Product details
Overview
AP7365-28YG-13 from Diodes Incorporated is a fixed-output 2.8V, 600mA low-dropout linear regulator in SOT89 package with enable control, 35μA quiescent current, 300mV dropout at full load, and integrated thermal shutdown and current-limit protection. It powers FPGA I/O rails and battery-powered consumer electronics requiring stable low-noise voltage under fast load transients.
For engineers reviewing the AP7365-28YG-13 datasheet, AP7365-28YG-13 pinout, AP7365-28YG-13 application, or AP7365-28YG-13 equivalent, this page delivers verified electrical parameters, SOT89 terminal mapping, thermal performance data, and real-world use cases for portable and embedded power design.
Technical Context
The AP7365-28YG-13 implements a PMOS pass transistor architecture enabling low dropout (300mV @ 600mA) and high PSRR (65dB @ 1kHz). Its internal 0.8V bandgap reference and error amplifier regulate output with ±2% accuracy across –40°C to +85°C ambient.
Enable logic operates with VIH ≥ 1.4V and VIL ≤ 0.4V, supporting direct microcontroller GPIO control. Built-in 145°C thermal shutdown with 15°C hysteresis and 240mA short-circuit current limit ensure robust fault handling without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8V ±2% - ensures precise biasing for 2.8V I/O standards (e.g., SDIO, USB PHY) |
| Max Output Current | 600mA - supports mid-power digital loads like FPGA I/O banks or MCU peripherals |
| Quiescent Current | 35μA typical - extends battery life in always-on sensor nodes and standby modes |
| Dropout Voltage | 300mV @ 600mA - enables operation down to VIN = 3.1V, critical for single-cell Li-ion systems |
| PSRR | 65dB @ 1kHz - suppresses switching noise from adjacent DC/DC converters feeding mixed-signal circuits |
| Start-Up Time | 200μs - allows rapid power sequencing in multi-rail systems without timing bottlenecks |
| Thermal Shutdown | 145°C junction threshold - protects against sustained overload in enclosed enclosures |
| Input Voltage Range | 2.0V to 6.0V - accommodates wide input sources including USB, Li-ion, and buck converter outputs |
Pinout & Package
SOT89-3 (Y Package) with exposed thermal pad on pin 3 (IN), providing 133°C/W junction-to-ambient thermal resistance when mounted per recommended PCB 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 directly to load rail |
| 2 (GND) | Power ground reference | Low-impedance return path for load current and internal circuitry; ties to thermal pad via PCB copper |
| 3 (IN) | Unregulated input supply | Requires ≥1μF MLCC decoupling; exposed thermal pad enhances heat dissipation and must be soldered to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Low IQ with EN control | 35μA operating current + 0.1μA shutdown current - enables micro-power sleep states in IoT endpoints |
| Stable with 1μF ceramic output cap | No minimum ESR requirement - eliminates need for bulk tantalum or aluminum electrolytic capacitors |
| Fast transient response | ≤20mV undershoot/overshoot during 10mA↔600mA load steps - maintains signal integrity for high-speed digital interfaces |
| Integrated protection | Current limit (1.4A), short-circuit clamp (240mA), and thermal shutdown (145°C) - removes need for external fault management circuitry |
| Wide temperature range | –40°C to +85°C operation - qualified for industrial and automotive cabin applications |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-2802E/TO | 300mA max output, 2μA IQ, SOT23-3 package | Limited to low-current sensors; lacks EN pin and thermal shutdown | Select only for sub-100mA loads where ultra-low IQ outweighs current capability and protection |
| Torex XC6206P282MR-G | 250mA max output, 1.0μA IQ, no EN pin, SOT23-3 | Cannot support FPGA I/O or USB-C aux rails; requires external enable circuitry | Use only in cost-sensitive, low-power consumer wearables with static enable requirements |

FAQ
What is the maximum input voltage for AP7365-28YG-13?
The absolute maximum input voltage is 6.5V, but the recommended operating range is 2.0V to 6.0V. Exceeding 6.0V risks violating safe operating area limits and may trigger thermal shutdown under load due to increased power dissipation (PD = (VIN − 2.8V) × IOUT).
Can AP7365-28YG-13 operate without an output capacitor?
No. A minimum 1μF ceramic output capacitor is required for stability and transient response. Omitting it causes oscillation and voltage overshoot during load steps. The device is optimized for ceramic capacitors with ESR >15mΩ; tantalum or electrolytic types are not recommended.
How does the EN pin behave during power-up?
The EN pin must rise above 1.4V (VIH) to enable regulation. If left floating, internal leakage may cause unpredictable startup behavior. For always-on operation, tie EN directly to IN. Do not connect EN to a weak pull-up; it must drive ≥1μA sink/source current per datasheet specifications.
Is AP7365-28YG-13 qualified for automotive applications?
AP7365-28YG-13 is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., AP7365Q series) with PPAP documentation, IATF 16949 manufacturing, and extended temperature screening. This part is rated for industrial temperature range (–40°C to +85°C) only.
