The S-812C30BPI-C4KTFG is an integrated power supply LDO (low dropout voltage regulator) which is optimized for mobile device power management, providing efficient and reliable voltage regulation in a small package. It is designed to provide fast transient response, improved thermal performance and low noise output.

Overview

The S-812C30BPI-C4KTFG is a linear voltage regulator with an operating temperature range of -40°C to +85°C. It features an adjustable output voltage range between 1.8 V and 5.5 V, and a maximum output current of up to 1.5 A. The S-812C30BPI-C4KTFG is a fast, easy-to-use solution with a convenient, built-in over-current protection (OCP) and a reverse-power protection capability. It has low drop-out (LDO) operation, a current-limited linear regulation that operates at low quiescent current, and a low output noise level.

The S-812C30BPI-C4KTFG features an onboard power supply supervisor (PSS) to detect, monitor, and protect against over-voltage, over-temperature, and over-current conditions. The output current of the voltage regulator can be accurately controlled up to 1.5A with a 0.2A accuracy by using external resistors, resulting in improved energy efficiency and longer battery life for mobile devices.
