Overview
The TPL9053 series products are 500-mA high PSRR, ultra-low noise, low dropout linear regulators with high output accuracy. The TPL9053 series products support adjustable output voltage ranges from 0.6 V to 5.3 V with external resistor divider and is stable with 4.7 μF or larger ceramic output capacitor.
The TPL9053 series products have high PSRR with 89 dB at 1kHz and 5.7 μVRMS ultra-low noise. These features make TPL9053 series products very suitable for noise-sensitive applications with high noise from previous stage power supply, such as high-performance analog devices, or high-definition imaging equipment. Output shortage protection and thermal overload protection circuits improves the reliability under heavy load conditions.
The TPL9053 series products provide 2×2 DFN-8 package with guaranteed operating junction temperature range (TJ) from – 40°C to +125°C.
