CS8156YTVA5G

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

The CS8156YTVA5G is a low dropout dual output linear regulator manufactured by onsemi. It provides two regulated outputs: VOUT1 at 12 V with a maximum current of 750 mA, and VOUT2 at 5.0 V with a maximum current of 100 mA. The device features an onboard ENABLE function that switches the regulator into SLEEP mode when pulled low, reducing quiescent current to 200 nA. It operates within an input voltage range of -0.5 to 26 V and withstands peak transient voltages up to +60 V and -50 V. The component is housed in a TO-220 five-lead vertical package (CASE 314K) suitable for through-hole mounting.

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

Verify the specific suffix 'YTVA5' corresponds to the TO-220 Five Lead Vertical package (CASE 314K). Confirm RoHS compliance status as indicated by the 'G' suffix if applicable to your supply chain requirements. Check datasheet revision history for any updates to electrical characteristics or thermal data before finalizing design specifications.

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

Select this component when a single solution is required to generate both 12 V and 5 V rails from a higher input voltage. Ensure the application can accommodate the thermal dissipation associated with the TO-220 package, potentially requiring a heatsink for high load currents. Verify that the ENABLE signal logic levels are compatible with the CMOS input threshold for proper switching between active and sleep states.
