CS8151YT7G

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The CS8151YT7G is a positive fixed linear voltage regulator manufactured by onsemi, designed for applications requiring stable power delivery. It provides a fixed output voltage of 5V with a maximum output current capability of 100mA. The device features a low dropout voltage of 0.6V at full load and offers high power supply rejection ratio (PSRR) of 75dB at 120Hz. It integrates comprehensive protection mechanisms including over-temperature shutdown, over-voltage protection, and short-circuit limiting. The component is housed in a TO-220-7 through-hole package and operates within an extended temperature range of -40°C to +125°C.
