42-V Input, 180-mA Output High Voltage and Low Quiescent

◉ The TPL820 is a series of high-performance and low-dropout linear regulators. The TPL820 series supports a maximum 42-V input voltage and a 180-mA output current with low quiescent current and high PSRR. The TPL820series is stable with a 2.2-μF to 22-μF output capacitor，and a 4.7-μF ceramic capacitor is recommended.

◉ The TPL820 series has a high PSRR with 73 dB at 100Hz. This feature makes the TPL820 series very suitable for power-sensitive applications with high noise from the previous stage power supply. A 2-μA ultra-low quiescent current makes the TPL820 series ideal for portable devices with a battery power supply. Current-limit and thermal overload protection circuits improve reliability under heavy load conditions.

◉ The TPL820 series provides fixed output voltage options from 3.0 V to 5 V with ±2% voltage accuracy over operating conditions. The TPL820 series is guaranteed over the junction temperature range from −40°C to +125°C.
