CS8361YDPSR7G

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

The CS8361YDPSR7G is a dual-output linear voltage regulator from onsemi, housed in a D2PAK-7 package. It provides a fixed 5.0 V standby output capable of delivering 100 mA with ±2% accuracy and a typical dropout voltage of 400 mV. The second output tracks the standby rail via an external adjust lead, supporting up to 250 mA with a similar 400 mV dropout at rated current. The device includes an active-low ENABLE control for the tracking output and a RESET function that monitors the 5.0 V standby rail, ensuring system reliability during power-up or dropout conditions.
