Product details

Fixed 15 V rail, 400 mA — what it delivers

Built-in protection covers over-temperature, reverse polarity, and short-circuit conditions — reducing the need for external clamp diodes or crowbar circuits on the output rail.

Dropout and quiescent — the real-world margins

Maximum dropout is 1 V at 50 mA load; at full 400 mA the dropout will be higher. Maximum input voltage is 26 V, giving headroom for unregulated supplies. The fixed output eliminates the feedback divider.

This part is officially listed as Obsolete. No successor or cross-reference is recorded in the available lifecycle data.
