L7815CP

L7815CP Description

The L7815CP from STMicroelectronics is a fixed-output positive linear voltage regulator designed to deliver a stable 15V output at up to 1.5A of continuous current. Housed in a TO-220FP package, this through-hole-mount IC is engineered for robustness, featuring over-temperature and short-circuit protection to ensure reliable operation in demanding environments. With an input voltage range up to 35V and a low dropout voltage of 2V (typical at 1A), the L7815CP is optimized for applications requiring precise voltage regulation. Its 54dB PSRR (120Hz) ensures excellent noise rejection, making it suitable for sensitive analog and digital circuits.
