Product details
Overview
AP7365-08ERG-13 from Diodes Incorporated is a 600mA fixed-output (0.8V) low-dropout linear regulator in SOT223-ER 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 AP7365-08ERG-13 datasheet, AP7365-08ERG-13 pinout, AP7365-08ERG-13 application, or AP7365-08ERG-13 equivalent, key selection criteria include output voltage accuracy (±2%), fast 200μs startup, PSRR of 65dB at 1kHz, stability with 1μF ceramic output capacitor, and thermal shutdown threshold at +145°C.
Technical Context
The AP7365-08ERG-13 implements a PMOS pass transistor architecture enabling low dropout (300mV @ 600mA, VOUT ≥ 2.5V; 370mV typical for 0.8V output) and ultra-low quiescent current (35μA typ). Its internal 0.8V bandgap reference and error amplifier deliver tight output regulation across -40°C to +85°C ambient.
Enable logic operates with VIH ≥ 1.4V and VIL ≤ 0.4V, supporting direct connection to 1.8V/3.3V GPIO. Protection circuitry includes foldback current limiting (1.4A typ), short-circuit clamping (240mA), and thermal shutdown with 15°C hysteresis-ensuring robust operation under fault conditions without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 0.8V ±2% over -40°C to +85°C - matches ultra-low-voltage FPGA core and ASIC I/O rails. |
| Max Output Current | 600mA continuous - supports high-efficiency point-of-load regulation for digital logic cores. |
| Dropout Voltage | 300mV @ 600mA (VOUT ≥ 2.5V); 370mV typ @ 600mA for 0.8V output - enables operation from 1.1V input in deep-sleep systems. |
| Quiescent Current | 35μA typical, 80μA max - extends battery life in always-on sensor nodes and wearables. |
| PSRR | 65dB @ 1kHz - suppresses switching noise from adjacent DC-DC converters feeding mixed-signal SoCs. |
| Start-Up Time | 200μs typical - meets real-time wake-up requirements for low-power MCU sleep-to-active transitions. |
| Thermal Shutdown | Triggers at +145°C junction temperature with +15°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
SOT223-ER package with exposed thermal pad (pin 3 = GND, pin 2 = OUT, pin 1 = IN); thermally enhanced layout supports up to 142°C/W junction-to-ambient resistance on standard FR-4 board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Input voltage supply | Accepts 2V–6V input; requires ≥1μF ceramic bypass capacitor placed adjacent to pin for noise suppression and stability. |
| OUT (Pin 2) | Regulated output | Delivers stable 0.8V; connects directly to load; requires ≥1μF ceramic capacitor with ESR >15mΩ for guaranteed stability. |
| GND (Pin 3, TAB) | Power ground / thermal pad | Primary return path and main thermal conduction path; must be soldered to large copper pour for thermal management. |
| EN (Pin ?) | Enable control input | Active-high logic input (VIH ≥ 1.4V); tied internally to IN if unused; controls regulator ON/OFF state with <1μA leakage. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ operation | 35μA typical quiescent current enables >1-year battery life in coin-cell-powered edge sensors. |
| Fast transient response | Stable under 10mA ↔ 600mA load steps with <200mV undershoot - critical for GSM/TDMA burst-mode baseband power. |
| Single-capacitor stability | Guaranteed stable with only 1μF ceramic output capacitor - reduces BOM count and PCB area vs. legacy LDOs requiring 10–22μF tantalum. |
| Integrated protection | Current limit (1.4A), short-circuit clamp (240mA), and thermal shutdown (+145°C) eliminate need for external fault management circuitry. |
| Wide input range | Operates from 2V to 6V - compatible with single Li-ion, dual alkaline, or post-regulated DC-DC outputs. |

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 | Same 0.8V output but SOT25 package; lower thermal performance (θJA = 169°C/W vs. 142°C/W); 300mA max output. | Limited to space-constrained, lower-power designs where PCB thermal relief is impractical. | Select when footprint size is prioritized over thermal headroom and current capability. |
| MCP1700-0802E/TO | 0.8V fixed output, 250mA rating, 1.6μA IQ - significantly lower quiescent current but no enable pin or thermal shutdown. | Suitable only for ultra-low-power always-on functions without dynamic load or fault protection needs. | Choose only for sub-100mA applications where zero-load IQ dominates design priority and protection is handled externally. |
Compared with AP7365-08ERG-13, AP7361-08WG-7 trades thermal robustness and current capacity for smaller footprint, while MCP1700-0802E/TO sacrifices protection features and load capability to achieve nanoamp-level standby current-making AP7365-08ERG-13 the balanced choice for protected, medium-current 0.8V regulation in thermally demanding environments.

FAQ
What is the minimum input voltage required for AP7365-08ERG-13 to regulate 0.8V output at 600mA?
The device requires VIN ≥ VOUT + VDROPOUT = 0.8V + 0.37V = 1.17V minimum; however, the absolute minimum specified input is 2.0V per datasheet operating conditions. Below 2.0V, PSRR degrades and startup time increases-so 2.0V is the practical minimum for guaranteed performance.
Can AP7365-08ERG-13 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 unregulated output. The capacitor must be placed adjacent to OUT and GND pins using short, low-inductance traces.
Is the EN pin 5V-tolerant when used with a 3.3V microcontroller GPIO?
Yes. The EN pin accepts VIH ≥ 1.4V and tolerates voltages up to VIN + 0.3V (max 6.8V). When VIN = 6V, EN can safely accept 3.3V GPIO signals without level shifting-no external resistor divider needed.
How does thermal shutdown behave under continuous overload at +70°C ambient?
At +70°C ambient and 600mA load with VIN = 3.3V, power dissipation is ~1.5W. With θJA = 142°C/W, junction temperature rises ~213°C above ambient-triggering thermal shutdown at +145°C. The device cycles on/off with ~15°C hysteresis, limiting average power to safe levels without damage.
