TPL820

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

Overview

The TPL820 series products are high-performance and low dropout linear regulators. The TPL820 series products support a maximum 42V input voltage and 180mA 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 73dB at 100Hz. 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 2.8V to 5V with ±2% voltage accuracy over operating conditions. The TPL820 series products are guaranteed over the junction temperature range from −40°C to +125°C.
