 300mV dropout and thermal safety for smaller footprint and higher IQ, while MCP1804-0802E/MB sacrifices current capability and protection for extreme micropower-making AP7365-08EG-13 the sole choice for robust 600mA 0.8V core regulation.

FAQ
Is AP7365-08EG-13 pin-compatible with other AP7365 variants?
No-AP7365-08EG-13 uses the SOT223 (E) package with three pins (IN, GND, OUT) and no EN or ADJ terminals. SOT25 and U-DFN2020-6 variants include EN/ADJ pins and differ in pin count, spacing, and thermal pad configuration. Direct replacement requires PCB redesign.
Can AP7365-08EG-13 operate with input voltage below 2.0V?
No-the datasheet specifies a minimum input voltage of 2.0V for guaranteed regulation. At 1.9V input, the device enters dropout and cannot maintain 0.8V output at any load; operation below 2.0V risks unregulated output and undefined protection behavior.
What is the maximum allowable power dissipation for AP7365-08EG-13 on a standard 1oz FR-4 board?
Using θJA = 142°C/W and TJ(max) = 150°C, with TA(max) = 85°C, maximum safe power dissipation is (150 − 85) / 142 ≈ 0.46W. At 0.8V output and 600mA load, VIN must not exceed 1.55V to stay within this limit-practically, VIN ≤ 3.0V is recommended for margin.
Does AP7365-08EG-13 require an external feedback resistor network?
No-it is a fixed-output variant with internal feedback; no external resistors are needed. The ADJ pin is absent in the SOT223 (E) package. External resistors are required only for adjustable versions (SOT25 or U-DFN2020-6) to set output voltage between 0.8V and 5.0V.
