Product details
Overview
AP7365-08YG-13 from Diodes Incorporated is a fixed-output 0.8V, 600mA low-dropout linear regulator in SOT89 package with 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 AP7365-08YG-13 datasheet, AP7365-08YG-13 pinout, AP7365-08YG-13 application, or AP7365-08YG-13 equivalent, this page provides verified technical context, package-specific pin mapping, real-world application constraints, and validated alternative options for low-voltage, high-efficiency LDO selection.
Technical Context
The AP7365-08YG-13 implements a PMOS pass transistor architecture enabling 300mV dropout at 600mA output while maintaining 35μA quiescent current across 2V–6V input range. Its internal 0.8V bandgap reference and error amplifier deliver ±2% output accuracy over –40°C to +85°C ambient.
It integrates active-high EN control, thermal shutdown (145°C trip, 15°C hysteresis), current limit (~1.4A), and short-circuit protection (~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 ultra-low-voltage FPGA I/O and ASIC core rails. |
| Max Output Current | 600mA - sufficient for single-domain digital logic supply without external boost. |
| Dropout Voltage | 300mV at 600mA - enables operation from 1.1V input (e.g., single LiFePO₄ cell or buck-boost rail). |
| Quiescent Current | 35μA typical - extends battery life in always-on sensor nodes and wearable standby modes. |
| PSRR | 65dB at 1kHz - suppresses switching noise from upstream DC/DC converters feeding sensitive analog blocks. |
| Start-Up Time | 200μs - supports rapid wake-from-sleep sequences in real-time MCU applications. |
| Thermal Shutdown | 145°C with 15°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design. |
Pinout & Package
SOT89-3 (Y Package) with exposed thermal pad on pin 3 (IN); compact 4.5mm × 2.5mm footprint optimized for space-constrained portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated Output | Delivers stable 0.8V; requires 1μF ceramic capacitor placed adjacent to pin for stability and transient response. |
| 2 (GND) | Ground Reference | Primary return path for load current and internal bias; must connect directly to low-impedance ground plane. |
| 3 (IN) | Input Voltage Supply | Accepts 2V–6V; bypassed with ≥1μF MLCC close to pin to suppress input ripple and EMI. |
Key Features
| Feature | Design Value |
|---|---|
| Low Dropout Operation | 300mV @ 600mA enables use with sub-1.2V input sources like single-cell batteries or post-regulation rails. |
| Enable Control Interface | Active-high EN logic (VIH ≥ 1.4V) allows precise sequencing with MCU GPIO or system power manager. |
| Fast Transient Response | Stable under 10mA ↔ 600mA load steps without overshoot - critical for burst-mode DSP and RF SoC cores. |
| Thermal Protection | Auto-recovery shutdown at 145°C prevents latch-up during thermal stress; hysteresis avoids oscillation. |
| Green Compliance | Fully RoHS 3 compliant, halogen- and antimony-free - meets global environmental requirements for consumer and industrial products. |
Applications
| FPGA I/O Power | Wearable Sensor Node |

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 |
|---|---|---|---|
| MCP1703T-0802E/MB | 0.8V fixed, 250mA max, 12μA IQ, SOT23-5 package | Limited to lower current; better for sub-200mA logic rails but insufficient for FPGA I/O domains. | Select when board space is tighter and load current ≤250mA; avoid for 600mA peak loads. |
| Torex XC6210B082MR-G | 0.8V fixed, 300mA max, 1.2μA IQ, SOT25 package | Ultra-low IQ ideal for multi-year battery life, but half the current capability and no thermal shutdown. | Prefer for energy-harvesting or long-life IoT sensors; not suitable for thermally demanding or high-current applications. |
Compared with MCP1703T-0802E/MB and XC6210B082MR-G, the AP7365-08YG-13 uniquely balances 600mA drive, 35μA IQ, thermal protection, and SOT89 thermal performance-making it optimal for mid-power embedded systems requiring reliability and efficiency.

FAQ
What is the minimum input voltage required for stable 0.8V output at 600mA?
The AP7365-08YG-13 requires VIN ≥ 1.1V to maintain regulation at full load, based on its 300mV dropout specification. Below 1.1V input, output voltage collapses linearly; operation below 2.0V is outside recommended conditions per datasheet Section 5.
Can the EN pin be left floating, or must it be tied high?
The EN pin must never be left floating-it has no internal pull-up. For always-on operation, tie EN directly to IN. For controlled enable/disable, drive it with a clean logic signal meeting VIH ≥ 1.4V and VIL ≤ 0.4V, with source/sink capability ≥1μA.
Is the SOT89 package thermally adequate for continuous 600mA operation at 85°C ambient?
Yes, with proper PCB layout: use ≥1cm² copper pour connected to pin 3 (IN) thermal pad, 2oz copper, and thermal vias. At TA = 85°C, θJA = 133°C/W yields ~10.5W power dissipation margin before reaching 145°C junction limit under worst-case (VIN = 6V, VOUT = 0.8V).
Does the 0.8V output version support adjustable configuration via external resistors?
No-the AP7365-08YG-13 is a fixed-output variant. Adjustable versions (e.g., AP7365-ADJ) exist only in SOT25 and U-DFN2020-6 packages and require ADJ pin connection to resistor divider; this SOT89 part lacks ADJ functionality and has no feedback pin.
