AP7369Q-50E-13 High-Voltage LDO Voltage Regulator

The AP7369Q-50E-13 from Diodes Incorporated is a precision automotive-grade low dropout (LDO) voltage regulator designed for high-reliability applications requiring stable 5V output. This advanced linear regulator combines exceptional performance with robust protection features, making it ideal for automotive electronics, industrial control systems, and battery-powered devices.

Key Features & Benefits

• Wide Input Voltage Range: Operates from up to 45V input, providing flexibility for various power supply configurations
• Ultra-Low Quiescent Current: Only 8µA standby current maximizes battery life in portable applications
• Excellent PSRR Performance: 85dB at 1kHz ensures clean output voltage even with noisy input supplies
• Automotive-Grade Reliability: AEC-Q101 qualified for demanding automotive environments (-40°C to 125°C)
• Comprehensive Protection: Built-in overcurrent, over-temperature, and short-circuit protection safeguards your system
• Compact SOT-223-3 Package: Space-saving surface mount design for high-density PCB layouts

Applications

The AP7369Q-50E-13 is perfectly suited for:

• Automotive infotainment and dashboard systems
• Industrial sensor and control circuits
• Battery-powered IoT devices
• Microcontroller and FPGA power supplies
• Portable medical equipment
• Wireless communication modules

Performance Advantages

This LDO voltage regulator stands out with its exceptional combination of low quiescent current and high input voltage capability. The 8µA standby current makes it ideal for always-on applications where battery life is critical, while the 45V input range provides robust protection against voltage transients common in automotive and industrial environments.

The excellent power supply rejection ratio (PSRR) of 85dB at 1kHz ensures your sensitive analog circuits receive clean, stable power even when the input supply is noisy. This is particularly important in automotive applications where alternator noise and load dump transients can affect system performance.

Design Considerations

When implementing the AP7369Q-50E-13 in your design, consider the following best practices:

• Input Capacitor: Use a minimum 1µF ceramic capacitor close to the input pin for stability
• Output Capacitor: A 2.2µF or larger ceramic capacitor is recommended for optimal transient response
• Thermal Management: The SOT-223 package provides good thermal performance, but ensure adequate PCB copper area for heat dissipation in high-current applications
• Layout: Keep input and output capacitors as close as possible to the regulator pins to minimize parasitic inductance
