CS8182YDF8

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

The CS8182YDF8 is a monolithic low dropout tracking regulator 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. It features thermal shutdown, short circuit protection, and reverse battery protection. The VREF/ENABLE pin controls operation and sleep mode.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Output voltage closely tracks the reference input signal
• Integrated thermal shutdown and short circuit protection
• Capable of withstanding automotive load dump transients
• Low quiescent current consumption in active and sleep modes

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

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

Verify the specific suffix against the manufacturer's ordering information table. The CS8182YDF8G is listed as discontinued for new designs. Confirm availability status and lead times directly with authorized distributors or onsemi representatives before procurement planning.

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

Select this component when precise voltage tracking relative to a reference signal is required rather than a fixed output. Ensure the application load does not exceed the 200 mA continuous current limit. Verify that the input voltage remains within the recommended operating range of 3.4 V to 45 V under all transient conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the CS8182 family of linear voltage regulators designed for micropower applications. It is distinct from fixed-output LDOs by its ability to track an external reference voltage. The SO-8 package variant offers internally fused leads for enhanced reliability in harsh environments.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

The datasheet lists CS8182YDFR8G as a discontinued alternative. No other direct substitute part numbers are explicitly confirmed in the provided documentation. Consult onsemi sales for current recommendations if the discontinued status affects supply chain continuity.
