The LD6806F/28H is a low dropout (LDO) linear voltage regulator manufactured by NXP. It's designed to provide a stable and regulated output voltage from a higher input voltage, even when the input voltage is close to the desired output voltage. This makes it suitable for a variety of applications where a clean and stable power supply is needed.

Applications

• Portable devices: Mobile phones, tablets, and other battery-powered devices.
• Wireless communication devices: Wi-Fi modules, Bluetooth devices, and other RF circuits.
• Microcontroller power supplies: Providing stable power to microcontrollers in embedded systems.
• Consumer electronics: DVD players, set-top boxes, and audio equipment.

Features

• Low dropout voltage: Operates with a small difference between input and output voltage.
• Fixed output voltage: Provides a stable and precise 2.8V output.
• Low quiescent current: Minimizes power consumption in standby mode.
• Short-circuit protection: Protects the regulator and the load from damage.
• Thermal shutdown protection: Prevents overheating and damage to the regulator.
• Small package: Available in compact surface-mount packages.

Benefits

• Extended battery life: Low quiescent current helps conserve battery power in portable devices.
• Stable output voltage: Provides a clean and reliable power supply for sensitive circuits.
• Protection against faults: Short-circuit and thermal shutdown protection enhance reliability.
• Easy to use: Requires minimal external components.
• Compact design: Small package allows for integration in space-constrained applications.

Technical Specifications: The LD6806F/28H typically has an input voltage range of 2.5V to 5.5V and provides a fixed output voltage of 2.8V with a specified output current. It features a low dropout voltage, typically less than 200mV at the rated output current. It incorporates short-circuit protection and thermal shutdown features. The quiescent current is very low, typically in the microampere range. Package options usually include small surface-mount packages like SOT-23 or similar.
