500-mA, low-IQ, low-dropout voltage regulator with enable

TPS73501DRBT General Description

With a dropout voltage as low as 280 mV at a 500-mA output, the TPS73501DRBT is stable with ceramic capacitors and utilizes advanced BiCMOS technology for enhanced efficiency. Its precision voltage reference and feedback loop contribute to an overall accuracy of 2% under varying load, line, process, and temperature conditions. The device is fully operational within a wide temperature range from -40°C to +125°C
