Overview
The TPL740 is a series of high-performance and lowdropout linear regulators. The TPL740 series supports a maximum 500-mA output current with low-quiescent current and high PSRR. The TPL740 series is stable with ceramic output capacitors from 2.2 μF to 10 μF.
The TPL740 series has a high PSRR with 60 dB at 1 kHz. This feature makes the TPL740 series very suitable for power-sensitive applications with high noise from the previous stage power supply. A quiescent current of as low as 49 μA and only 20-nA shutdown current make the TPL740 series ideal for portable devices with battery power supplies. The current limit foldback and thermal overload protection circuits improves the reliability under heavy load conditions.
The TPL740 series provides several output voltage options including the fixed and adjustable versions with ±2% output voltage accuracy over operating conditions. The TPL740 series is guaranteed over the junction temperature range from −40°C to +125°C.
