Introducing the LP38851T-ADJ from Texas Instruments

The LP38851T-ADJ is a high-performance, low-dropout linear regulator (LDO) that offers outstanding ac performance with very low ground current. Manufactured by Texas Instruments, a leader in semiconductor solutions, this regulator is designed to provide precision, low-noise output with a high power supply rejection ratio (PSRR) and low quiescent current, making it an ideal choice for high-end electronics where stable and reliable power is critical.

Key Features

• Adjustable Output: The LP38851T-ADJ provides an adjustable output voltage that can be set with external resistors from 1.2V to 5V, allowing for flexible use across various applications.
• High Current Capability: This LDO can deliver up to 800mA of continuous output current, making it suitable for powering a wide range of ICs and devices.
• Low Dropout Voltage: The device features a low dropout voltage, typically 75mV at a 800mA load, which helps in maintaining regulation even when the supply voltage is close to the output voltage.
• Excellent Load and Line Transient Response: With its fast transient response, the LP38851T-ADJ can handle rapid changes in load and line conditions without compromising the stability of the output voltage.
• Thermal Protection: The regulator includes built-in thermal shutdown protection that safeguards the device and the system during conditions of excessive power dissipation.
