Product details
Overview
AP7365-15YRG-13 from Diodes Incorporated is a 600mA fixed-output low-dropout linear regulator with 1.5V output, 35μA quiescent current, 300mV dropout at full load, and SOT89-3 package. It integrates enable control, thermal shutdown, and current limiting for battery-powered FPGA I/O rails and portable consumer electronics requiring stable low-noise voltage regulation.
For engineers reviewing the AP7365-15YRG-13 datasheet, AP7365-15YRG-13 pinout, AP7365-15YRG-13 application, or AP7365-15YRG-13 equivalent, this page delivers verified electrical parameters, validated SOT89-3 terminal mapping, real-world transient response behavior, and confirmed drop-in alternatives for industrial and embedded power design.
Technical Context
The AP7365-15YRG-13 implements a PMOS pass transistor architecture enabling 300mV dropout at 600mA and 1.5V output, with internal 0.8V bandgap reference and error amplifier driving gate control. Its EN pin accepts 1.4V logic-high threshold to activate regulation, while shutdown draws only 0.1μA.
Stability is achieved with ≥1μF ceramic output capacitance (ESR >15mΩ), and PSRR reaches 65dB at 1kHz due to high-loop-gain error amplifier design. Fast 200μs startup and excellent load transient response (≤200mV deviation at 600mA step) support dynamic DSP core power sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5V ±2% over -40°C to +85°C - ensures precise core voltage for 1.5V FPGA I/O banks. |
| Max Output Current | 600mA continuous - supports moderate-power digital loads without external heat sinking in SOT89. |
| Quiescent Current | 35μA typical - extends battery runtime in always-on sensor nodes and standby subsystems. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥2.5V), 370mV at 600mA (VOUT <2.5V) - enables operation down to 1.8V input for single-cell Li-ion systems. |
| PSRR | 65dB at 1kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Start-Up Time | 200μs - meets fast wake-up timing for low-power microcontrollers exiting deep sleep. |
| Thermal Shutdown | Triggers at +145°C with +15°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal layout. |
Pinout & Package
SOT89-3 (YR package) with exposed thermal pad on pin 3 (GND). Compact 4.5mm × 2.5mm footprint optimized for space-constrained portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 3) | Voltage Input | Accepts 2V–6V supply; requires ≥1μF MLCC decoupling to GND for stability and noise rejection. |
| GND (Pin 1) | Ground Reference | Primary return path and thermal conduction node; must connect to large copper pour for thermal management. |
| OUT (Pin 2) | Voltage Output | Delivers regulated 1.5V; bypassed with ≥1μF ceramic capacitor to minimize load transient undershoot. |
Key Features
| Feature | Design Value |
|---|---|
| Low IQ Operation | 35μA quiescent current enables >1-year battery life in 10μA average-load IoT sensors. |
| Fast Transient Response | ≤200mV output deviation during 10mA→600mA load steps - sustains logic integrity for burst-mode processors. |
| Integrated Protection | Current limit (~1.4A), short-circuit clamp (~240mA), and thermal shutdown prevent field failures under fault conditions. |
| Small-Capacitor Stability | Stable with 1μF ceramic output capacitor (ESR >15mΩ) - eliminates need for bulky tantalum or electrolytic caps. |
| Enable Control | Logic-compatible EN pin (VIH = 1.4V) allows microcontroller-driven power gating of peripheral rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1502E/TT | 300mA max output, 2.5μA IQ, SOT23-3 package - lower current, far lower quiescent current. | Best for sub-100mA always-on sensors where IQ dominates lifetime; insufficient for 600mA FPGA I/O. | Select when battery life > performance; avoid if peak load exceeds 300mA. |
| Torex XC6210B152MR-G | 1A max output, 8μA IQ, 250mV dropout at 1A, SOT23-5 with CE pin - higher current, lower dropout, smaller package. | Supports higher-current peripherals; CE pin logic differs (active-low vs. AP7365's active-high EN). | Choose for space-constrained 1A designs; verify EN/CE logic compatibility in system-level control firmware. |
Compared with MCP1700T-1502E/TT, AP7365-15YRG-13 delivers 2× output current and faster transient response but trades 10× higher IQ; versus XC6210B152MR-G, it offers simpler enable logic and proven thermal robustness in SOT89, at the cost of larger footprint and slightly higher dropout.

FAQ
What is the minimum input voltage required for AP7365-15YRG-13 to maintain regulation?
The device operates with input voltages from 2.0V to 6.0V. To sustain 1.5V output at 600mA, VIN must be ≥1.8V (1.5V + 300mV dropout). Below 1.8V, output voltage collapses linearly per the dropout curve - no regulation is maintained below VIN = VOUT + VDROPOUT.
Can AP7365-15YRG-13 be used without an output capacitor?
No. A minimum 1μF ceramic capacitor with ESR >15mΩ is mandatory on the OUT pin for stability. Omitting it causes oscillation and unregulated output. The datasheet explicitly states "output capacitor is required to stabilize and improve transient response" and defines the stable COUT–ESR region across load current.
Is the EN pin internally pulled up or down?
The EN pin has no internal pull-up or pull-down. It is a high-impedance CMOS input requiring external biasing. If unused, it must be tied directly to IN (not VOUT or GND) to ensure reliable turn-on; floating EN may cause erratic enable/disable behavior due to noise coupling.
Does AP7365-15YRG-13 support reverse polarity protection?
No. The device lacks integrated reverse-voltage protection. Applying negative voltage to IN or OUT relative to GND violates absolute maximum ratings and may cause latch-up or permanent damage. External protection diodes or MOSFET-based circuits are required for reverse-polarity resilience.
