Product details
Overview
AP7365-25EG-13 from Diodes Incorporated is a fixed-output 2.5V, 600mA low-dropout linear regulator with enable control, 35μA quiescent current, 300mV dropout at full load, and stable operation with 1μF ceramic output capacitor. It delivers precision voltage regulation for FPGA I/O rails and battery-powered portable electronics requiring fast transient response and thermal protection.
For engineers reviewing the AP7365-25EG-13 datasheet, AP7365-25EG-13 pinout, AP7365-25EG-13 application, or AP7365-25EG-13 equivalent, key selection criteria include dropout voltage at 600mA, EN logic thresholds (VIH = 1.4V, VIL = 0.4V), ±2% output accuracy over –40°C to +85°C, PSRR of 65dB at 1kHz, and compatibility with SOT223-E package thermal performance (θJA = 142°C/W).
Technical Context
The AP7365-25EG-13 integrates a PMOS pass element, bandgap reference, error amplifier, and thermal shutdown circuitry in a fixed 2.5V configuration. Its architecture enables ultra-low quiescent current (35μA typ.) without sacrificing transient response-achieving 200μs startup and robust load/line regulation (±1.0% max) across 0–600mA.
It operates across 2V–6V input range and maintains stability with 1μF ceramic output capacitors (ESR ≥15mΩ). Built-in protections include current limiting (1.4A typ.), short-circuit clamping (240mA), and thermal shutdown activation at +145°C with +15°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5V ±2% over –40°C to +85°C - ensures reliable core/I/O rail compliance for FPGA and DSP interfaces. |
| Max Output Current | 600mA continuous - supports moderate-power digital loads without external current boosting. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥2.5V) - enables operation down to VIN = 2.8V, critical for single-cell Li-ion or 3.3V system bus margin. |
| Quiescent Current | 35μA typical - extends battery life in always-on or low-duty-cycle portable devices (e.g., IoT sensors, wearables). |
| PSRR | 65dB at 1kHz - suppresses switching noise from adjacent DC-DC converters feeding mixed-signal circuits. |
| Start-Up Time | 200μs - allows rapid power sequencing in multi-rail systems and dynamic power-state transitions. |
| Thermal Shutdown | Activates at +145°C with +15°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
SOT223-E package (3-pin, exposed thermal pad on tab) with standard pin assignment: Pin 1 = OUT, Pin 2 = GND, Pin 3 = IN. The thermal pad (TAB) must be soldered to a minimum 100mm² copper pour for θJA = 142°C/W performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Regulated output voltage node | Delivers stable 2.5V; requires 1μF ceramic capacitor placed within 2mm of pin for transient stability. |
| GND (Pin 2) | Reference and return path | Low-impedance ground connection essential for PSRR and thermal pad conduction; must tie directly to thermal pad. |
| IN (Pin 3) | Unregulated input supply | Accepts 2V–6V; bypassed with ≥1μF MLCC close to pin to suppress high-frequency ripple and EMI. |
Key Features
| Feature | Design Value |
|---|---|
| Enable control with logic-level thresholds | VIH = 1.4V min, VIL = 0.4V max - compatible with 1.8V/3.3V GPIO without level-shifting. |
| Stability with minimal capacitance | Guaranteed stable with 1μF ceramic output capacitor (ESR ≥15mΩ) - reduces BOM cost and board space vs. larger electrolytics. |
| Fast load transient recovery | ≤20mV undershoot/overshoot for 10mA ↔ 600mA step at 3.3V input - maintains clean supply for high-speed digital logic. |
| Integrated fault protection | Current limit (1.4A), short-circuit clamp (240mA), and thermal shutdown - eliminates need for external protection circuitry. |
| Green, RoHS-compliant construction | Totally lead-free, halogen- and antimony-free - meets IPC-1752A material declaration and automotive change-control requirements. |

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 |
|---|---|---|---|
| AP7361-25WG-7 | Same 2.5V fixed output but rated for 300mA max; SOT25 package (θJA = 169°C/W); higher dropout (450mV @ 300mA) | Lower power I/O rails where thermal budget permits smaller package; not suitable for 600mA loads | Select when board space is constrained and load current ≤300mA; verify thermal rise with 169°C/W junction-to-ambient. |
| MCP1700T-2502E/TT | 2.5V fixed, 250mA max, 1.6μA IQ, SOT23-3; no enable pin; 600mV dropout @ 250mA | Ultra-low-power always-on bias rails (e.g., RTC, sensor wake-up circuitry); lacks EN control and current capability | Choose only for sub-250mA, ultra-low-IQ applications where enable functionality is unnecessary and dropout margin is acceptable. |
Compared with AP7365-25EG-13, AP7361-25WG-7 trades 300mA current capacity and higher thermal resistance for smaller SOT25 footprint, while MCP1700T-2502E/TT sacrifices 600mA delivery and EN control to achieve nanoscale quiescent current-making AP7365-25EG-13 the sole fit for thermally demanding, enable-controlled 2.5V/600mA applications in SOT223.

FAQ
Is AP7365-25EG-13 compatible with ceramic output capacitors smaller than 1μF?
No. The datasheet specifies stability with ≥1μF ceramic output capacitors having ESR ≥15mΩ. Using smaller values risks oscillation or excessive transient overshoot/undershoot, particularly under 600mA load steps. Minimum 1μF is required for guaranteed stability across –40°C to +85°C.
What is the maximum allowable input voltage for AP7365-25EG-13?
The absolute maximum input voltage is 6.5V, but recommended operating range is 2V to 6V. Exceeding 6V risks permanent damage. At VIN = 6V and IOUT = 600mA, power dissipation reaches 2.1W-requiring careful thermal design with the SOT223-E package's 142°C/W θJA to avoid thermal shutdown.
Can the EN pin be left floating?
No. The EN pin must be actively driven: tied to IN for always-on operation or controlled by a logic signal. Floating EN may cause erratic turn-on/turn-off due to noise susceptibility, leading to unstable output or repeated thermal cycling. A pull-up resistor to IN is acceptable if GPIO control is unavailable.
Does AP7365-25EG-13 require a minimum load current for regulation stability?
No. The device remains stable and fully regulated with zero load current. This is confirmed in the datasheet's "No Load Stability" section and enables use in standby modes where downstream circuitry draws negligible current-critical for battery longevity in intermittent-sensing applications.
