CS8161YTHA5

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

The CS8161YTHA5 is a dual-output linear regulator providing 12 V at 400 mA and 5.0 V at 200 mA. It features an ENABLE pin for sleep mode control, drawing 200 nA when inactive. The device supports input voltages from -15 V to 26 V, with overvoltage protection up to 74 V. Electrical characteristics include line regulation of 80 mV for the primary output and 50 mV for the secondary. Thermal shutdown activates at 150 °C typical. The component utilizes a five-lead TO-220 horizontal package (CASE 314A) with a copper tab for thermal management.

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

Verify the specific suffix 'YTHA5' corresponds to the horizontal lead configuration within the TO-220 five-lead package family. Confirm RoHS compliance status if environmental regulations apply, as indicated by the 'G' suffix variant. Ensure input voltage ranges align with system battery specifications, particularly regarding reverse polarity and load dump tolerances. Validate thermal requirements against the junction-to-ambient resistance data for the selected mounting orientation.

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

Select this component when simultaneous 12 V and 5.0 V regulation is required from a single supply rail. The integrated enable function simplifies control logic compared to separate regulators. Consider the thermal dissipation capabilities of the TO-220 package for high-load applications. Verify that the dropout voltage characteristics meet the minimum input voltage constraints of the target application across the full operating temperature range.
