Description

The TPL9052 series products are 500-mA high PSRR,

ultra-low noise, low dropout linear regulators with

high output accuracy. The TPL9052 series products

support both fixed output voltage ranges from 0.9 V

to 5 V and is stable with 1 μF or larger ceramic output

capacitor.

The TPL9052 series products have high PSRR with

88 dB at 10 kHz and 8.6 μVRMS ultra-low noise.

These features make TPL9052 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.

The TPL9052 series products integrate protection

features: output reverse current protection, output

shortage protection, over-temperature protection and

overload protection. All these features significantly

improve the system reliability and simplify circuitry

design under different operating conditions.

The TPL9052 series products provide SOT23-5, and

DFN1X1-4 packages with guaranteed operating

junction temperature range (TJ) from ?40°C to

+125°C.
