Product details
Overview
AP7365-15YG-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 enable control. It operates from 2V to 6V input, delivers ±2% output accuracy across –40°C to +85°C, and stabilizes with a single 1μF ceramic output capacitor. It is used in FPGA I/O power rails where fast transient response and ultra-low IQ are critical.
For engineers reviewing the AP7365-15YG-13 datasheet, AP7365-15YG-13 pinout, AP7365-15YG-13 application, or AP7365-15YG-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 SOT89-Y package thermal resistance (θJA = 133°C/W).
Technical Context
The AP7365-15YG-13 implements a PMOS pass transistor architecture enabling low dropout and high PSRR. Its internal 0.8V bandgap reference feeds an error amplifier that regulates output by modulating gate drive to the pass element.
Enable functionality uses TTL-compatible input logic with hysteresis-free thresholds; thermal shutdown engages at +145°C junction temperature and recovers at +130°C. Current limit is set to 1.4A for overload protection and 240mA for short-circuit clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5V ±2% over –40°C to +85°C; enables direct powering of 1.5V I/O domains without external resistors. |
| Max Output Current | 600mA continuous; supports mid-power digital loads like FPGA banks or microcontroller peripherals. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥ 2.5V); for 1.5V output, typical dropout is 370mV - ensures regulation down to VIN = 1.87V. |
| Quiescent Current | 35μA typical at zero load; minimizes standby power loss in battery-backed systems. |
| PSRR | 65dB at 1kHz; suppresses ripple from noisy DC/DC converters feeding the LDO input. |
| Start-Up Time | 200μs from EN assertion to regulated output; supports rapid wake-up in duty-cycled applications. |
| Thermal Shutdown | Triggers at +145°C junction temperature with +15°C hysteresis; prevents permanent damage during sustained overload. |
Pinout & Package
AP7365-15YG-13 is packaged in SOT89-Y (Y Package), featuring a thermally enhanced 3-pin outline with exposed tab connected to GND. The tab must be soldered to a minimum 25 mm² copper pour for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated Output | Delivers stable 1.5V; requires 1μF ceramic capacitor placed adjacent to pin and GND. |
| 2 (GND) | Ground Reference | Common return path for input, output, and EN; connects to exposed thermal tab. |
| 3 (IN) | Input Supply | Accepts 2V–6V; bypassed with ≥1μF MLCC close to pin to suppress supply noise. |
Key Features
| Feature | Design Value |
|---|---|
| Low Dropout Architecture | PMOS pass device enables 300mV dropout at 600mA, allowing operation with minimal VIN–VOUT margin. |
| Fast Transient Response | Stabilizes within <50μs under 10mA→600mA load steps - maintains voltage integrity for burst-mode DSP cores. |
| Ultra-Low IQ | 35μA quiescent current reduces no-load power dissipation to <52.5nW per volt of VIN - critical for multi-week battery life. |
| EN-Controlled Operation | Active-high enable with VIH = 1.4V allows direct interfacing with 1.8V/3.3V GPIO without level-shifting. |
| Robust Protection Suite | Integrated current limit (1.4A), short-circuit clamp (240mA), and thermal shutdown (+145°C) eliminate need for external fault management. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-1502E/TO | 300mA max output, 2μA IQ, SOT23-3 package, no EN pin | Limited to lower-current sensor interfaces; lacks enable control for power sequencing | Select when ultra-low IQ dominates over current capability and EN is unnecessary |
| Torex XC6210B152MR-G | 400mA max output, 1.0μA IQ, 150mV dropout at 100mA, SOT25 package | Insufficient current headroom for 600mA FPGA I/O; lower thermal mass in SOT25 limits sustained power | Prefer only for space-constrained, low-duty-cycle 1.5V loads where <1μA IQ is mandatory |
Compared with MCP1700-1502E/TO and XC6210B152MR-G, AP7365-15YG-13 uniquely balances 600mA delivery, 35μA IQ, EN control, and SOT89 thermal performance - making it the only viable choice for thermally demanding, medium-power 1.5V applications requiring fast transient immunity.

FAQ
What is the minimum input voltage required for AP7365-15YG-13 to maintain regulation at 600mA?
The AP7365-15YG-13 requires VIN ≥ VOUT + VDROPOUT. With VOUT = 1.5V and typical dropout = 370mV (per datasheet Table 1, "VDROPOUT" for VOUT < 2.5V), minimum VIN is 1.87V. Absolute minimum per Absolute Maximum Ratings is 2.0V - thus 2.0V is the practical lower bound for reliable 600mA operation.
Can AP7365-15YG-13 be used without an input capacitor?
No. The datasheet mandates a minimum 1μF ceramic capacitor between IN and GND to ensure stability and suppress input transients. Omitting it risks oscillation, poor PSRR, and potential EN false triggering due to supply bounce. Layout best practice requires placing this capacitor within 2mm of the IN and GND pins.
Is the SOT89-Y package lead-free and RoHS-compliant?
Yes. AP7365-15YG-13 is fully RoHS 3 compliant (2015/863/EU), lead-free, halogen-free, and antimony-free per Diodes' "Green" definition (<900ppm Br, <900ppm Cl, <1000ppm Sb). The "G" suffix in the part number explicitly denotes green packaging.
Does AP7365-15YG-13 require a minimum load current to remain stable?
No. The device remains stable and regulated at zero load, as confirmed in the Application Information section: "No minimum load is required to keep the device stable." This eliminates the need for dummy loads in low-power standby modes, preserving system efficiency.
