Description

The TPL9052 series of products are 500-mA high-PSRR,

ultra-low noise, and low-dropout linear regulators with

high-output accuracy. The TPL9052 series of products

support both fixed output voltage ranging from 1.2 V to

3.6 V and are stable with 1-μF or larger ceramic output

capacitors.

The TPL9052 series of products have high PSRR with

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

features make the TPL9052 series of products very

suitable for noise-sensitive applications with high noise

from the previous stage power supply, such as highperformance

analog devices, or high-definition imaging

equipment.

The TPL9052 series of 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 the circuitry design under

different operating conditions.

The TPL9052 series of products provide SOT23-5

packages with guaranteed operating junction temperature

(TJ) ranging from −40°C to +125°C.
