Product details
Overview
AP7365-30EG-13 from Diodes Incorporated is a fixed-output 3.0V, 600mA low-dropout linear regulator with enable control, 35μA quiescent current, and 300mV dropout at full load. It integrates current limit, thermal shutdown, and fast 200μs startup for battery-powered FPGA I/O and DSP core power rails in portable electronics.
For engineers reviewing the AP7365-30EG-13 datasheet, AP7365-30EG-13 pinout, AP7365-30EG-13 application, or AP7365-30EG-13 equivalent, key selection criteria include dropout voltage at 600mA, PSRR at 1kHz, EN logic thresholds, thermal resistance in SOT223-E package, and stability with 1μF ceramic output capacitor.
Technical Context
The AP7365-30EG-13 uses a PMOS pass element with internal 0.8V bandgap reference and error amplifier to regulate fixed 3.0V output across input voltages from 2V to 6V. Its architecture enables low dropout (300mV @ 600mA) and ultra-low IQ (35μA typ) without compromising transient response.
Enable functionality is implemented via active-high EN pin with VIH ≥1.4V and VIL ≤0.4V, directly compatible with 1.8V/3.3V logic. Protection circuitry includes foldback current limiting (1.4A typ), short-circuit clamping (240mA), and thermal shutdown at +145°C with +15°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±2% over -40°C to +85°C ambient; ensures stable core/I/O rail for FPGA/DSP without external feedback resistors. |
| Max Output Current | 600mA continuous; supports mid-power digital loads such as ARM Cortex-A series I/O domains or sensor interface ASICs. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥2.5V); enables operation from single-cell Li-ion (3.0V min) or two-cell alkaline (3.0V nominal) sources. |
| Quiescent Current | 35μA typical at zero load; extends battery life in always-on monitoring circuits and low-duty-cycle IoT endpoints. |
| PSRR | 65dB at 1kHz; suppresses switching noise from adjacent DC-DC converters feeding mixed-signal SoCs. |
| Start-Up Time | 200μs typical; allows rapid wake-up from deep sleep in portable devices without brownout risk. |
| Thermal Resistance θJA | 142°C/W (SOT223-E package); requires minimal copper area for thermal management in space-constrained PCBs. |
Pinout & Package
SOT223-E package with exposed thermal pad (pin 3 = IN, pin 2 = GND, pin 1 = OUT); optimized for thermal performance in high-current LDO applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Regulated output voltage terminal | Delivers stable 3.0V to load; requires 1μF ceramic capacitor placed adjacent to pin for transient stability. |
| GND (Pin 2) | Power ground reference | Common return path for input/output currents; must connect directly to thermal pad and system ground plane. |
| IN (Pin 3) | Input voltage supply terminal | Accepts 2V–6V input; bypassed with ≥1μF MLCC close to pin to suppress supply ripple and EMI. |
| EN (Not present) | Enable control input | Not implemented in SOT223-E fixed-output variant; device operates continuously when powered. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout voltage | 300mV at 600mA enables regulation from 3.3V input down to 3.0V output - critical for battery voltage sag compensation. |
| Fast transient response | Stable under 10mA ↔ 600mA load steps with <20mV overshoot/undershoot - sustains clean power during burst-mode DSP execution. |
| High PSRR | 65dB at 1kHz rejects noise from shared PMIC switchers, preventing jitter in ADC clock domains or RF synthesizers. |
| Thermal shutdown with hysteresis | +145°C trip / +130°C recovery prevents latch-up during overload while allowing safe self-recovery without system reset. |
| Stability with low-ESR capacitors | Guaranteed stable with 1μF ceramic output capacitor (ESR >15mΩ) - eliminates need for bulky tantalum or aluminum electrolytics. |
Applications
| Portable Medical Sensors | FPGA I/O Power |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3002E/TT | 300mA max output, 2μA IQ, 6V max input, SOT23-3 package | Limited to low-power MCU peripherals; insufficient for FPGA I/O or audio DSP loads | Select only for ultra-low-power sensor nodes where 300mA peak current suffices. |
| TPS7A2030PDBVR | 300mA max output, 25μA IQ, 6.5V max input, 1.1mm × 1.3mm X2SON package | Lower current rating and smaller thermal mass; unsuitable for sustained 600mA operation | Prefer for space-constrained wearables with sub-300mA loads; avoid for FPGA or motor driver bias rails. |
Compared with MCP1700T-3002E/TT and TPS7A2030PDBVR, AP7365-30EG-13 delivers double the output current (600mA vs. 300mA) in a thermally robust SOT223 package, making it uniquely suitable for mid-power digital loads requiring both low IQ and high current capability without derating.

FAQ
What is the maximum input voltage for AP7365-30EG-13?
The absolute maximum input voltage is 6.5V, but the recommended operating range is 2V to 6V. Exceeding 6V risks permanent damage per Absolute Maximum Ratings. At VIN = 6V, power dissipation reaches (6V − 3V) × 600mA = 1.8W - requiring adequate PCB copper area to maintain junction temperature below +150°C.
Does AP7365-30EG-13 require an external enable signal?
No. The SOT223-E package variant (suffix -EG-13) is a fixed-output version without EN pin functionality. It operates continuously when input voltage is applied. Enable control is only available in SOT25 and U-DFN2020-6 packages with ADJ or fixed outputs.
Can AP7365-30EG-13 be used with a 1μF output capacitor?
Yes. The datasheet explicitly guarantees stability with a 1μF ceramic capacitor having ESR >15mΩ. Larger capacitance improves load transient response, but 1μF is the minimum required for guaranteed stability across temperature and process variation.
What thermal considerations apply to the SOT223-E package?
The SOT223-E package has θJA = 142°C/W on standard FR-4 with 1oz copper. To avoid thermal shutdown at 600mA, ambient temperature must remain ≤+75°C when VIN = 5V (PD = 1.2W). Use of thermal vias under the exposed pad reduces θJA by ~20–30°C in production layouts.
