Diodes Incorporated AP7353 Low Noise Low Dropout Regulators

Diodes Incorporated AP7353 Low Noise Low Dropout Regulators are ideal for handheld/wearable communication equipment that require stable voltage sources. Diodes Incorporated AP7353 regulators feature high output voltage accuracy, low RDSON, high PSRR, low output noise, and low quiescent current. Based on a CMOS process, AP7353 regulators include a voltage reference, error amplifier, current limit circuit, and an enable input to turn it on and off. AP7353 is packaged in X1-WLB0707-4 (Type A1), allowing for the smallest footprint and dense PCB layout.
