The AP2181A and AP2191A are integrated high-side power switches optimized for Universal Serial Bus (USB) and other hot-swap applications. This family of devices complies with USB 2.0 and is available with both polarities of Enable input. The AP2181A and AP2191A offer current and thermal limiting and short circuit protection as well as controlled rise time and undervoltage lockout functionality. A 7ms deglitch capability on the open-drain Flag output prevents false over-current reporting and does not require any external components.

The AP2317 is a series of low dropout three-terminal regulators with a dropout of 1.1V at 600mA output current. This product has been optimized for low voltage where transient response and minimum input voltage are critical. The AP2317 provides current limit and thermal shutdown. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within ±1%. On-chip thermal shutdown provides protection against any combination of overload and ambient temperatures that would create excessive junction temperatures. The AP2317 is available in 2.5V and 3.3V versions. The fixed versions integrate the corresponding resistor divider. It is also available in an adjustable version which can set the output voltage with two external resistors.
