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.
