Description

The TPL9032 series products are 300-mA high PSRR,

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

output accuracy. The TPL9032 series products support

both fixed output voltage ranges from 0.9 V to 5 V and

are stable with 1 μF or larger ceramic output capacitor.

The TPL9032 series products have high PSRR with 87.9

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

features make TPL9032 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 improve the reliability under heavy load conditions.

The TPL9032 series products provide SOT23-5,

DFN1x1-4, and WLCSP0.65x0.65-4 packages with

guaranteed operating junction temperature range (TJ) from

–40°C to +125°C.
