Linear & Switching Voltage Regulators

LP3856ES-2.5/NOPB Description

The LP3856ES-2.5/NOPB is a high-performance, fixed-output linear voltage regulator from Texas Instruments, designed to deliver a stable 2.5V output at up to 3A of continuous current. With a wide input voltage range of up to 7V, this regulator is optimized for low dropout operation, featuring a maximum dropout voltage of 0.6V at 3A, ensuring efficient power conversion even under high load conditions. The device is housed in a DDPAK/TO-263-5 surface-mount package, making it suitable for space-constrained applications. Its 73dB to 57dB PSRR (120Hz) ensures excellent noise rejection, critical for sensitive analog and digital circuits.

LP3856ES-2.5/NOPB Features

• High Current Output: Supports up to 3A with low dropout (0.6V @ 3A), ideal for powering high-load systems.
• Low Quiescent Current: 4 mA typical, enhancing efficiency in battery-operated applications.
• Robust Protection: Integrated over-current, over-temperature, and short-circuit protection safeguards the regulator and downstream components.
• Enable Control: Features an enable pin for power management, allowing dynamic shutdown to reduce power consumption.
• High PSRR: 73dB at 120Hz minimizes output ripple, making it suitable for noise-sensitive applications.
• Wide Operating Range: Input voltage up to 7V accommodates various power sources.
