Low Dropout (LDO) Regulators

STMicroelectronics Low Dropout (LDO) Linear Regulators are a cost-effective way to deliver a stable and regulated output voltage. The LDOs simplify designs with few external components. Low-dropout linear regulators (LDOs) 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.

LDK220 Low Drop Voltage Regulators

STMicroelectronics LDK220 Low Drop Voltage Regulators provide a maximum output current of 200mA  from an input supply voltage in the range of 2.5V to 13.2V with a typical dropout voltage of 100mV. It is stabilized with a ceramic capacitor on the output. An enable logic control function puts the LDK220 in shutdown mode allowing a total current consumption lower than 1μA. The device also includes a short-circuit constant current limiting and thermal protection. LDK220's very low drop voltage, low quiescent current, and low noise make it well-suited for battery-powered applications.
