Product details
Overview
AP7365-28SNG-7 from Diodes Incorporated is a fixed-output 2.8V, 600mA low-dropout linear regulator with 35μA quiescent current, 300mV dropout at full load, and integrated enable control. It operates from 2V–6V input, delivers stable output with only 1μF ceramic capacitor, and features thermal shutdown, current limiting, and fast 200μs startup-ideal for FPGA I/O rails and battery-powered portable electronics.
For engineers reviewing the AP7365-28SNG-7 datasheet, AP7365-28SNG-7 pinout, AP7365-28SNG-7 application, or AP7365-28SNG-7 equivalent, key selection criteria include dropout voltage at 600mA, PSRR performance at 1kHz, EN logic thresholds, thermal resistance in U-DFN2020-6, and compatibility with low-ESR ceramic output capacitors.
Technical Context
The AP7365-28SNG-7 implements a PMOS pass transistor architecture enabling ultra-low dropout (300mV @ 600mA) and near-zero gate drive current, directly contributing to its 35μA quiescent consumption. Its internal 0.8V bandgap reference and error amplifier support precise 2.8V output regulation across –40°C to +85°C ambient.
Fast transient response is achieved via optimized internal compensation and low-output-impedance design, maintaining ±20mV output deviation during 10mA→600mA load steps. The EN pin accepts 1.4V VIH and tolerates 0.4V VIL, enabling direct interfacing with 1.8V/3.3V logic without level shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8V ±2% over temperature and load - ensures reliable core/I/O rail compliance for 2.8V ASICs and sensors. |
| Max Output Current | 600mA continuous - supports moderate-power FPGA I/O banks and microcontroller peripherals without external boost. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥ 2.5V) - enables operation down to VIN = 3.1V, extending usable battery range in single-cell Li-ion systems. |
| Quiescent Current | 35μA typical - minimizes no-load power loss, critical for always-on subsystems in wearables and IoT edge nodes. |
| PSRR | 65dB at 1kHz - suppresses switching noise from upstream DC-DC converters, preserving signal integrity in analog sensor interfaces. |
| Start-Up Time | 200μs - allows rapid power sequencing in multi-rail systems and low-latency wake-from-standby in portable devices. |
| Thermal Shutdown | Triggers at +145°C with +15°C hysteresis - provides robust fault protection during sustained overload or poor PCB heatsinking. |
Pinout & Package
AP7365-28SNG-7 is housed in a 2.0mm × 2.0mm, 0.65mm height U-DFN2020-6 package with exposed thermal pad (SN package code), rated at θJA = 132°C/W on standard FR-4 board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 3) | Input voltage supply | Accepts 2V–6V; requires ≥1μF ceramic bypass to GND placed adjacent to pin for noise immunity and stability. |
| GND (Pin 2) | Power ground reference | Common return path for IN, OUT, and EN; must connect directly to thermal pad for optimal thermal performance. |
| EN (Pin 1) | Enable control input | Active-high logic interface (VIH ≥ 1.4V); tie to IN for always-on operation; floating not permitted. |
| OUT (Pin 4) | Regulated output | Delivers 2.8V ±2%; requires ≥1μF ceramic capacitor (ESR > 15mΩ) placed within 2mm of pin for transient stability. |
| ADJ (Pin 6) | Feedback reference node | No connection in fixed-output variant; internally tied to 0.8V reference - unused and must remain unconnected. |
| NC (Pin 5) | No connection | Electrically isolated terminal; no internal bond wire - leave unconnected and unpopulated on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ operation | 35μA quiescent current enables >1-year battery life in coin-cell–powered remote sensors with 10μA average system load. |
| Single-capacitor stability | Stable with 1μF ceramic output capacitor (ESR > 15mΩ) - eliminates need for costly tantalum or polymer caps and simplifies BOM. |
| Fast load transient recovery | ≤20mV undershoot/overshoot during 10mA↔600mA step loads - maintains clean power for high-speed digital interfaces like SPI and I²C. |
| Integrated protection suite | Combines current limit (~1.4A), short-circuit clamp (~240mA), and thermal shutdown (+145°C) - removes need for external fault management circuitry. |
| Wide input voltage range | 2V–6V operation supports direct regulation from single Li-ion (2.7–4.2V), USB (4.75–5.25V), or dual alkaline cells (up to 3.2V). |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-quiescent-current LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-2802E/TO | 300mA max output, 2μA IQ, SOT23-5 package, higher dropout (600mV @ 250mA) | Limited to ultra-low-power sensors; insufficient for FPGA I/O or burst-mode MCU cores | Select only when IQ < 5μA is mandatory and load ≤300mA - tradeoff is reduced current capability and slower transient response. |
| Torex XC6210B282MR-G | 500mA max output, 15μA IQ, 250mV dropout @ 500mA, same U-DFN2020-6 footprint | Slightly lower current rating and narrower input range (1.5V–6.0V) - marginal for 2.8V operation near 3.1V VIN minimum | Prefer for space-constrained designs needing lowest possible IQ; verify VIN margin at 600mA load due to 500mA rating limit. |
Compared with MCP1700-2802E/TO and XC6210B282MR-G, AP7365-28SNG-7 uniquely balances 600mA delivery, 35μA IQ, and 300mV dropout in a thermally enhanced U-DFN2020-6 package - making it optimal for FPGA I/O and industrial sensor hubs where both current headroom and efficiency matter.

FAQ
What is the minimum input voltage required for AP7365-28SNG-7 to maintain regulation at 600mA load?
The AP7365-28SNG-7 requires VIN ≥ 3.1V to sustain 2.8V output under 600mA load, based on its 300mV dropout specification at that current. Below 3.1V, output voltage drops linearly with input; operation below 2.0V is prohibited per absolute maximum ratings.
Can AP7365-28SNG-7 operate without an output capacitor?
No. A minimum 1μF ceramic output capacitor with ESR > 15mΩ is mandatory for stability, as confirmed in the datasheet's Application Information section. Omitting it causes oscillation and potential device failure under load transients.
Is the EN pin internally pulled up or down?
The EN pin has no internal pull-up or pull-down resistor. It must be actively driven to ≥1.4V for enable or ≤0.4V for disable; leaving it floating risks undefined operation and unintended shutdown or activation.
Does AP7365-28SNG-7 support reverse-voltage protection?
No. The device lacks reverse-battery or reverse-input protection. Applying negative voltage to IN or OUT relative to GND violates absolute maximum ratings and may cause permanent damage. External protection diodes are required in bidirectional power paths.
