特性特点

The TPL820 series products are high performance and low dropout linear regulators. The TPL820 series products support maximum 42 V input voltage and 200 mA output current with low quiescent current and high PSRR. The TPL820 series products is stable with 2.2 μF or higher output capacitor, and 4.7 μF 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 previous stage power supply. 2 μA 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 improves the reliability under heavy load conditions.

The TPL820 series products provide fixed output voltage options from 1.2 V to 5 V with ±2% voltage accuracy over operating conditions. The TPL820 series products are guaranteed over ambient temperature range from –40°C to +85°C.
