STMicroelectronics LDK320 High PSRR Voltage Regulator

STMicroelectronics LDK320 High PSRR Voltage Regulator provides a maximum output current of 200mA from an input voltage in the range of 2.5V to 18V. The LDK320 has a typical dropout voltage of 100mV and is stabilized with a ceramic capacitor on the output. The regulator is suitable for low power battery-powered applications. An enable logic control function allows for a shutdown mode that consumes a total current lower than 1μA. This device also includes short-circuit current limiting, thermal and SOA protections.

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.

LDK320 High PSRR Voltage Regulators

STMicroelectronics LDK320 High PSRR Voltage Regulators are low drop voltage regulators with a maximum 200mA output current from a 2.5V to 18V input voltage range. The regulators have a typical dropout voltage of 100mV and are stabilized with a ceramic capacitor on the output. The LDK320 are ideal for low battery powered applications with a very good dynamic characteristic, combined with low drop voltage and low quiescent current. The enable logic control function allows the LDK320 to be in shutdown mode by consuming a total current lower than 1μA. This device also includes a short-circuit current limiting, thermal, and SOA protections.
