Linear Regulators & Controllers

Semtechs low dropout (LDO) product portfolio offers a broad range of high performing and feature-rich solutions. Our dropout linear regulator families include Single, Dual and Multiple LDO linear regulators, as well as General Purpose, Ultra-low Dropout, and Low-Noise. Our LDO voltage controller products consist of both single and multiple linear controllers.

Our low dropout regulator and low dropout controller ICs can operate with input voltages ranging from a very low 1.4V to up to 16V. These devices are complemented by a very low dropout voltage and offer output currents from 100mA to 3A with fast transient response and excellent line and load regulation. Our low dropout LDO products are used in a variety of applications, from desktop motherboards and graphics cards to almost any battery powered system such as notebook PCs, cell phones, PDAs, handsets and more.
