The TPL9032 series products are 300-mA high PSRR, ultra-low noise, 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 is 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 improves the reliability under heavy load conditions.

The TPL9032 series products provide SOT23-5, 1×1 DFN-4, and 0.65×0.65 WLCSP-4 packages with guaranteed operating junction temperature range (TJ) from –40°C to +125°C.
