特性特點

The TPL740 series products are high performance and low dropout linear regulators. The TPL740 series products support maximum 500 mA output current with low quiescent current and high PSRR. The TPL740 series products is stable with ceramic output capacitor from 2.2 μF to 10 μF.

The TPL740 series products have a high PSRR with 60 dB at 1 KHz. This feature makes TPL740 series products very suitable for power-sensitive applications with high noise from previous stage power supply. As low as 49 μA quiescent current and only 20 nA shutdown current makes the TPL740 series products ideal choices for portable devices with battery power supply. Current-limit foldback and thermal overload protection circuits improves the reliability under heavy load conditions.

The TPL740 series products provide several output voltage version options including fixed version and adjustable version with ±2% output voltage accuracy over operating conditions. The TPL740 series products are guaranteed over operating temperature range from –40°C to +85°C.
