TPL9053-S

500-mA High PSRR, Ultra-low Noise LDO Regulator

Overview

The TPL9053-S series products are 500-mA high PSRR, ultra-low noise, and low dropout linear regulators with high- output accuracy. The TPL9053-S series products support 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-S series products have high PSRR with 89 dB at 1 kHz and 5.7-μVRMS ultra-low noise. These features make TPL9053-S series products very suitable for noise- sensitive applications with high noise from the previous stage power supply, such as high-performance analog devices, or high-definition imaging equipment. Output shortage protection and thermal overload protection circuits improve the reliability under heavy load conditions.

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