Product details
Overview
AP7365-28ERG-13 from Diodes Incorporated is a fixed-output 2.8V, 600mA low-dropout linear regulator with enable control, 35μA quiescent current, and 300mV dropout at full load. It integrates thermal shutdown, current limiting, and short-circuit protection, and is optimized for FPGA I/O power, battery-powered portable devices, and low-power embedded systems requiring stable voltage under fast load transients.
For engineers reviewing the AP7365-28ERG-13 datasheet, AP7365-28ERG-13 pinout, AP7365-28ERG-13 application, or AP7365-28ERG-13 equivalent, key selection criteria include its 2.8V fixed output, SOT223-ER package thermal performance (θJA = 142°C/W), EN pin logic thresholds (VIH = 1.4V, VIL = 0.4V), and stability with 1μF ceramic output capacitance.
Technical Context
The AP7365-28ERG-13 implements a PMOS pass transistor architecture enabling ultra-low dropout (300mV @ 600mA) and high PSRR (65dB @ 1kHz). Its internal 0.8V bandgap reference and error amplifier deliver ±2% output accuracy across –40°C to +85°C ambient.
Enable functionality uses active-high logic with 1μA max input current; thermal shutdown activates at +145°C with +15°C hysteresis. The device operates stably without minimum load and supports fast 200μs startup from EN assertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8V ±2% over –40°C to +85°C - ensures precise core/I/O rail compliance for 2.8V logic interfaces. |
| Max Output Current | 600mA continuous - sufficient for powering multiple low-power peripherals or FPGA I/O banks. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥ 2.5V) - enables operation down to 3.1V input, extending battery runtime in single-cell Li-ion systems. |
| Quiescent Current | 35μA typical - minimizes standby power loss in always-on subsystems like real-time clocks or sensor hubs. |
| PSRR | 65dB at 1kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Start-Up Time | 200μs - supports rapid wake-up from deep-sleep modes in portable applications. |
| Thermal Shutdown | +145°C activation with +15°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
SOT223-ER package with exposed thermal pad (pin 3 = GND/TAB); compact 3-pin footprint optimized for thermal dissipation in space-constrained industrial and portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Input voltage supply | Accepts 2V–6V; requires ≥1μF ceramic bypass capacitor placed adjacent to pin to suppress input ripple and ensure stability. |
| GND/TAB (Pin 2) | Ground reference and thermal path | Internal connection to exposed thermal pad; must be soldered to large copper pour for θJA = 142°C/W performance. |
| OUT (Pin 3) | Regulated output | Delivers fixed 2.8V; requires ≥1μF ceramic output capacitor with ESR >15mΩ for guaranteed stability. |
| EN (Pin ?) | Enable control input | Not present on SOT223-ER fixed-output variant - permanently tied high internally; no external enable function. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout operation | 300mV @ 600mA enables use with 3.1V minimum input - critical for single-cell Li-ion (3.0–4.2V) and USB-powered systems. |
| Ultra-low IQ | 35μA quiescent current reduces no-load power loss to <105μW at 3V input - extends shelf life in battery-backed IoT nodes. |
| Fast transient response | Stable 20mV output deviation during 10mA↔600mA load steps - maintains clean supply for GSM baseband and DSP cores. |
| Integrated protection | Current limit (~1.4A), short-circuit clamp (~240mA), and thermal shutdown prevent field failures in unattended equipment. |
| Small-footprint stability | Guaranteed stability with 1μF ceramic output capacitor - eliminates need for bulky tantalum or electrolytic caps. |
Applications
| Portable Medical Sensors | FPGA I/O Power |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-2802E/TO | 300mA output, 2μA IQ, SOT23-5 package - lower current, far lower IQ, no thermal pad. | Only suitable for ultra-low-power sub-300mA loads; lacks thermal robustness for sustained 600mA operation. | Select only when load current ≤300mA and IQ <5μA is mandatory; not a drop-in replacement. |
| TPS7A0528PDBVR | 200mA output, 25μA IQ, 170mV dropout @ 200mA, SOT23-5 - smaller package but 1/3 current capacity. | Inadequate for FPGA I/O or multi-sensor loads requiring >300mA; better for single-rail MCU peripherals. | Choose if board space is critical and load is ≤200mA; requires redesign of output capacitance and thermal layout. |
Compared with MCP1700-2802E/TO and TPS7A0528PDBVR, the AP7365-28ERG-13 uniquely delivers 600mA output in a thermally enhanced SOT223 package while maintaining 35μA IQ - making it the only viable option for compact, high-current 2.8V point-of-load regulation where thermal margin and current headroom are non-negotiable.

FAQ
Is the EN pin accessible on the AP7365-28ERG-13?
No. The AP7365-28ERG-13 uses the SOT223-ER package configured for fixed-output operation, where the EN function is internally tied high. Enable control is only available on SOT25 and U-DFN2020-6 variants (e.g., AP7365-28WG-7 or AP7365-28SNG-7).
What is the minimum recommended output capacitance for stability?
A 1μF X5R/X7R ceramic capacitor with ESR ≥15mΩ is the minimum required for guaranteed stability. Larger values (e.g., 2.2μF–10μF) further improve load transient response and reduce output ripple, especially under dynamic FPGA I/O switching.
Can AP7365-28ERG-13 operate from a 2.5V input?
No. With a 2.8V output and 300mV typical dropout, the minimum valid input is 3.1V. At 2.5V input, the device enters dropout and cannot regulate - output collapses to ~2.2V. Input must be ≥3.1V for full 600mA capability.
Does this part require an external feedback resistor network?
No. The AP7365-28ERG-13 is a fixed-output variant; the 2.8V regulation is achieved via internal resistor divider. External resistors are only required for adjustable versions (e.g., AP7365-ADJ in SOT25 or U-DFN2020-6 packages).
