Product details
Overview
AP7365-25YRG-13 from Diodes Incorporated is a fixed-output 2.5V, 600mA low-dropout linear regulator in SOT89-3 package with enable control, 35μA quiescent current, 300mV dropout at full load, and ±2% output voltage accuracy over –40°C to +85°C. It delivers stable power to FPGA I/O rails and battery-powered portable electronics requiring fast transient response and ultra-low standby consumption.
For engineers reviewing the AP7365-25YRG-13 datasheet, AP7365-25YRG-13 pinout, AP7365-25YRG-13 application, or AP7365-25YRG-13 equivalent, key selection criteria include dropout voltage at 600mA, EN logic thresholds (VIH = 1.4V, VIL = 0.4V), thermal shutdown threshold (+145°C), PSRR (65dB @ 1kHz), and compatibility with 1μF ceramic output capacitors.
Technical Context
The AP7365-25YRG-13 integrates a PMOS pass element, precision 0.8V bandgap reference, error amplifier, current-limit circuitry, and thermal shutdown protection. Its fixed 2.5V output eliminates external feedback resistors, simplifying layout while maintaining regulation under dynamic loads up to 600mA.
It operates across 2V–6V input range with fast 200μs startup time and excellent line/load transient response-critical for powering DSP cores and GSM baseband circuits where load steps from 10mA to 600mA occur in microseconds without overshoot or droop exceeding ±20mV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5V ±2% over –40°C to +85°C; enables direct replacement of legacy 2.5V LDOs without resistor recalibration. |
| Max Output Current | 600mA continuous; supports FPGA I/O banks and microcontroller peripherals without external current boosting. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥ 2.5V); allows operation from 2.8V input while sustaining full load-ideal for single-cell Li-ion or dual-cell NiMH systems. |
| Quiescent Current | 35μA typical at zero load; extends battery runtime in always-on sensor nodes and IoT edge devices. |
| PSRR | 65dB at 1kHz; suppresses switching noise from upstream DC/DC converters feeding sensitive analog or RF circuitry. |
| Enable Threshold | VIH = 1.4V min, VIL = 0.4V max; compatible with 1.8V/3.3V GPIOs for precise system-level power sequencing. |
| Thermal Shutdown | Triggers at +145°C junction temperature with +15°C hysteresis; prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
SOT89-3 (YR package) with exposed thermal pad on pin 3 (GND). Compact 4.5mm × 2.5mm footprint optimized for high thermal conductivity on 1oz copper PCBs (θJA = 133°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: IN | Input voltage supply | Accepts 2V–6V; requires ≥1μF ceramic bypass capacitor placed adjacent to pin to suppress input ripple and ensure stability. |
| 2: GND | Ground reference and thermal path | Internal connection to exposed thermal tab; must be soldered to ≥25mm² copper pour for reliable 600mA operation. |
| 3: OUT | Regulated 2.5V output | Delivers up to 600mA; stable with ≥1μF ceramic capacitor (ESR >15mΩ); output voltage tolerance remains ±2% across full load and temperature range. |
| EN (pin not present) | Enable control | Not implemented in YR-package fixed-output variant; device is permanently enabled-no external pull-up required. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout architecture | 300mV dropout at 600mA enables use with input as low as 2.8V-critical for brownout resilience in portable systems. |
| Fast transient response | Stabilizes within <50μs after 10mA→600mA load step; maintains <±20mV output deviation-meets GSM/TDMA baseband timing requirements. |
| Ultra-low IQ | 35μA quiescent current reduces no-load power loss to <88μW at 2.5V-extends shelf life of coin-cell–powered devices. |
| Integrated protection | Current limit (~1.4A), short-circuit clamp (240mA), and thermal shutdown prevent field failures under fault conditions without external components. |
| Capacitor flexibility | Stable with 1μF ceramic output capacitor (ESR >15mΩ); eliminates need for costly tantalum or large electrolytics in space-constrained designs. |

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 |
|---|---|---|---|
| MCP1700-2502E/TO | 300mA max output, 2μA IQ, TO-92 package; lacks EN pin and thermal shutdown. | Suitable only for ultra-low-power, non-automotive, sub-300mA loads; cannot replace AP7365-25YRG-13 in FPGA or DSP applications. | Select only when load current ≤300mA and thermal protection is unnecessary-requires external thermal monitoring. |
| Torex XC6206P252MR-G | 250mA max output, SOT-23-3, 1μA IQ; no current limit or thermal shutdown. | Limited to micropower sensor biasing; incompatible with 600mA FPGA I/O or DSP core loads. | Use exclusively for <100μA standby-sensitive applications where cost and size outweigh performance and protection needs. |
Compared with MCP1700-2502E/TO and XC6206P252MR-G, the AP7365-25YRG-13 uniquely combines 600mA drive capability, integrated thermal/current protection, and 35μA IQ in a thermally robust SOT89 package-making it the only viable choice for industrial FPGA and automotive body control applications requiring both high current and fault resilience.

FAQ
Is AP7365-25YRG-13 pin-compatible with other SOT89-3 LDOs?
No-AP7365-25YRG-13 uses IN/GND/OUT pinout (YR package), whereas most legacy SOT89-3 regulators (e.g., MIC5205) use IN/OUT/GND. Swapping requires PCB layout revision due to reversed GND/OUT placement and absence of EN pin in this fixed-output variant.
What is the minimum input voltage required to maintain 2.5V output at 600mA?
The minimum input is 2.8V: dropout voltage is 300mV at 600mA (VOUT ≥ 2.5V), so VIN(min) = VOUT + VDROPOUT = 2.5V + 0.3V = 2.8V. Below 2.8V, output regulation fails and voltage drops linearly with input.
Can AP7365-25YRG-13 operate without an output capacitor?
No-it requires ≥1μF ceramic output capacitor (ESR >15mΩ) for stability. Omitting it causes oscillation and output voltage collapse under load, as confirmed by stability analysis in DS32260 Rev. 11 Section 8.2 and Figure 12's COUT-ESR vs. load current plot.
Does AP7365-25YRG-13 meet AEC-Q100 automotive qualification?
No-the datasheet states AEC-Q100 qualification requires explicit contact with Diodes sales for PPAP-capable, IATF 16949-manufactured variants. AP7365-25YRG-13 is standard commercial-grade; its -40°C to +85°C rating supports industrial but not automotive-grade reliability requirements.
