Ultra-Low Noise Linear Regulator

Ultra-Low Noise Linear Regulator

STMicroelectronics has launched an ultra-low noise linear regulator IC that provides 1A of current from a 1.8V to 5.5V input voltage range with a typical dropout voltage of 120mV. The LD56100 is housed in a DFN8 (1.2mm x 1.6mm) package, allowing considerable space savings. The device is stabilized with a ceramic capacitor on the output.

The regulator is suitable for low power battery operated applications with features like an ultra-low drop voltage, low quiescent current, fast transient response and internal soft start circuit.
