TPL730

300 mA output, High PSRR, Low-Dropout Linear Regulator

Overview

The TPL730 series products are high-performance and low-dropout linear regulators. The TPL730 series products support a maximum 300 mA output current with low-quiescent current and high PSRR. The TPL730 series products are stable with ceramic output capacitors from 2.2 μF to 10 μF.

The TPL730 series products have a high PSRR with 60 dB at 1 kHz. This feature makes TPL730 series products very suitable for power-sensitive applications with high noise from the previous stage power supply. As low as 49 μA quiescent current and only 20 nA shutdown current makes the TPL730 series products ideal choices for portable devices with battery power supply. Current limit foldback and thermal overload protection circuits improve reliability under heavy load conditions.

The TPL730 series products provide several output voltage version options including fixed version and adjustable version with ±2% output voltage accuracy over operating conditions. The TPL730 series products are guaranteed over the junction temperature range from –40°C to +125°C.
