LDL1117S30R General Description

One of the standout features of the LDL1117S30R is its impressive power supply rejection ratio of 87 dB at 120 Hz, tapering off to more than 40 dB at 100 kHz. This makes it well-suited for use in switch-mode power supplies (SMPS) and as a secondary regulator in DC-DC converters. Additionally, the device includes built-in protections such as current limiting, Safe Operating Area (SOA) protection, and thermal shutdown to ensure reliable operation and prevent damage in case of faults

Key Features

Efficient regulator
Small size
800mA output
