CS8151YDPSR7G

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

The CS8151YDPSR7G is a fixed-output linear voltage regulator manufactured by onsemi. It provides a stable 5V output with a maximum current capacity of 100mA. The device operates within an input voltage range up to 26V and features a typical dropout voltage of 0.6V at full load. It incorporates comprehensive protection mechanisms including over-temperature, over-voltage, and short-circuit limiting. Additional control features include reset, wake-up, and watchdog functions. The component is housed in a D2PAK-7 surface-mount package and supports operation across a wide temperature range from -40°C to 125°C.
