AP2218 - BCD Semiconductor

AP2218 LOW DROPOUT LINEAR REGULATOR

The AP2218 is a low dropout linear regulator with a typical dropout of 300mV at 1A output current. The AP2218 provides current limit and thermal shutdown. On-chip thermal shutdown provides protection against any combination of high current and ambient temperature that would create excessive junction temperatures. The AP2218 has 3.3V and 5.0V versions. The AP.
