Diodes Incorporated AP1117D15LA Voltage Regulator

The AP1117D15LA from Diodes Incorporated is a robust low dropout voltage regulator designed to deliver a fixed output of 1.5V with an output accuracy within ±1%. This component is part of the AP1117 series, known for its high efficiency and reliability in a variety of applications, including consumer electronics, industrial hardware, and embedded systems.

Capable of handling an input voltage range from 2.85V to 18V, the AP1117D15LA can deliver an output current of up to 1A, making it suitable for moderate power requirements. Its low dropout voltage, typically 1.3V at full load, ensures efficient operation close to the input voltage level, minimizing power loss and heat generation.

The AP1117D15LA comes in a TO-252 (DPAK) package, which is widely used in surface-mount technology and is known for its compact footprint and excellent thermal performance. This package allows for efficient heat dissipation, which is critical for maintaining stability and prolonging the life of the regulator under various load conditions.

Featuring built-in current limiting and thermal shutdown protection, the AP1117D15LA safeguards against overcurrent and overheating scenarios, enhancing the safety and reliability of the end application. Additionally, the device offers a low quiescent current, which is beneficial for battery-powered devices where power conservation is crucial.

For design flexibility, the AP1117D15LA only requires minimal external components, typically a pair of capacitors for input and output stabilization. This simplicity aids in creating a clean and efficient power supply design with reduced bill of materials and board space requirements.

In summary, the AP1117D15LA from Diodes Incorporated is a high-quality, fixed-output voltage regulator that provides a stable 1.5V supply with excellent load and line regulation characteristics. Its thermal and current protection features, along with its low dropout performance, make it an ideal choice for a wide range of power management applications.
