Product details
Overview
AP7365-WG-7 from Diodes Incorporated is a 600mA, fixed-output (3.3V), low-dropout linear regulator in SOT25 package with 35μA quiescent current, 300mV dropout at full load, and active-high 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-WG-7 datasheet, AP7365-WG-7 pinout, AP7365-WG-7 application, or AP7365-WG-7 equivalent, key selection criteria include its 2V–6V input range, ±2% output accuracy over –40°C to +85°C, 65dB PSRR at 1kHz, 200μs startup time, and compatibility with 1μF ceramic output capacitors.
Technical Context
The AP7365-WG-7 implements a PMOS pass transistor architecture enabling low dropout (300mV @ 600mA for VOUT ≥ 2.5V) and high PSRR (65dB @ 1kHz). Its internal 0.8V bandgap reference and error amplifier support precise output regulation across line, load, and temperature variations.
It integrates EN-controlled startup, thermal shutdown (145°C trip, 15°C hysteresis), current limiting (1.4A typical), and short-circuit protection (240mA clamp). The device operates stably with 1μF ceramic output capacitance and requires no minimum load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±2% over –40°C to +85°C - ensures reliable logic-level compliance for 3.3V I/O domains. |
| Max Output Current | 600mA continuous - supports mid-power digital loads like FPGA I/O banks or microcontroller peripherals. |
| Quiescent Current | 35μA typical - enables multi-year battery life in always-on sensor nodes and portable devices. |
| Dropout Voltage | 300mV at 600mA (VOUT ≥ 2.5V) - allows operation down to VIN = 3.6V while maintaining regulation. |
| PSRR | 65dB at 1kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Startup Time | 200μs - enables rapid wake-up from deep-sleep states in real-time embedded systems. |
| Input Voltage Range | 2.0V to 6.0V - compatible with single-cell Li-ion (3.0–4.2V), dual-cell alkaline (2.4–3.2V), and 5V rail inputs. |
Pinout & Package
SOT25 (W package) - 5-pin surface-mount package with exposed pad thermal path; footprint optimized for compact PCB layouts and moderate power dissipation (θJA = 169°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: IN | Input voltage supply | Accepts 2V–6V; requires ≥1μF ceramic bypass capacitor placed adjacent to pin for stability and noise rejection. |
| 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); tie to IN if always-on operation is required. |
| 4: NC | No connection | Internally unconnected; must remain floating or grounded per layout best practice - no external circuitry. |
| 5: OUT | Regulated output | Delivers 3.3V ±2%; requires ≥1μF ceramic capacitor with ESR >15mΩ placed adjacent to pin for transient stability. |
Key Features
| Feature | Design Value |
|---|---|
| Low-IQ operation | 35μA IQ enables >10-year battery life in coin-cell–powered IoT endpoints with 10μA average system load. |
| Fast transient response | Stable 3.3V output under 10mA ↔ 600mA load steps - critical for GSM/TDMA baseband power integrity. |
| Ultra-fast startup | 200μs enable-to-regulation time - supports dynamic power gating in DSP-intensive portable applications. |
| Integrated protection | Thermal shutdown (145°C), current limit (1.4A), and short-circuit clamp (240mA) eliminate need for external fault management circuitry. |
| Capacitor flexibility | Stable with 1μF ceramic output capacitor - reduces BOM count and board area vs. legacy LDOs requiring ≥10μF tantalum. |
Applications
| FPGA I/O Power Supply | Notebook CPU Core Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-3302E/TO | 300mA max output, 2.0μA IQ, SOT23-3 - lower current, far lower IQ, no enable pin. | Suitable only for sub-300mA always-on sensors; lacks EN control and fast transient capability. | Select when ultra-low IQ dominates over output current and dynamic performance requirements. |
| TLS850F3TAV50 | Automotive-grade (AEC-Q100), 500mA, 40μA IQ, integrated watchdog - higher reliability, no adjustable option. | Qualified for automotive infotainment and ADAS modules; adds system monitoring not needed in consumer designs. | Select only for automotive production where AEC-Q100 qualification and functional safety features are mandatory. |
Compared with MCP1700-3302E/TO and TLS850F3TAV50, the AP7365-WG-7 uniquely balances 600mA output, 35μA IQ, 200μs startup, and EN control in a cost-effective industrial-qualified package - making it optimal for portable computing and communications where performance and efficiency are co-prioritized.

FAQ
What is the maximum input voltage for AP7365-WG-7?
The absolute maximum input voltage is 6.5V, but the recommended operating range is 2.0V to 6.0V. Exceeding 6.0V risks violating the 0.3V headroom limit relative to EN and OUT pins and may trigger internal protection or reduce reliability. Operation at 6.0V is validated for all electrical parameters including dropout and PSRR.
Can AP7365-WG-7 operate without an output capacitor?
No - the AP7365-WG-7 requires a minimum 1μF ceramic output capacitor with ESR >15mΩ for stability. Omitting it causes oscillation and output voltage collapse under load. The datasheet explicitly states "output capacitor is required to stabilize and improve transient response" and confirms instability occurs below this threshold in the COUT–ESR vs. load current plot.
Is the EN pin 5V-tolerant when VIN = 3.3V?
Yes - the EN pin accepts logic-high signals up to VIN + 0.3V, so with VIN = 3.3V, EN can safely tolerate up to 3.6V. This allows direct interfacing with 3.3V GPIOs without level-shifting. VIH is specified as ≥1.4V, ensuring compatibility with standard CMOS logic families across temperature.
Does AP7365-WG-7 require a minimum load current for regulation?
No - the device remains stable and fully regulated with zero load current. The datasheet confirms "no minimum load is required to keep the device stable" and specifies that output voltage accuracy (±2%) and line/load regulation are guaranteed from 0mA to 600mA, including no-load conditions.
