1 / 20 page  LM4801 1W Stereo Audio Amplifier Plus Adjustable LDO General Description The LM4801 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 Ω 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 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 refer- ence, and constant current limiting. It is designed for low power, low current applications that can take advantage of its 300mA output current capability. The LM4801 features an externally controlled micropower shutdown mode and thermal shutdown protection. It also utilizes circuitry that reduces "clicks and pops" during device turn-on and return from shutdown. Boomer audio power amplifiers are designed specifically to use few external components and provide high quality output power in a surface mount package.
