LT1528CQ#PBF

LT1528CQ#PBF Description

The LT1528CQ#PBF from Analog Devices Inc. is a high-performance, 3A low-dropout (LDO) linear voltage regulator designed for demanding power management applications. It supports an adjustable output voltage (3.3V to 14V) or a fixed 3.3V option, with a wide input voltage range up to 15V. The device features a low dropout voltage of 0.85V at 3A, ensuring efficient operation even with minimal headroom. Packaged in a 5-lead DDPAK (TO-263) surface-mount form factor, it is optimized for space-constrained designs while delivering robust thermal performance.
