High PSRR Voltage Regulators

High PSRR Voltage Regulators

STMicroelectronics has released low dropout (LDO) voltage regulators with a maximum 200mA output current from a 2.5V to 18V input voltage range. The LDK320 high power supply rejection ratio (PSRR) regulators each have a dropout voltage of 100mV (typical) and are stabilized with a ceramic capacitor on the output.

The regulators are suitable for battery powered applications. The enable logic control function allows these devices to be placed into shutdown mode – consuming a total current lower than 1μA.
