Product details
Overview
AP7365-15EG-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 integrated enable control. It operates from 2V to 6V input, delivers ±2% output accuracy across –40°C to +85°C, and stabilizes with only 1μF ceramic output capacitance - ideal for FPGA I/O rail and battery-powered portable electronics.
For engineers reviewing the AP7365-15EG-13 datasheet, AP7365-15EG-13 pinout, AP7365-15EG-13 application, or AP7365-15EG-13 equivalent, key selection criteria include dropout voltage under 600mA load, thermal shutdown threshold at +145°C, PSRR of 65dB at 1kHz, and compatibility with SOT223-E package layout and thermal pad grounding.
Technical Context
The AP7365-15EG-13 implements a PMOS pass transistor architecture enabling low dropout (300mV @ 600mA) and fast transient response without requiring external compensation. Its bandgap reference (0.8V) and error amplifier regulate output precisely despite line/load variations.
Enable logic operates with VIH ≥1.4V and VIL ≤0.4V, supporting direct microcontroller GPIO control. Built-in current limit (~1.4A), short-circuit protection (~240mA), and thermal shutdown (+145°C trip, +130°C hysteresis) provide fault resilience in compact power domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5V ±2% over –40°C to +85°C - ensures stable core/I/O supply for low-voltage logic. |
| Max Output Current | 600mA continuous - supports mid-power FPGA I/O banks and DSP peripherals. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥2.5V); 370mV max at 600mA (VOUT <2.5V) - enables operation down to 1.8V input for 1.5V rail. |
| Quiescent Current | 35μA typical (0–6V input range) - extends battery life in always-on sensor nodes and wearables. |
| PSRR | 65dB at 1kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Start-Up Time | 200μs - allows rapid power sequencing in multi-rail systems with tight timing budgets. |
| Thermal Shutdown | +145°C trip with +15°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
AP7365-15EG-13 uses the SOT223-E package: 3-pin outline with exposed thermal pad (pin 3 = IN, pin 1 = GND, pin 2 = OUT). The thermal pad must be soldered to a dedicated copper pour for effective heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 3) | Input voltage supply | Accepts 2V–6V; requires ≥1μF MLCC bypass to GND near pin for stability and noise rejection. |
| GND (Pin 1) | Power ground reference | Low-impedance return path; connects to thermal pad for junction-to-board heat transfer. |
| OUT (Pin 2) | Regulated output | Delivers fixed 1.5V; requires ≥1μF ceramic capacitor to GND for transient response and phase margin. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 35μA enables >1-year battery life in coin-cell–powered IoT endpoints with 10μA average system current. |
| Fast transient response | Stabilizes within 100μs during 10mA→600mA load steps - maintains <±20mV droop for GSM/DSP burst-mode loads. |
| Single-capacitor stability | Works with 1μF ceramic output cap (ESR >15mΩ) - eliminates need for bulky tantalum or electrolytic capacitors. |
| Integrated protection | Current limit (1.4A), short-circuit clamp (240mA), and thermal shutdown prevent field failures in unattended deployments. |
| Wide input range | 2V–6V operation supports single-cell Li-ion (3.0–4.2V), dual-cell alkaline (2.4–3.2V), and USB-powered systems. |
Applications
| FPGA I/O Power | DSP Core Supply |

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 |
|---|---|---|---|
| MCP1700T-1502E/MB | 300mA max output, 2.0μA IQ, SOT23-3 package - lower current, far lower IQ, no enable pin. | Suitable only for sub-300mA sensor bias rails; lacks EN control for power sequencing. | Select when ultra-low IQ dominates over current capability and enable functionality is unnecessary. |
| Torex XC6206P152MR-G | 500mA max output, 1.0μA IQ, no thermal shutdown, SOT23-3 - smaller package, no fault protection. | Applicable in cost-sensitive consumer devices where thermal derating is managed externally. | Choose for minimal footprint and lowest possible IQ where board-level thermal design mitigates risk. |
Compared with MCP1700T-1502E/MB and XC6206P152MR-G, the AP7365-15EG-13 uniquely combines 600mA drive, 35μA IQ, integrated EN, and full fault protection in a thermally enhanced SOT223 package - making it optimal for industrial and portable designs demanding robustness and scalability.

FAQ
What is the minimum input voltage required for AP7365-15EG-13 to maintain regulation at 600mA?
The device requires VIN ≥ VOUT + VDROPOUT. With VOUT = 1.5V and max dropout of 370mV (per datasheet Table 1, VOUT <2.5V condition), minimum VIN is 1.87V. However, the recommended operating minimum is 2.0V to ensure margin across temperature and process variation.
Can AP7365-15EG-13 operate without an output capacitor?
No. The datasheet mandates a minimum 1μF ceramic output capacitor with ESR >15mΩ for stability. Omitting it causes oscillation and output voltage collapse under load, as confirmed by stability testing in Figure 12 and Application Information section.
Is the thermal pad on the SOT223-E package electrically connected?
Yes - the exposed thermal pad (tab) is internally connected to GND. It must be soldered to a PCB copper pour tied to the system ground plane to achieve specified θJA = 142°C/W and prevent thermal shutdown during sustained 600mA operation.
Does AP7365-15EG-13 support reverse polarity protection?
No. The device lacks internal reverse-voltage blocking. Applying reversed input voltage may damage the pass transistor. External protection - such as a series Schottky diode or MOSFET-based ideal diode - is required if reverse polarity exposure is possible in the application.
