Product details
Overview
AP7366EA-W5-7 from Diodes Incorporated is a 600mA adjustable/low-dropout linear regulator in SOT25 package, featuring 60μA quiescent current, 300mV dropout at 600mA (VOUT = 3.3V), and 75dB PSRR at 1kHz. It integrates enable control, thermal shutdown, and current limiting, and is designed for battery-powered portable electronics requiring stable low-noise voltage regulation.
For engineers reviewing the AP7366EA-W5-7 datasheet, AP7366EA-W5-7 pinout, AP7366EA-W5-7 application, or AP7366EA-W5-7 equivalent, key selection factors include its ultra-low IQ, fast 150μs startup, compatibility with 1μF ceramic output capacitors, and dual-package availability (SOT25/U-DFN2020-6) across fixed and adjustable output variants.
Technical Context
The AP7366EA-W5-7 implements a PMOS pass transistor architecture enabling low dropout and high PSRR. Its internal 0.8V bandgap reference feeds an error amplifier that regulates output via external resistor divider (adjustable mode) or fixed internal feedback (fixed-output versions).
Enable logic operates with VIH ≥ 1.0V and VIL ≤ 0.3V, supporting direct microcontroller GPIO control. Protection circuitry includes foldback current limiting (typ. 250mA short-circuit clamp), thermal shutdown at +150°C with +20°C hysteresis, and EN pull-down resistor of 3MΩ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 600mA max - supports FPGA I/O rails and DSP core supplies without derating at ambient ≤85°C |
| Quiescent Current | 60μA typ - enables multi-year battery life in always-on IoT sensors and wearables |
| Dropout Voltage | 300mV at 600mA (3.3V out) - allows operation from single-cell Li-ion (3.0V min) with full load |
| PSRR | 75dB at 1kHz - suppresses switching noise from adjacent DC-DC converters in mixed-signal systems |
| Startup Time | 150μs - enables rapid power cycling in processor sleep/wake transitions |
| Input Voltage Range | 2.2V to 6.0V - compatible with USB-powered, coin-cell, and multi-cell battery inputs |
| Thermal Shutdown | +150°C threshold with +20°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking |
Pinout & Package
SOT25 package (3.0mm × 2.8mm × 1.3mm), thermally enhanced with exposed pad (not electrically connected). Pin 1 = IN, Pin 2 = GND, Pin 3 = EN, Pin 4 = NC (no internal connection), Pin 5 = OUT. NC pin must be left floating or tied to GND; does not affect functionality.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Input voltage supply | Bypassed with ≥1μF MLCC; requires low-impedance trace to minimize input ripple and ensure stability |
| GND (Pin 2) | Power ground reference | Primary return path for IN, OUT, and EN; must connect to solid ground plane for thermal and noise performance |
| EN (Pin 3) | Enable control input | Active-high logic interface; VIH ≥ 1.0V ensures reliable turn-on with 1.8V/3.3V MCUs; internal 3MΩ pull-down holds OFF by default |
| NC (Pin 4) | No internal connection | Electrically isolated; may be left unconnected or tied to GND for mechanical stability-no functional impact |
| OUT (Pin 5) | Regulated output voltage | Requires ≥1μF ceramic capacitor to GND; low ESR improves transient response and avoids oscillation |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 60μA typical - reduces standby power loss by >90% vs. legacy LDOs, critical for energy-harvesting nodes |
| Stable with 1μF ceramic output cap | Eliminates need for large tantalum or electrolytic capacitors - saves board space and improves reliability |
| Fast load transient response | ≤20mV undershoot/overshoot for 100mA ↔ 500mA steps - maintains clean supply for RF transceivers and ADCs |
| Adjustable output range | 0.8V–5.0V via external R1/R2 divider - supports custom core voltages without redesigning BOM |
| Integrated protection suite | Current limit + thermal shutdown + short-circuit clamp - removes need for external fault management circuitry |
