The APL5312-18S5I-TRL is a dual, low dropout (LDO) linear regulator manufactured by Anpec Electronics. It provides two independent regulated output voltages, making it suitable for applications requiring multiple voltage rails. It is designed for efficiency and compact size, ideal for portable and battery-powered devices.

Applications

• Portable Electronics: Powering multiple components with different voltage requirements.
• Smartphones and Tablets: Supplying power to various ICs within the device.
• Wireless Modules: Regulating voltage for RF transceivers and other wireless components.
• Digital Cameras: Providing stable power for image sensors and processors.
• Wearable Devices: Efficiently managing power in compact wearable applications.

Features

• Dual LDO Regulators: Provides two independent regulated output voltages.
• Low Dropout Voltage: Maintains regulation with minimal input-output voltage difference.
• Low Quiescent Current: Minimizes power consumption in standby mode.
• Independent Enable Control: Allows each regulator to be enabled or disabled separately.
• Over-Current Protection: Protects the regulator and the load from excessive current.

Benefits

• Reduced Component Count: Integrates two regulators into a single package, saving board space.
• Extended Battery Life: Low quiescent current and efficient regulation prolong battery life.
• Improved System Flexibility: Independent enable control allows for flexible power management.
• Enhanced Reliability: Over-current protection prevents damage and ensures stable operation.
• Simplified Design: Easier to implement multiple voltage rails compared to using multiple single-output regulators.

Additional Details

The APL5312-18S5I-TRL typically provides output voltages of 1.8V and 0.5V, but specific voltages can vary. It comes in a small surface-mount package. The low dropout voltage ensures stable regulation even when the input voltage is close to the output voltage. The independent enable control allows designers to selectively power down portions of the circuit to conserve power. Detailed electrical characteristics, including input voltage range, output current capability, dropout voltage, and thermal resistance, are available in the product datasheet.
