Product details
Overview
AP7365-15ERG-13 from Diodes Incorporated is a fixed-output 1.5V, 600mA low-dropout linear regulator with 35μA quiescent current, 300mV dropout at full load, and integrated enable control. It operates from 2V–6V input, delivers ±2% output accuracy across –40°C to +85°C, and supports fast 200μs startup for battery-powered FPGA I/O and DSP core rails.
For engineers reviewing the AP7365-15ERG-13 datasheet, AP7365-15ERG-13 pinout, AP7365-15ERG-13 application, or AP7365-15ERG-13 equivalent, key selection criteria include dropout voltage under 600mA load, thermal shutdown threshold at +145°C, PSRR of 65dB at 1kHz, and compatibility with 1μF ceramic output capacitors in SOT223-ER package.
Technical Context
The AP7365-15ERG-13 implements a PMOS pass transistor architecture enabling low dropout (300mV @ 600mA) and high PSRR (65dB @ 1kHz). Its internal 0.8V bandgap reference and error amplifier regulate output precisely without external components for fixed-voltage operation.
Enable logic (VIH = 1.4V, VIL = 0.4V) controls output state independently of input voltage, while built-in current limit (~1.4A), short-circuit protection (~240mA), and thermal shutdown (+145°C trip, +130°C hysteresis) ensure fault resilience in embedded power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5V ±2% over –40°C to +85°C; enables direct powering of low-voltage I/O domains without resistor divider. |
| Max Output Current | 600mA continuous; sufficient for FPGA auxiliary rails and DSP memory interfaces with margin for transient peaks. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥ 2.5V); allows stable 1.5V output from 1.8V input sources like single-cell LiFePO₄ batteries. |
| Quiescent Current | 35μA typical; minimizes standby power loss in always-on subsystems such as real-time clocks or sensor hubs. |
| PSRR | 65dB at 1kHz; suppresses switching noise from upstream DC-DC converters feeding mixed-signal SoCs. |
| Startup Time | 200μs typical; supports rapid wake-up from deep sleep in portable devices without output overshoot. |
| Thermal Shutdown | +145°C junction trip 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 = IN, pin 1 = GND, pin 2 = OUT); optimized for thermal dissipation in space-constrained industrial PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 3) | Input voltage supply | Accepts 2V–6V; requires ≥1μF ceramic bypass capacitor placed adjacent to pin for EMI suppression and stability. |
| GND (Pin 1) | Power ground reference | Common return path for input/output currents; must connect directly to low-impedance ground plane beneath thermal pad. |
| OUT (Pin 2) | Regulated output | Delivers 1.5V ±2%; stable with 1μF ceramic capacitor (ESR > 15mΩ); output trace must minimize inductance. |
| EN (Not present) | Enable control input | Not implemented in ER-package fixed-output variant; device operates continuously when powered. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout operation | 300mV at 600mA enables use with 1.8V input sources, extending battery runtime in portable instrumentation. |
| Ultra-low quiescent current | 35μA typical ensures <1μW standby power loss per regulator, critical for multi-rail always-on sensor nodes. |
| Fast transient response | Stable under 10mA→600mA load steps with <20mV undershoot/overshoot; maintains clean supply for high-speed ADCs. |
| Integrated protection | Current limit (~1.4A), short-circuit clamp (~240mA), and thermal shutdown prevent field failures in unattended systems. |
| Small-footprint packaging | SOT223-ER offers 3.5×3.5mm footprint with thermal pad; achieves 142°C/W θJA on standard FR-4, simplifying thermal design. |

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 |
|---|---|---|---|
| AP7365-15W-7 | SOT25 package (θJA = 169°C/W); no thermal pad; higher thermal resistance limits max continuous current to ~400mA at TA = 85°C. | Suitable for space-constrained consumer PCBs where thermal mass is limited but peak power is moderate. | Select when board area is prioritized over thermal performance and load current remains below 400mA. |
| AP7365-15SNG-7 | U-DFN2020-6 package (θJA = 132°C/W); 2.0×2.0mm footprint; requires solder paste stencil optimization for thermal pad reflow. | Ideal for ultra-dense portable electronics (e.g., wearables) needing minimal footprint and better thermal performance than SOT25. | Select when PCB real estate is critical and assembly process supports fine-pitch DFN reflow profiles. |
Compared with AP7365-15W-7 and AP7365-15SNG-7, the AP7365-15ERG-13 provides superior thermal management (θJA = 142°C/W) and mechanical robustness in SOT223-ER, making it optimal for industrial designs requiring sustained 600mA delivery in elevated ambient temperatures.

FAQ
Is AP7365-15ERG-13 compatible with 1μF ceramic output capacitors?
Yes. The AP7365-15ERG-13 is explicitly characterized for stability with 1μF ceramic capacitors having ESR > 15mΩ. This eliminates need for larger or higher-ESR electrolytic capacitors, reducing board area and cost while improving transient response.
What is the maximum ambient temperature for continuous 600mA operation in SOT223-ER package?
At TA = +85°C, the AP7365-15ERG-13 can sustain 600mA output with VIN = 3.0V (1.5V dropout) assuming standard FR-4 PCB layout with minimum recommended copper pour on the thermal pad. Derating is required above this condition per θJA = 142°C/W and TJ(max) = +150°C.
Does AP7365-15ERG-13 include an enable pin?
No. The ER suffix denotes the SOT223 fixed-output variant without EN functionality. The device powers up automatically when input voltage exceeds 2V. For enable-controlled operation, select AP7365-15WG-7 (SOT25) or AP7365-15SNG-7 (U-DFN2020-6).
How does the 300mV dropout specification apply to 1.5V output?
The 300mV dropout applies to VOUT ≥ 2.5V per datasheet Note 5. For 1.5V output, dropout is 370mV (typical) at 600mA. Thus, minimum input is 1.87V to maintain regulation - verified by electrical characteristics table entry for VDROPOUT at VOUT < 2.5V.
