Low Dropout (LDO) Regulators

STMicroelectronics Low Dropout (LDO) Linear Regulators deliver a stable and regulated output voltage. The LDOs simplify designs with few external components. Low dropout linear regulators provide the best cost-performance tradeoff.

Ultralow Dropout LDOs

STMicroelectronics Ultra Low Dropout LDOs are a wide range of low and medium-power LDO regulators with ultralow dropout and fast transient response. These ultralow LDOs simplify the design of high-efficiency, cost-effective linear power management (from 50mA to 3A of continuous load current). This makes them ideal for DSPs, MCUs, and FPGAs.
