CS8161YTVA5

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

The CS8161YTVA5 is a dual-output linear regulator in a TO-220 vertical package. It provides a primary 12 V output capable of sourcing 400 mA and a secondary 5.0 V output sourcing 200 mA. The device features an ENABLE pin that controls both outputs, entering sleep mode with 200 nA quiescent current when low. It supports input voltages from -15 V to 26 V and includes reverse battery protection up to -15 V DC, 74 V load dump tolerance, and thermal shutdown.

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

• Dual regulated outputs for simultaneous power supply requirements
• Integrated enable function for synchronized control and ultra-low sleep mode current drain
• Comprehensive fault protection including reverse polarity, load dump, short circuit, and thermal shutdown

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

• Automotive radio systems requiring synchronized display and tuner power
• Microprocessor-controlled circuits requiring energy-saving sleep modes
• General purpose dual voltage regulation in industrial equipment

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

Verify the specific suffix (TVA) matches the required lead configuration for your PCB footprint. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Ensure adequate heatsinking is planned as the TO-220 package relies on thermal resistance calculations for high-power dissipation scenarios.

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

Select this component when a single IC must provide two distinct regulated voltages with shared enable logic. It is suitable for applications where space efficiency is prioritized over discrete solutions. Verify that the maximum junction temperature and thermal resistance constraints are met within the intended operating environment.

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

This part belongs to the CS8161 family of dual regulators manufactured by onsemi. It utilizes a five-lead TO-220 package designed for through-hole mounting. The device integrates bandgap references and pre-regulators to maintain stability across varying input conditions and temperatures.

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

Direct substitutes include other CS8161 variants such as CS8161YT5 or CS8161YTHA5, which share identical electrical characteristics but differ in lead orientation. Cross-brand replacements require matching dual-output topology, current ratings, and package dimensions.
