Description

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.

Or connect this pin to the IN pin for self-bias applications. below VOUT (NOM) + VDO or 1.5 V, the output pin tracks the input voltage minus the dropout voltage based on the load current. The TPL5031 series integrates an internal current limit that helps to protect the regulator during over-load fault conditions. limit mode, and the output voltage falls to VOUT = ICL × RLOAD.

The TPL5031 series integrates short-circuit protection. When the output pin is shorted to the ground, the output current of the TPL5031 series is limited to a typical value of ISC. Thermal Shutdown During normal operation, the LDO junction temperature should not exceed 125°C. When the junction temperature exceeds the thermal shutdown threshold, the LDO shuts down the output immediately. Until the junction temperature falls below the thermal shutdown threshold minus thermal shutdown hysteresis, the output turns on again.

  • Both input capacitors and output capacitors must be placed as close to the device pins as possible.
  • It is recommended to bypass the input pin to the ground with a 0.1-μF bypass capacitor. The loop area formed by the bypass capacitor connection, the IN pin, and the GND pin of the system must be as small as possible.
  • It is recommended to use wide and thick copper to minimize the I×R drop and heat dissipation. TPL5031 Series 300-mA Output, High PSRR, Low-Dropout Linear Regulator www.3peak.com 13 / 18 DA20241101A2
