Product details
Overview
AP7365-33WG-7 from Diodes Incorporated is a fixed-output 3.3V, 600mA low-dropout linear regulator in SOT25 package with 35μA quiescent current, 300mV dropout at full load, and integrated enable control. It delivers stable power to FPGA I/O rails, notebook CPU cores, and battery-powered consumer electronics requiring fast transient response and ultra-low standby consumption.
For engineers reviewing the AP7365-33WG-7 datasheet, AP7365-33WG-7 pinout, AP7365-33WG-7 application, or AP7365-33WG-7 equivalent, key selection criteria include dropout voltage at 600mA, PSRR at 1kHz, thermal shutdown threshold, EN logic thresholds, and compatibility with 1μF ceramic output capacitors.
Technical Context
The AP7365-33WG-7 integrates a PMOS pass element, bandgap reference, error amplifier, and protection circuitry (current limit, thermal shutdown) in a single die. Its fixed 3.3V output eliminates external feedback resistors, simplifying layout for space-constrained applications.
It operates across 2V–6V input range with guaranteed regulation down to 300mV dropout at 600mA load and maintains stability with ≥1μF ceramic output capacitance and ESR >15mΩ - enabling compact, low-BOM designs without tantalum or electrolytic capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±2% over -40°C to +85°C ambient - ensures reliable logic-level compliance for 3.3V I/O standards. |
| Max Output Current | 600mA continuous - supports mid-power digital loads including FPGA I/O banks and microcontroller peripherals. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥ 2.5V) - enables operation from 3.6V Li-ion batteries down to 3.3V under full load. |
| Quiescent Current | 35μA typical - extends battery life in always-on sensor nodes and standby modes of portable devices. |
| PSRR | 65dB at 1kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Start-Up Time | 200μs - meets real-time wake-up requirements for DSPs and GSM baseband processors. |
| Thermal Shutdown | Triggers at +145°C with +15°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design. |
Pinout & Package
SOT25 (W package) - 5-pin surface-mount package with exposed pad for thermal enhancement; footprint compatible with JEDEC TO-236AB standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: IN | Input voltage supply | Accepts 2V–6V; requires ≥1μF ceramic bypass capacitor placed adjacent to pin to suppress high-frequency noise. |
| 2: GND | Ground reference | Primary return path for input/output currents; must connect directly to low-impedance ground plane. |
| 3: EN | Enable control input | Active-high logic interface (VIH ≥ 1.4V, VIL ≤ 0.4V); tie to IN for always-on operation. |
| 4: NC | No connection | Internally unconnected; must remain floating - no external pull-up/down or routing required. |
| 5: OUT | Regulated output | Delivers 3.3V ±2%; requires ≥1μF ceramic capacitor with ESR >15mΩ placed within 2mm of pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout architecture | 300mV at 600mA enables use with single-cell Li-ion (3.0–4.2V) while maintaining regulation through discharge cycle. |
| Fast transient response | Stable under 10mA ↔ 600mA load steps with <20mV overshoot/undershoot - critical for burst-mode DSP and RF power amplifiers. |
| Ultra-low IQ | 35μA quiescent current reduces no-load power loss to <115μW at 3.3V - ideal for energy-harvesting and coin-cell applications. |
| 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 × 1.6mm) supports high-density PCB layouts in wearables and IoT edge nodes. |
Applications
| FPGA I/O Power Supply | Notebook CPU Core Rail |

IC Role / Device Role / Timing Role: Fast-transient LDO supporting rapid 100μA ↔ 100mA load transitions without brownout. Use Value: 65dB PSRR at 1kHz attenuates switching noise from buck converter feeding the LDO, preserving RF receiver sensitivity. |
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 |
|---|---|---|---|
| MCP1700-3302E/TO | 300mA max output, 2.3μA IQ, SOT23-3 package - lower current, far lower quiescent current, no enable pin. | Suitable only for ultra-low-power sensor nodes; insufficient for FPGA I/O or GSM baseband peak loads. | Select when load never exceeds 300mA and sub-5μA IQ is mandatory; avoid for 600mA or EN-controlled systems. |
| Torex XC6206P332MR-G | 500mA max output, 1.0μA IQ, SOT23-3 - no enable, lower current rating, higher dropout (500mV @ 500mA). | Targeted at coin-cell devices with light loads; cannot sustain 600mA or meet fast transient specs of AP7365. | Choose for cost-sensitive, low-current applications where 500mV dropout and missing EN are acceptable trade-offs. |
Compared with MCP1700-3302E/TO and XC6206P332MR-G, AP7365-33WG-7 uniquely balances 600mA capability, 35μA IQ, 300mV dropout, and active-high EN in a 5-pin SOT25 - making it the only option among the three qualified for FPGA I/O and GSM baseband use cases.

FAQ
What is the minimum input voltage required for AP7365-33WG-7 to maintain regulation at 600mA?
The AP7365-33WG-7 requires VIN ≥ 3.6V to sustain 3.3V output at 600mA, based on its 300mV dropout specification (VOUT + VDROPOUT = 3.3V + 0.3V). Below 3.6V, output voltage drops proportionally - e.g., at VIN = 3.5V, VOUT ≈ 3.2V under full load. Input must also stay within absolute maximum rating of 6.5V.
Can AP7365-33WG-7 operate without an output capacitor?
No. The AP7365-33WG-7 requires a minimum 1μF ceramic output capacitor with ESR >15mΩ for stability, as confirmed in the datasheet's Application Information section. Omitting it causes oscillation and unregulated output. Larger values (e.g., 4.7μF) improve transient response but are not mandatory.
Is the EN pin internally pulled up or down?
The EN pin has no internal pull-up or pull-down resistor. It is a high-impedance CMOS input requiring external bias: tie directly to IN for always-on operation, or drive with a logic signal meeting VIH ≥ 1.4V and VIL ≤ 0.4V. Leaving it floating may cause erratic enable behavior due to noise coupling.
Does AP7365-33WG-7 support reverse polarity protection?
No. The AP7365-33WG-7 lacks reverse-voltage protection. Applying negative voltage to IN or OUT relative to GND violates Absolute Maximum Ratings and may cause permanent damage. External protection (e.g., series Schottky diode on IN) is required in systems prone to reverse battery insertion or back-driving.
