Product Overview: Texas Instruments TPS799315DDCR

The Texas Instruments TPS799315DDCR is a high-performance, low-dropout (LDO) linear voltage regulator designed to deliver a stable and precise output voltage. This component is particularly suitable for sensitive applications that require a clean power supply with low noise and low dropout voltage.

Key Features

• Output Voltage: The TPS799315DDCR provides a fixed output voltage of 3.15V, which is ideal for powering a wide range of ICs and microcontrollers that operate at this voltage level.
• High Accuracy: With an impressive output voltage accuracy of ±2%, this LDO ensures reliable performance for precision-dependent applications.
• Low Dropout Voltage: The low dropout voltage of just 40mV at 200mA load allows the regulator to maintain a steady output even when the input voltage is close to the output voltage, enhancing efficiency and battery life in portable devices.
• Low Noise: Offering a low output noise of 30µVRMS, the TPS799315DDCR is an excellent choice for RF and analog circuits where noise can critically impact performance.
• High PSRR: A high power supply rejection ratio (PSRR) of 70dB at 1kHz minimizes the impact of fluctuations in the input voltage on the output, providing a more stable power supply.
• Thermal Protection: The device includes built-in thermal shutdown protection, safeguarding the regulator and the application from damage due to overheating.
• Current Limit Protection: Overcurrent protection is also featured to prevent damage from excessive load conditions.
