概述

The TPL9053 is a series of 500-mA high PSRR, ultra-low noise, and low dropout linear regulators with high-output accuracy. The TPL9053 series supports adjustable output voltage ranging from 0.6 V to 5.3 V with an external resistor divider, and is stable with a 4.7-μF or larger ceramic output capacitor.

The TPL9053 series has a high PSRR with 89 dB at 1 kHz and 5.7-μVRMS ultra-low noise. These features make the TPL9053 series very suitable for noise-sensitive applications with high noise from the previous stage power supply, such as high-performance analog devices, or highdefinition imaging equipment. Output shortage protection and thermal overload protection circuits improve reliability under heavy load conditions.

The TPL9053 series provides a DFN2X2-8 package with a guaranteed operating junction temperature range (TJ) from –40°C to +125°C.
