Overview
The TPL5031 is a series of 300-mA high PSRR, low noise, and low dropout linear regulators with high output accuracy. The TPL5031 series supports both fixed output voltage ranges from 0.75 V to 3.6 V and adjustable output voltage ranges from 0.75 V to 5 V with an external resistor divider. The TPL5031 is stable with a 4.7-μF or larger ceramic output capacitor.
The TPL5031 series has a high PSRR with 70 dB at 1 kHz. This feature makes the TPL5031 series very suitable for power-ripple-sensitive applications with high noise from the previous stage power supply, such as high-performance analog devices, or high-definition imaging equipment. The output shortage protection and thermal overload protection circuits improve reliability under heavy load conditions.
The TPL5031 series provides SOT23-5 and DFN1×1-4 packages with a guaranteed operating junction temperature range from −40°C to +125°C.
