Product details
Overview
AP7365-25YG-13 from Diodes Incorporated is a fixed-output 2.5V, 600mA low-dropout linear regulator in SOT89 package with 35μA quiescent current, 300mV dropout at full load, and integrated enable control, thermal shutdown, and current limiting-designed for FPGA I/O power and battery-powered portable electronics.
For engineers reviewing the AP7365-25YG-13 datasheet, AP7365-25YG-13 pinout, AP7365-25YG-13 application, or AP7365-25YG-13 equivalent, key selection criteria include dropout voltage at 600mA, PSRR at 1kHz, start-up time, thermal resistance (θJA = 133°C/W), and compatibility with 1μF ceramic output capacitors.
Technical Context
The AP7365-25YG-13 implements a PMOS pass transistor architecture enabling low dropout (300mV @ 600mA, VOUT ≥ 2.5V) and high PSRR (65dB @ 1kHz). Its internal 0.8V bandgap reference and error amplifier regulate output precisely across –40°C to +85°C ambient.
Enable logic operates with VIH ≥ 1.4V and VIL ≤ 0.4V, supporting direct microcontroller GPIO control. Protection circuitry includes foldback current limiting (1.4A typical), 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 and full load range |
| Max Output Current | 600mA continuous; internal current limit prevents damage above 1.4A |
| Dropout Voltage | 300mV at 600mA (VOUT ≥ 2.5V); enables operation with VIN as low as 2.8V |
| Quiescent Current | 35μA typical at zero load; critical for battery runtime in always-on systems |
| PSRR | 65dB at 1kHz; suppresses switching noise from upstream DC/DC converters |
| Start-Up Time | 200μs from EN high to regulated VOUT; supports fast wake-up in low-power modes |
| Thermal Resistance θJA | 133°C/W (SOT89-Y package); requires minimal PCB copper area for thermal management |
Pinout & Package
SOT89-Y package (3-pin, tab-connected to GND), thermally enhanced for power dissipation up to 0.8W at +85°C ambient with standard layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output voltage node | Must be bypassed with ≥1μF ceramic capacitor placed adjacent to pin; connects to load and feedback path |
| 2 (GND) | Power ground reference | Low-impedance return path; electrically tied to exposed thermal tab for heat conduction |
| 3 (IN) | Input voltage supply node | Requires ≥1μF ceramic decoupling capacitor; accepts 2V–6V input range |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 35μA quiescent current enables >1-year battery life in 10μA standby IoT sensors |
| Fast transient response | Stable under 10mA ↔ 600mA load steps without external compensation; supports GSM/DSP burst loads |
| Single-capacitor stability | Guaranteed stable with 1μF ceramic output capacitor (ESR > 15mΩ); reduces BOM count and board space |
| Integrated protection | Current limit, thermal shutdown, and short-circuit clamp eliminate need for external fault management circuitry |
| Enable control | Active-high EN pin allows precise sequencing and system-level power gating with <1μA shutdown current |
Applications
| Portable Medical Sensors | FPGA I/O Power Rails |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-2502E/TO | 300mA max output, 2.5V fixed, 1.6μA IQ, TO-92 package | Limited to ultra-low-current applications; lacks enable pin and thermal shutdown | Select only for sub-100mA, cost-sensitive designs where enable and protection are not required |
| TPS7A0525PDBVR | 200mA max output, 2.5V fixed, 25μA IQ, SOT-23-5 with enable | Lower current capability and higher dropout (450mV @ 200mA); superior IQ but insufficient for 600mA FPGA rails | Prefer for space-constrained, low-IQ sensor nodes-not for high-current digital loads |
Compared with MCP1700-2502E/TO and TPS7A0525PDBVR, the AP7365-25YG-13 uniquely delivers 600mA output, 300mV dropout, and full protection set in SOT89-making it the only viable choice for FPGA I/O and portable medical devices needing both high current and ultra-low IQ.

FAQ
What is the minimum input voltage required for AP7365-25YG-13 to maintain 2.5V output at 600mA?
The AP7365-25YG-13 requires a minimum input voltage of 2.8V to sustain 2.5V output at 600mA load, based on its 300mV dropout specification (VIN(min) = VOUT + VDROPOUT). Operation below 2.8V results in unregulated output and potential dropout failure.
Can AP7365-25YG-13 operate without an output capacitor?
No. The AP7365-25YG-13 requires a minimum 1μF ceramic output capacitor with ESR > 15mΩ for stability, as confirmed in the datasheet's Application Information section. Omitting this capacitor causes oscillation and loss of regulation under load transients.
Is the thermal pad on the SOT89-Y package electrically connected, and how should it be handled on the PCB?
Yes-the thermal tab on the SOT89-Y package is internally connected to GND. It must be soldered to a dedicated GND copper pour using multiple thermal vias to achieve the specified θJA = 133°C/W; floating or isolated connection degrades thermal performance and risks thermal shutdown.
Does AP7365-25YG-13 support reverse polarity protection or input overvoltage tolerance?
No. The AP7365-25YG-13 has no built-in reverse-polarity or overvoltage protection. Absolute maximum input voltage is 6.5V; exceeding this risks permanent damage. External TVS diodes or series MOSFETs are required for systems exposed to voltage surges or incorrect battery insertion.
