The LM4817 combines a bridge-connected (BTL) stereo audio power amplifier with a low dropout voltage regulator (LDO). The audio amplifier delivers 1.0W to a 8 load with a less than 1.0% THD+N while operating on a 5V power supply. With VLIM set to 1.0V, the amplifier outputs are clamped to 6Vp-p, ±800mV.
With the LM4817's adjustable low-dropout (LDO) CMOS linear regulator delivers an output current of up to 300mA, has shutdown mode (1nA, typ) low quiescent current (90µA, typ) and LDO voltage (120mV, typ). The regulator is stable with small ceramic capacitive load (2.2µF, typ). The regulator includes regulation fault detection, a bandgap voltage reference, and constant current limiting. It is designed for low power, low current applications that can take advantage of its 300mA output current capability
