The AP1184K5-18L-U is a high-performance low dropout linear regulator (LDO) from Diodes Incorporated, designed to deliver a continuous output current of up to 5A with a minimal dropout voltage. This makes it an ideal solution for powering core voltages of microprocessors as well as for post-regulation applications.

Key Features

• Output Voltage: This LDO provides a fixed output voltage of 1.8V, suitable for a variety of low-voltage applications.
• High Output Current: Capable of delivering up to 5A of continuous output current, it meets the needs of high-power systems.
• Low Dropout: The low dropout feature ensures efficient operation even when the input voltage is very close to the output voltage, enhancing system efficiency.
• Stable with Low ESR Output Capacitor: The AP1184K5-18L-U remains stable with ceramic capacitors, which have lower equivalent series resistance (ESR) than tantalum or aluminum electrolytic capacitors, leading to improved transient response and reduced noise.
• Over-Temperature and Over-Current Protection: Built-in protection mechanisms safeguard the device and the system against conditions that may lead to damage.
• Adjustable Current Limit: The current limit can be set via an external resistor, allowing for customization based on specific application requirements.
• Thermal Shutdown: An internal thermal shutdown feature prevents the regulator from overheating, thus ensuring reliable operation over a range of temperature conditions.
