Additional benefits of the device include a high 75dB power supply rejection ratio (PSRR) and low 60μVrms noise sensitivity (from 10Hz to 100kHz). These are key to getting the best performance from audio and video applications or communications devices with RF sub-systems, such as wireless adaptors. A wide input voltage specification ensures compatibility with lithium batteries down to 1.7V, while the output voltage, which can be fixed between 1.2 and 3.6V, is maintained to 1% accuracy at +25oC and 1.5% across the full -40 to +85ºC operating temperature.
The AP7342 is available in single-reel, 5,000-piece quantities and priced at $0.25 each.
