Product details

3.0 V fixed LDO with 100 mA and 0.6 V dropout

The LP2950CDTX-3.0: Its maximum dropout voltage of 0.6 V at full load keeps the headroom requirement low — useful when regulating from a 3.6 V lithium cell or a 5 V rail that sags under load. Input voltage tolerance extends to 30 V maximum. Quiescent current is 120 µA typical.

Built-in protection for industrial and automotive environments

The LP2950CDTX-3.0 integrates over-current, over-temperature, and short-circuit protection, reducing the need for external supervisory components.

Package and mounting: TO-252-3 (DPak)

The supplier device package is TO-252-3; the listed package form is Tape & Reel (TR).
