TPL820F50-3TR High Voltage and Low Quiescent Current LDO

　　The TPL820 series products are high-performance and low dropout linear regulators.The TPL820 series products support a maximum 42 V input voltage and 180 mA output current with low quiescent current and high PSRR.The TPL820 series products are stable with a 2.2μF to 22μF output capacitor,and a 4.7μF ceramic capacitor is recommended.The TPL820 series products have a high PSRR with 73 dB at 100 Hz.This feature makes TPL820 series products very suitable for power-sensitive applications with high noise from the previous stage power supply.2μA ultra-low quiescent current makes the TPL820 series products ideal choices for portable devices with battery power supply.Current-limit and thermal overload protection circuits improve the reliability under heavy load conditions.The TPL820 series products provide fixed output voltage options from 2.8 V to 5 V with±2%voltage accuracy over operating conditions.The TPL820 series products are guaranteed over the junction temperature range from−40°C to+125°C.
