Product details
Overview
AP7366EA-15SN-7 from Diodes Incorporated is a 600mA fixed-output low-dropout linear regulator with 1.5V output, 60μA quiescent current, 300mV dropout at full load, and integrated enable control. It operates from 2.2V to 6V input and delivers stable regulation for FPGA I/O rails, portable device core supplies, and battery-powered sensor nodes requiring low-noise, fast transient response.
For engineers reviewing the AP7366EA-15SN-7 datasheet, AP7366EA-15SN-7 pinout, AP7366EA-15SN-7 application, or AP7366EA-15SN-7 equivalent, key selection criteria include dropout voltage at 600mA, thermal resistance of U-DFN2020-6 package (46.2°C/W), PSRR at 1kHz (75dB), start-up time (150μs), and EN logic thresholds (VIH = 1.0V, VIL = 0.3V).
Technical Context
The AP7366EA-15SN-7 implements a PMOS pass transistor architecture with internal 0.8V bandgap reference and error amplifier, enabling precise 1.5V output regulation across -40°C to +85°C ambient. Its current-limit and thermal-shutdown circuitry activate at 1.0A and +150°C respectively, with 20°C hysteresis.
Designed for ceramic-capacitor stability, it requires only 1μF output capacitance and achieves excellent line/load transient response due to fast gate drive and low output impedance. The U-DFN2020-6 package provides 46.2°C/W θJA, supporting up to ~450mW dissipation in still air before thermal limiting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5V ±1.5% accuracy at 10mA load ensures reliable biasing of 1.5V I/O standards. |
| Max Output Current | 600mA continuous delivery supports mid-power digital loads like FPGA I/O banks or MCU peripherals. |
| 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 from 1.8V input, critical for single-cell Li-ion or LiFePO₄ systems. |
| PSRR | 75dB at 1kHz suppresses switching noise from adjacent DC/DC converters feeding the LDO input. |
| Start-up Time | 150μs enables rapid power sequencing in multi-rail systems without external timing components. |
| Thermal Shutdown | +150°C trip with +20°C hysteresis prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
AP7366EA-15SN-7 is packaged in a 2.0mm × 2.0mm U-DFN2020-6 with wettable flank leads and exposed thermal pad. The package supports high-density layouts and efficient heat transfer to PCB copper planes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 3) | Input voltage supply | Accepts 2.2–6V; requires ≥1μF MLCC bypass to GND within 2mm for EMI suppression and stability. |
| GND (Pin 2) | Power ground reference | Low-impedance return path; must connect directly to thermal pad and system ground plane. |
| EN (Pin 1) | Enable control input | Active-high logic interface; VIH ≥1.0V ensures compatibility with 1.8V/3.3V GPIO; internal 3MΩ pull-down aids default-off behavior. |
| OUT (Pin 4) | Regulated output | Delivers 1.5V ±1.5%; requires ≥1μF ceramic capacitor placed adjacent to pin for transient response and stability. |
| ADJ (Pin 6) | Feedback reference node | Internally tied to 0.8V reference; left unconnected in fixed-output variants-no external resistor network required. |
| NC (Pin 5) | No internal connection | Floating or grounded per layout convenience; no electrical impact on regulation or protection functions. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 60μA quiescent current minimizes standby power loss in battery-backed real-time clocks and IoT edge sensors. |
| Fast transient response | Load step recovery within 200μs (50mA→500mA) maintains <20mV output deviation, protecting sensitive analog circuitry. |
| Single-ceramic-capacitor stability | Stable with 1μF X5R/X7R MLCC output capacitor eliminates need for bulk electrolytics, reducing BOM count and board area. |
| Integrated protection | Current limit (~1.0A), 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, single-cell Li-ion, or buck converter outputs 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 |
|---|---|---|---|
| MCP1703T-1502E/MB | Higher IQ (1.6μA vs. 60μA), lower max current (250mA), SOT-23-5 package (θJA = 210°C/W) | Better for micropower (<100μA) but unsuitable for >300mA loads or thermally constrained layouts | Select if ultra-low standby dominates over peak current capability and thermal performance. |
| Torex XC6219B152MR-G | Lower IQ (1.0μA), same 1.5V output, but only 300mA rated and no EN pin; SOT-25 package | Lacks enable control and thermal shutdown; limited to low-current, always-on applications | Choose only when enable functionality and robust fault protection are not required. |
Compared with MCP1703T-1502E/MB and XC6219B152MR-G, AP7366EA-15SN-7 uniquely balances 600mA delivery, 60μA IQ, integrated EN, and thermal protection in a thermally efficient 2×2mm package-making it optimal for space-constrained, medium-power embedded systems demanding both efficiency and reliability.

FAQ
What is the minimum input voltage required for AP7366EA-15SN-7 to maintain 1.5V regulation at 600mA?
The minimum input voltage is 1.8V, calculated as VOUT + VDROPOUT = 1.5V + 0.3V. At 600mA load and +25°C, the dropout is guaranteed ≤300mV per datasheet Table 1. Below 1.8V input, output voltage drops proportionally and regulation is lost.
Can AP7366EA-15SN-7 operate without an external output capacitor?
No. A minimum 1μF ceramic capacitor is mandatory between OUT and GND for stability and transient response. Omitting it causes oscillation and potential damage. The device is optimized for low-ESR MLCCs; tantalum or aluminum electrolytics require careful ESR matching and are not recommended.
Is the EN pin internally pulled up or down, and what happens if left floating?
The EN pin has an internal 3MΩ pull-down resistor (per datasheet Electrical Characteristics). If left floating, the device remains disabled. To ensure reliable turn-on, tie EN directly to IN or use a GPIO with VIH ≥1.0V; avoid open-drain drivers without pull-up.
Does AP7366EA-15SN-7 require a minimum load current to maintain regulation?
No. The device is stable and fully regulated at zero load current, as confirmed in the Application Information section. No minimum load is needed-ideal for intermittent-sensing applications where the downstream circuit draws current only during brief active periods.
