AP7343D-33FS4-7B

AP7343D-33FS4-7B is a AP7343 series low dropout regulator with 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 AP7343 includes a voltage reference, error amplifier, current limit circuit, and an enable input to turn it on and off. With the integrated resistor network fixed output voltage versions can be delivered. With its low power consumption and line and load transient response, the AP7343 is well suited for low-power handheld communication equipment. Typical applications include smart phone/PAD, RF supply, cameras, portable videos, portable media players, wireless adapters and wireless communication.
