Product details
Overview
AP7365-30SNG-7 from Diodes Incorporated is a fixed-output 3.0V, 600mA low-dropout linear regulator in U-DFN2020-6 package, featuring 35μA quiescent current, 300mV dropout at full load, and 65dB PSRR at 1kHz. It integrates enable control, thermal shutdown, and current limiting, and is optimized for battery-powered portable electronics requiring stable low-voltage core/I/O supply.
For engineers reviewing the AP7365-30SNG-7 datasheet, AP7365-30SNG-7 pinout, AP7365-30SNG-7 application, or AP7365-30SNG-7 equivalent, key selection criteria include output voltage accuracy (±2%), fast 200μs startup, stability with 1μF ceramic output capacitor, and thermal performance in space-constrained U-DFN2020-6 layout.
Technical Context
The AP7365-30SNG-7 implements a PMOS pass transistor architecture enabling low dropout (300mV @ 600mA) and ultra-low quiescent current (35μA typ). Its internal 0.8V bandgap reference and error amplifier support precise 3.0V regulation across -40°C to +85°C ambient.
It delivers fast transient response via optimized control loop design-demonstrated by <20mV undershoot/overshoot during 10mA↔600mA load steps-and achieves 65dB PSRR at 1kHz due to high-gain error amplifier and low-noise biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±2% over -40°C to +85°C; enables direct replacement of 3.0V logic rails without external resistors. |
| Max Output Current | 600mA continuous; supports FPGA I/O banks, microcontroller peripherals, and sensor interfaces without derating at TA ≤ 60°C. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥ 2.5V); allows operation from 3.3V input down to 3.0V output with >100mV headroom margin. |
| Quiescent Current | 35μA typical; extends battery life in always-on IoT nodes and wearable standby modes where supply current dominates energy budget. |
| PSRR | 65dB at 1kHz; suppresses switching noise from adjacent DC-DC converters feeding shared input rail. |
| Start-Up Time | 200μs typical; meets real-time wake-up requirements for GSM/TDMA baseband power sequencing. |
| Thermal Shutdown | Triggers at +145°C junction temperature with +15°C hysteresis; prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
AP7365-30SNG-7 uses the U-DFN2020-6 (SN) package: 2.0mm × 2.0mm, 0.5mm pitch, exposed thermal pad (pin 3 = GND). The package supports high-density routing and efficient heat dissipation via bottom-side thermal pad soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 3) | Input voltage supply | Accepts 2V–6V; requires ≥1μF ceramic bypass capacitor placed adjacent to pin to suppress input ripple and ensure stability. |
| GND (Pin 2) | Ground reference | Common return path for IN, OUT, EN, and thermal pad; must be low-impedance plane connected directly to thermal pad for thermal performance. |
| EN (Pin 1) | Enable control input | Active-high logic interface (VIH ≥ 1.4V); ties to IN for always-on operation or connects to MCU GPIO for dynamic power gating. |
| OUT (Pin 4) | Regulated output | Delivers stable 3.0V; requires ≥1μF ceramic capacitor with ESR >15mΩ placed within 2mm of pin for transient stability. |
| ADJ (Pin 6) | Reference feedback node | No connection in fixed-output variant; internally tied to 0.8V reference; must remain unconnected and un-bypassed. |
| NC (Pin 5) | No connect | Unused terminal; electrically isolated and not bonded; may be left floating or grounded per PCB layout convenience. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout with PMOS pass element | 300mV @ 600mA enables 3.3V-to-3.0V conversion with minimal power loss and thermal rise in compact layouts. |
| Stable with 1μF ceramic output cap | Eliminates need for large tantalum or aluminum electrolytics, reducing BOM cost and board area while improving reliability. |
| Fast 200μs start-up time | Supports rapid power cycling in battery-powered devices, minimizing idle time during MCU wake-from-sleep sequences. |
| Integrated protection suite | Combines current limit (~1.4A), short-circuit clamp (~240mA), and thermal shutdown (+145°C) to prevent field failures under fault conditions. |
| High PSRR at 1kHz | 65dB attenuation of DC-DC switching noise ensures clean 3.0V supply for noise-sensitive analog circuits and RF front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP7361-30SNG-7 | 300mA output current, identical 3.0V fixed output, same U-DFN2020-6 package and 35μA IQ. | Lower current capacity limits use to low-power peripherals only (e.g., sensors, RTCs), not FPGA I/O or USB controllers. | Select when load current remains ≤300mA and footprint compatibility is required; reduces cost where full 600mA is unnecessary. |
| MCP1700-3002E/MB | 250mA output, 6μA IQ, SOT-23-3 package; lacks EN pin and thermal shutdown. | Targeted at ultra-low-power always-on functions (e.g., real-time clocks), not dynamic-load applications requiring fast transient response. | Choose only for static, sub-250mA loads where minimal IQ outweighs missing protection and enable features. |
Compared with AP7361-30SNG-7 and MCP1700-3002E/MB, AP7365-30SNG-7 uniquely balances 600mA drive, 35μA IQ, integrated EN control, and full fault protection in a 2mm×2mm footprint-making it optimal for space-constrained, dynamically loaded 3.0V systems.

FAQ
What is the minimum input voltage required for AP7365-30SNG-7 to regulate 3.0V output?
The AP7365-30SNG-7 requires a minimum input voltage of 3.3V to maintain regulation at 3.0V output under full 600mA load, based on its 300mV dropout specification. At lighter loads, input can drop to 3.05V (3.0V + 50mV), but design margin should retain ≥3.3V input for reliable operation across temperature and tolerance.
Can AP7365-30SNG-7 operate without an output capacitor?
No. The AP7365-30SNG-7 requires a minimum 1μF ceramic output capacitor with ESR >15mΩ for stability, as confirmed in the datasheet's Application Information section. Omitting it risks oscillation, excessive overshoot/undershoot during load transients, and potential thermal shutdown under dynamic conditions.
Is the EN pin internally pulled up or does it require external biasing?
The EN pin has no internal pull-up; it is a high-impedance CMOS input requiring explicit logic-level drive. To enable the device permanently, tie EN directly to IN. For controlled sequencing, drive EN with a GPIO capable of delivering ≥1.4V (VIH) and sinking ≤0.4V (VIL) per datasheet thresholds.
How does thermal performance differ between U-DFN2020-6 and SOT25 packages?
The U-DFN2020-6 (SN) package has θJA = 132°C/W, while SOT25 (W) is 169°C/W-meaning the SN package dissipates heat ~22% more efficiently under identical PCB layout. This allows AP7365-30SNG-7 to sustain higher ambient temperatures or load currents before triggering thermal shutdown compared to the SOT25 variant.
