LM4801 Datasheet | National Semiconductor

Description The LM4801 bines a bridge-connected (BTL) stereo audio power amplifier with a low dropout voltage regulator (LDO). The audio amplifier delivers 1.0W to a 8Ω load with a less than 1.0% THD+N while operating on a 5V power supply. With the LM4801’s adjustable low-dropout (LDO) CMOS linear regulator delivers an output current of up to 300m A, has shutdown mode (1n A, typ) low quiescent current (90µA, typ) and LDO voltage (120m V, 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 300m A output current capability. The LM4801 features an externally controlled micropower shutdown mode and thermal shutdown protection. It...
