The AP7368 is a low dropout regulator featuring 500mA/1A that provides high output voltage accuracy, low RDS(on), high PSRR, low output noise, and low quiescent current. This regulator is based on a CMOS process.
The AP7368 includes a voltage reference, error amplifier, current-limit circuit, and enable inputs to turn on and off separately. With the integrated resistor network, fixed output voltage versions can be delivered.
With the device’s low power consumption and line and load transient response, the AP7368 is well suited for low power handheld communication equipment. The AP7368 can select the output current limit 1.0A or 500mA by alternating the LCON pin between “H” or “L”. The AP7368 is packaged in the X1-DFN1612-8 (Type B) package, allowing for the smallest footprint and a dense PCB layout.
