CS8361YDPSR7G

CS8361YDPSR7G Description

The CS8361YDPSR7G from onsemi is a dual-output, fixed linear voltage regulator designed for precision power management in demanding applications. This obsolete but reliable IC delivers 5V and a tracking output with a 100mA/250mA current capacity per channel, making it suitable for low-power systems requiring stable voltage rails. Its 26V maximum input voltage and low dropout (0.6V @ 100mA, 0.7V @ 250mA) ensure efficient operation even with fluctuating input sources. Packaged in a D2PAK (TO-263) surface-mount format and supplied in Tape & Reel (TR), it is optimized for automated assembly.

CS8361YDPSR7G Features

• Dual Positive Outputs: Fixed 5V and tracking output for flexible voltage rail configurations.
• High PSRR (70dB @ 120Hz): Excellent noise rejection for sensitive analog/digital circuits.
• Low Quiescent Current (200µA): Enhances efficiency in battery-operated devices.
• Robust Protection: Integrated safeguards against over-temperature, over-voltage, reverse polarity, and short circuits.
• Control Features: Enable/Reset pins for power sequencing and system management.
• Wide Input Range (Up to 26V): Accommodates varying supply voltages in automotive/industrial environments.
• RoHS3 & REACH Compliant: Meets environmental and regulatory standards.
