S-19218B80A-V5T2U7

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

The S-19218B80A-V5T2U7 is an automotive-grade linear voltage regulator from the ABLIC S-19218 series. It provides a fixed 8.0 V output with ±1.5% accuracy across a junction temperature range of -40°C to +125°C. The device supports up to 500 mA output current and operates with an input voltage range of 3.0 V to 36.0 V. Key electrical parameters include a typical dropout voltage of 0.17 V at 200 mA, line regulation of 0.025 %/V, and ripple rejection of 50 dB. It features built-in overcurrent protection, thermal shutdown at 170°C, and an ON/OFF control pin.

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

• Built-in overcurrent protection circuit limits output current during short-circuit or overload conditions.
• Thermal shutdown circuit stops regulation when junction temperature reaches 170°C to prevent damage.
• ON/OFF pin controls internal operation and includes discharge shunt function for rapid output capacitor discharge.

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

• Constant-voltage power supply for vehicle interior electrical applications
• Power supply for engine, transmission, suspension, and ABS systems
• Related devices for EV, HEV, and PHEV applications

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

Verify the specific ordering suffix V5T2U7 corresponds to the TO-252-5S(A) package and tape reel packing configuration as defined in the official product name structure. Confirm that the B designation indicates positive logic for the ON/OFF pin functionality before finalizing procurement specifications.

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

Select this component for designs requiring high withstand voltage up to 36 V and fast transient response. Ensure the application utilizes ceramic capacitors meeting the minimum capacitance requirements for stability. Evaluate thermal dissipation constraints carefully, as large load currents may trigger thermal shutdown if power dissipation limits are exceeded.
