描述 Description

The TPL9053-S series products are 500-mA high PSRR,

ultra-low noise, and low dropout linear regulators with highoutput 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 noisesensitive 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.