Applications
| Portable Medical Sensors | FPGA I/O Power Rails |
|---|---|
|
Use Scenario: Continuous glucose monitor with BLE radio and analog front-end operating from CR2032 coin cell. IC Role / Device Role / Timing Role: Primary LDO supplying 1.8V to BLE SoC and 3.3V to sensor signal chain. Use Value: 60μA IQ extends battery life beyond 2 years; 150μs startup synchronizes with BLE advertising intervals. |
Use Scenario: Industrial PLC module using Xilinx Spartan FPGA with configurable I/O banks. IC Role / Device Role / Timing Role: Dedicated LDO per I/O bank (1.2V, 1.8V, 2.5V, 3.3V) for noise isolation and rail sequencing. Use Value: 75dB PSRR rejects noise from adjacent DC-DC converters; 600mA rating handles burst I/O switching currents. |
| Wearable Fitness Tracker | Automotive Infotainment MCU Core |
|
Use Scenario: Arm Cortex-M4-based activity tracker with optical heart-rate sensor and OLED display. IC Role / Device Role / Timing Role: Adjustable 1.1V core LDO for MCU, enabled only during active sensing cycles. Use Value: EN pin controlled by MCU GPIO enables dynamic power gating; 300mV dropout sustains regulation down to 2.5V battery voltage. |
Use Scenario: Head unit application processor (e.g., NXP i.MX8) requiring clean 1.0V core supply in temperature-cycled cabin environment. IC Role / Device Role / Timing Role: Secondary LDO post-regulating switched-mode supply for noise-sensitive CPU core. Use Value: -40°C to +85°C ambient rating meets automotive grade requirements; thermal shutdown prevents latch-up during hot-soak conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-IQ LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-3302E/MB | 300mA output, 2.0μA IQ, 600mV dropout at 250mA - lower IQ but halved current capability | Best for ultra-low-power sensor nodes where <300mA load suffices; unsuitable for FPGA I/O or multi-rail systems | Select when battery life dominates over current capacity; verify thermal margin at 85°C ambient |
| TPL7407LPGF | 500mA output, 25μA IQ, 400mV dropout at 500mA - slightly lower IQ but higher dropout and no adjustable version | Optimized for industrial PLCs with fixed 3.3V/5V rails; lacks ADJ pin for custom voltages | Choose for cost-sensitive fixed-voltage designs where 500mA is sufficient and 25μA IQ justifies trade-off in dropout |
Compared with MCP1703T-3302E/MB and TPL7407LPGF, the AP7366EA-W5-7 uniquely balances 600mA drive, 60μA IQ, and 0.8–5.0V adjustability - making it the only option among the three capable of powering FPGA I/O banks while maintaining sub-100μA standby in portable systems.

FAQ
What is the minimum output capacitor required for stability?
The AP7366EA-W5-7 is stable with a minimum 1μF ceramic capacitor on the output. This value ensures adequate phase margin across all operating conditions, including full 600mA load and -40°C to +85°C ambient. Larger capacitance improves transient response but is not required for basic stability.
Can the EN pin be left unconnected?
No - the EN pin must not be left floating. It has an internal 3MΩ pull-down resistor, so leaving it unconnected results in guaranteed disable state. For always-on operation, tie EN directly to IN. For MCU-controlled enable, drive with a GPIO meeting VIH ≥ 1.0V and VIL ≤ 0.3V.
Is the AP7366EA-W5-7 qualified for automotive use?
The AP7366EA-W5-7 itself is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., AP7366Q series) with PPAP documentation, IATF 16949 manufacturing, and extended temperature screening. For automotive designs, contact Diodes' automotive sales team for qualified alternatives.
How does the adjustable version set output voltage?
Output voltage is set using two external resistors: VOUT = 0.8V × (1 + R1/R2), where R2 connects between ADJ and GND, and R1 connects between OUT and ADJ. R2 must be ≤80kΩ to maintain reference stability; typical values are R2 = 100kΩ and R1 = 100kΩ for 1.6V output.
