Product details
Overview
AP7366EA-12W5-7 from Diodes Incorporated is a 600mA fixed-output low-dropout linear regulator with 1.2V output, 60μA quiescent current, 300mV dropout at full load, and enable control. It operates from 2.2V to 6V input and delivers stable power to FPGA I/O rails, DSP cores, and battery-powered portable electronics requiring high PSRR (75dB @ 1kHz) and fast transient response.
For engineers reviewing the AP7366EA-12W5-7 datasheet, AP7366EA-12W5-7 pinout, AP7366EA-12W5-7 application, or AP7366EA-12W5-7 equivalent, this device supports precise low-noise biasing in space-constrained embedded systems where thermal shutdown protection, current limiting, and ceramic capacitor compatibility (≥1μF) are critical selection criteria.
Technical Context
The AP7366EA-12W5-7 integrates a PMOS pass element, bandgap reference, error amplifier, and thermal shutdown circuitry. Its EN pin enables logic-level on/off control with 1.0V VIH threshold and 3MΩ internal pull-down resistor.
It achieves 75dB PSRR at 1kHz and exhibits excellent line/load transient response due to its fast 150μs startup time and stability with low-ESR 1μF ceramic output capacitors - no minimum load required for regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2V ±1% accuracy ensures reliable core voltage for low-power microcontrollers and FPGA I/O banks. |
| Max Output Current | 600mA continuous delivery supports moderate-power digital subsystems without external current boosting. |
| Quiescent Current | 60μA typical enables >1-year battery life in always-on sensor nodes powered by coin cells. |
| Dropout Voltage | 300mV at 600mA allows operation down to VIN = 1.5V, extending usable battery range in single-cell Li-ion or alkaline systems. |
| PSRR | 75dB at 1kHz suppresses switching noise from adjacent DC/DC converters feeding mixed-signal SoCs. |
| Startup Time | 150μs enables rapid wake-up from deep sleep modes in portable devices without compromising IQ efficiency. |
| Thermal Shutdown | Triggers at +150°C with +20°C hysteresis, preventing permanent damage during sustained overload or poor PCB thermal design. |
Pinout & Package
SOT25 package (3.0mm × 2.8mm × 1.3mm), thermally enhanced with exposed pad not connected internally; requires solder mask defined thermal land for optimal θJA = 139°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input voltage supply | Bypassed with ≥1μF MLCC; must be routed with low-inductance trace to minimize input ripple coupling. |
| 2 - GND | Power ground reference | Shared return path for IN, OUT, and EN; requires low-impedance connection to system ground plane. |
| 3 - EN | Enable control input | Active-high logic interface (VIH ≥1.0V); internal 3MΩ pull-down ensures default OFF state if left unconnected. |
| 4 - NC | No internal connection | Floating or grounded - no electrical impact; may be used as mechanical anchor or thermal relief pad. |
| 5 - OUT | Regulated output | Delivers 1.2V ±1%; bypassed with ≥1μF ceramic capacitor placed adjacent to pin for transient stability. |
Key Features
| Feature | Design Value |
|---|---|
| Low-IQ operation | 60μA quiescent current enables multi-year operation in energy-harvesting and IoT endpoint designs. |
| Fast transient response | Stabilizes within <200μs after 100mA–500mA load steps, minimizing voltage droop in burst-mode processors. |
| Ceramic capacitor compatible | Stable with ≥1μF X5R/X7R MLCCs - eliminates need for costly tantalum or electrolytic output caps. |
| Integrated protection | Current limit (~1A), short-circuit clamp (~250mA), and thermal shutdown prevent field failures under fault conditions. |
| Wide input range | 2.2V–6V operation supports direct connection to USB, Li-ion, and multi-cell alkaline sources without pre-regulation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-IQ LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1202E/MB | 300mA max output, 1.8μA IQ, SOT23-5 package, no EN pin | Limited to ultra-low-current peripherals; lacks enable control and thermal shutdown | Select only when load ≤300mA and always-on operation is acceptable |
| Torex XC6210B122MR-G | 500mA max output, 1.0μA IQ, 200mV dropout at 300mA, SOT25 | Lower IQ but reduced current capability and no integrated short-circuit clamp | Prefer for sub-500mA battery apps prioritizing minimal leakage over robust fault protection |
Compared with MCP1700T-1202E/MB and XC6210B122MR-G, the AP7366EA-12W5-7 uniquely balances 600mA drive, 60μA IQ, EN control, and full fault protection - making it optimal for mid-power portable systems needing both efficiency and reliability.

FAQ
What is the maximum input voltage for AP7366EA-12W5-7?
The absolute maximum input voltage is 6.5V, but recommended operating range is 2.2V to 6.0V. Exceeding 6.0V risks exceeding thermal limits under load, especially in SOT25 packages with higher θJA (139°C/W). Operation above 6.0V is not guaranteed per datasheet specifications and may trigger premature thermal shutdown.
Can AP7366EA-12W5-7 operate without an output capacitor?
No - a minimum 1μF ceramic output capacitor is mandatory for stability and transient performance. The device is not stable without it, and omitting the capacitor causes oscillation, excessive output ripple, and potential damage during load transients. The capacitor must be placed within 2mm of the OUT and GND pins.
Does AP7366EA-12W5-7 require a minimum load current?
No - the AP7366EA-12W5-7 remains stable and regulated at zero load. This is confirmed in the datasheet's "No Load Stability" section and enables use in standby/sleep modes where downstream circuitry draws negligible current, eliminating need for bleed resistors.
How does the EN pin behave when left floating?
The EN pin has an internal 3MΩ pull-down resistor, so it defaults to logic low (disabled state) when left floating. To ensure reliable turn-on, connect EN directly to VIN or a controlled logic signal; do not rely on weak pull-ups from other ICs, as VIH threshold is 1.0V minimum and input leakage is ±0.1μA.
