Description
Low Dropout Voltage: 150 mV typical at 500 mA
High PSRR:
•
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.

8.6-μVRMS Output Voltage Noise
•
•
•
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 high-
performance analog devices, or high-definition imaging
equipment.
Excellent Transient Response
Stable with a 1-μF or Greater Ceramic Output

•
Output Shortage Protection
Over-Temperature and Over-Current Protection
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.
