CS8182YDFR8

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

The CS8182YDFR8G is a monolithic low dropout tracking regulator from onsemi, housed in an SO-8 package. It provides an adjustable buffered output voltage that closely tracks the reference input with a worst-case error of ±10 mV. The device delivers up to 200 mA of source current and operates within a wide input voltage range of 3.4 V to 45 V. Key electrical characteristics include a typical dropout voltage of 350 mV at 200 mA and a quiescent current of 75 µA during operation. It features thermal shutdown, short circuit protection, and reverse battery protection, making it suitable for automotive environments.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix 'YDFR8G' against the manufacturer's current datasheet to confirm availability status. The documentation indicates that certain variants within the CS8182 family may be discontinued or not recommended for new designs. Ensure the component meets all required automotive qualification standards before integration into final products.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a linear regulator must precisely mirror a reference voltage rather than providing a fixed output. Consider the SO-8 package thermal resistance and copper area requirements for heat dissipation. Verify that the application load current does not exceed the 200 mA limit and that the input voltage remains within the specified operational range.
