Product details
Overview
AP7365-12WG-7 from Diodes Incorporated is a fixed-output 1.2V, 600mA low-dropout linear regulator with enable control, 35μA quiescent current, 300mV dropout at full load, and stable operation with 1μF ceramic output capacitance. It serves as a primary power supply for FPGA I/O rails and DSP core domains in portable computing systems where battery life and transient response are critical.
For engineers reviewing the AP7365-12WG-7 datasheet, AP7365-12WG-7 pinout, AP7365-12WG-7 application, or AP7365-12WG-7 equivalent, key selection criteria include dropout voltage under 600mA load, PSRR performance at 1kHz, thermal shutdown threshold, EN logic-level compatibility, and SOT25 package thermal resistance for board-level power integrity.
Technical Context
The AP7365-12WG-7 implements a PMOS pass transistor architecture with internal 0.8V bandgap reference and error amplifier, enabling precise 1.2V regulation across -40°C to +85°C ambient. Its fast 200μs start-up time and excellent load transient response stem from optimized internal compensation and low-output-impedance design.
It integrates current-limit protection (1.4A typical), short-circuit current limiting (240mA), and thermal shutdown activation at +145°C with +15°C hysteresis. The EN pin accepts logic-high signals ≥1.4V to activate regulation and logic-low ≤0.4V to enter shutdown mode with 0.1μA leakage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2V ±2% over temperature and load; enables direct powering of 1.2V FPGA I/O banks without external feedback resistors. |
| Max Output Current | 600mA continuous; supports high-current digital loads such as multi-lane SerDes interfaces or memory buffers. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥ 2.5V); allows operation from 1.5V input - critical for single-cell Li-ion or Li-poly backup supplies. |
| Quiescent Current | 35μA typical at zero load; 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 rail. |
| Start-Up Time | 200μs typical; enables rapid power sequencing in multi-rail systems without violating processor reset timing requirements. |
| Thermal Shutdown | Triggers at +145°C junction temperature with +15°C hysteresis; prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
SOT25 (W package) - 5-pin surface-mount package with exposed thermal pad on bottom side; θJA = 169°C/W on standard FR-4 board; footprint compatible with JEDEC MO-178AB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input voltage supply | Accepts 2V–6V input; requires ≥1μF MLCC bypass capacitor placed adjacent to pin to suppress high-frequency noise and ensure stability. |
| 2 - GND | Power ground reference | Primary return path for load current and internal bias; must connect directly to low-impedance ground plane to minimize noise coupling. |
| 3 - EN | Enable control input | Active-high logic interface; drives internal pass transistor gate; tied to IN if always-on operation is required. |
| 4 - NC | No connection | Internally unconnected; must remain floating or grounded per layout guidelines - no external circuitry allowed. |
| 5 - OUT | Regulated output voltage | Delivers stable 1.2V to load; requires ≥1μF ceramic capacitor with ESR >15mΩ placed within 2mm of pin for transient stability. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout operation | 300mV at 600mA enables use with 1.5V input sources - essential for ultra-low-voltage battery-powered applications. |
| Ultra-low IQ | 35μA quiescent current extends battery runtime in sleep modes without compromising start-up speed or regulation accuracy. |
| Fast transient response | Stable output under 10mA ↔ 600mA load steps with <20mV undershoot/overshoot - meets GSM/EDGE baseband power requirements. |
| Integrated protection | Current limit (1.4A), short-circuit clamp (240mA), and thermal shutdown (+145°C) eliminate need for external fault management circuitry. |
| Small-footprint packaging | SOT25 (2.9mm × 2.8mm) provides high power density with accessible pins for manual rework and automated optical inspection. |
Applications

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 |
|---|---|---|---|
| AP7361-12YG-13 | SOT89-3 package; higher θJA (133°C/W); no EN pin; same 1.2V/600mA spec | Limited to space-constrained designs where thermal pad access is impractical; unsuitable for sequenced power systems | Select when board layout prohibits SOT25 mounting or EN functionality is unnecessary |
| MCP1703T-1202E/MB | Microchip part; 250mV dropout at 250mA; 4μA IQ; only 250mA rated; SOT23-5 | Lower current capacity and different thermal profile; better for sub-200mA always-on sensors | Choose only for ultra-low-IQ, low-current roles - not a functional replacement for 600mA loads |
Compared with AP7365-12WG-7, AP7361-12YG-13 trades enable control and superior thermal performance for larger footprint and fixed mounting orientation, while MCP1703T-1202E/MB offers lower IQ but cannot sustain 600mA loads or match transient response - making AP7365-12WG-7 the sole fit for high-current, fast-dynamic FPGA/DSP applications.

FAQ
What is the minimum input voltage required for stable 1.2V output at 600mA?
The AP7365-12WG-7 requires a minimum input voltage of 1.5V to maintain regulation at 600mA load, based on its 300mV dropout specification. Below this, output voltage collapses linearly; operation below 2.0V input is outside recommended conditions per datasheet Section 6.2.
Can the EN pin be left unconnected in always-on applications?
No - the EN pin must be actively driven high (≥1.4V) or tied directly to the IN pin. Leaving it floating risks undefined behavior due to internal leakage paths; the datasheet explicitly states that unused EN pins should be connected to IN for guaranteed turn-on operation.
Is a minimum load required for output stability?
No minimum load is required. The AP7365-12WG-7 remains stable and fully regulated from zero load to 600mA, as confirmed in Section 9.2 of the datasheet. This eliminates need for dummy loads in low-power sleep states.
What is the maximum allowable PCB copper area for the thermal pad in SOT25?
The thermal pad (pin 4, NC) has no electrical function but serves as a thermal conduction path. Diodes recommends a minimum 25mm² exposed copper area with 4–6 thermal vias (0.3mm diameter) to inner ground planes to achieve the specified θJA of 169°C/W - exceeding this improves thermal margin but is not strictly limited.
