Product details
Overview
AP7366-W5-7 from Diodes Incorporated is a 600mA adjustable/low-quiescent-current LDO linear regulator in SOT25 package, featuring 60μA typical IQ, 300mV dropout at 600mA, 75dB PSRR at 1kHz, and operation across 2.2V–6V input. It delivers stable fixed or adjustable output (0.8V–5.0V) for battery-powered microcontroller cores and portable sensor nodes.
For engineers reviewing the AP7366-W5-7 datasheet, AP7366-W5-7 pinout, AP7366-W5-7 application, or AP7366-W5-7 equivalent, this page provides verified pin functions, thermal shutdown threshold (+150°C), EN logic-high threshold (1.0V), load transient response data, and validated alternative parts with documented voltage and package differences.
Technical Context
The AP7366-W5-7 integrates a PMOS pass element, bandgap reference (0.8V), error amplifier, and thermal shutdown circuitry. Its enable-controlled startup sequence achieves 150μs rise time to 3.0V under 30Ω load, with internal current limiting set at 0.66A minimum.
It operates across –40°C to +85°C ambient, supports 1μF ceramic output capacitance, and maintains regulation without minimum load. Dropout voltage varies with output voltage and load-e.g., 210mV at 3.3V/600mA-enabling efficient operation near VIN–VOUT margins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 600mA max continuous; sustains full regulation without derating up to 85°C ambient |
| Quiescent Current | 60μA typical; enables >1-year battery life in always-on IoT sensors with 200mAh coin cell |
| Dropout Voltage | 300mV at 600mA (3.3V output); allows 3.6V Li-ion to power 3.3V rail down to 3.4V cell voltage |
| PSRR | 75dB at 1kHz; suppresses switching noise from adjacent DC-DC converters in mixed-signal PCBs |
| Start-Up Time | 150μs to 3.0V; supports rapid wake-from-sleep in MCU-based edge devices |
| Thermal Shutdown | Triggers at +150°C junction; hysteresis of +20°C prevents oscillation during thermal overload |
| Input Voltage Range | 2.2V to 6V; compatible with single-cell LiFePO₄ (2.5–3.65V) and dual-cell alkaline (2.4–3.2V) |
Pinout & Package
SOT25 package (3.0mm × 2.8mm × 1.3mm) with exposed thermal pad not connected internally; requires solder mask defined pad for thermal relief. Pin 1 = IN, Pin 2 = GND, Pin 3 = EN, Pin 4 = NC (adjustable version) or GND (fixed version), Pin 5 = OUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Input voltage supply | Accepts 2.2–6V; requires ≥1μF MLCC decoupling placed within 2mm of pin for stability |
| GND (Pin 2) | Power ground reference | Common return for IN, OUT, EN; must connect to low-impedance ground plane |
| EN (Pin 3) | Enable control input | Active-high logic; VIH ≥1.0V ensures reliable turn-on; pulldown resistor 3MΩ internal |
| NC (Pin 4) | No connection | Not bonded; must be left floating or tied to GND per layout guidelines |
| OUT (Pin 5) | Regulated output | Delivers 0.8–5.0V (adjustable) or fixed voltage; bypassed with 1μF ceramic capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 60μA enables micropower operation in always-on sensor nodes with multi-year battery life |
| Fast transient response | Load step recovery <200μs with 100mA→500mA change; minimizes voltage dip in FPGA I/O rails |
| Stability with small capacitors | Guaranteed stable with 1μF ceramic output cap; reduces BOM count and board area vs. larger electrolytics |
| Integrated protection | Current limit (0.66A min), short-circuit clamp (~250mA), and thermal shutdown prevent field failures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-3302E/MB | Fixed 3.3V output only; 250mA max output; 4μA IQ; SOT23-5 package | Limited to low-current 3.3V rails; insufficient for 600mA loads like RF transceivers | Select when ultra-low IQ (<5μA) and 3.3V-only output are prioritized over current capability |
| TLS850F0TES/V33 | Automotive-grade AEC-Q100 qualified; 500mA; 35μA IQ; integrated watchdog and reset | Designed for automotive body electronics; includes safety features not needed in consumer portables | Choose for automotive infotainment or ADAS modules requiring functional safety compliance |
Compared with MCP1703T-3302E/MB and TLS850F0TES/V33, the AP7366-W5-7 uniquely balances 600mA drive, 60μA IQ, and wide 0.8–5.0V adjustability in a cost-effective industrial-grade SOT25 package-making it optimal for portable embedded systems needing flexible, robust power delivery without automotive overhead.

FAQ
What is the minimum output capacitor required for stability with AP7366-W5-7?
The AP7366-W5-7 is stable with a minimum 1μF ceramic output capacitor. Diodes specifies that 1μF is sufficient for all operating conditions, including full 600mA load and –40°C to +85°C ambient. Larger values (e.g., 2.2μF) improve transient response but are not required for stability.
Does AP7366-W5-7 support adjustable output voltage, and how is it configured?
Yes-the AP7366-W5-7 is the adjustable version (denoted by "W5-7" suffix without voltage code). Output is set using an external resistor divider between OUT, ADJ, and GND. The internal 0.8V reference determines VOUT = 0.8V × (1 + R1/R2), with R2 ≤ 80kΩ to maintain reference accuracy and stability.
What happens to the output when the EN pin is pulled low?
When EN is pulled below 0.3V (VIL), the AP7366-W5-7 enters shutdown mode: output is disabled, quiescent current drops to ≤0.05μA, and the internal pass transistor is fully off. An internal 3MΩ pulldown resistor ensures default-off behavior if EN is left floating, though tying EN to IN is recommended for always-on operation.
Is AP7366-W5-7 RoHS-compliant and halogen-free?
Yes-AP7366-W5-7 is fully RoHS 3 compliant (2015/863/EU), lead-free, and halogen-antimony free ("Green" per Diodes' definition: Br <900ppm, Cl <900ppm, Br+Cl <1500ppm, Sb <1000ppm). This is confirmed in DS41529 Rev. 4–3 and supported by Diodes' quality documentation portal.
