TPS79912DRVR - Low-Dropout (LDO) Linear Regulator by Texas Instruments

The TPS79912DRVR from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed to deliver a fixed output voltage of 1.2V with an input voltage range from 2.7V to 6.5V. This regulator is capable of supplying up to 200mA of output current, making it an ideal choice for power-sensitive applications that require a stable and precise voltage supply.

Encased in a compact 6-pin SON package, the TPS79912DRVR boasts a low quiescent current of only 40µA at no load, which significantly improves the battery life of portable devices. Its low dropout voltage, typically just 40mV at a 200mA load, ensures efficient operation even when the input voltage is close to the output voltage, which is particularly beneficial for battery-operated equipment.

The TPS79912DRVR incorporates several features that enhance the safety and reliability of the end application. These include built-in thermal shutdown and overcurrent protection mechanisms that safeguard the device and the downstream components from damage due to excessive heat or current. Additionally, the regulator offers a high power supply rejection ratio (PSRR) which minimizes the impact of supply voltage variations on the output voltage, thereby ensuring a stable and clean power supply.

Key features of the TPS79912DRVR include:

• Fixed Output Voltage: 1.2V
• Output Current: Up to 200mA
• Low Dropout Voltage: 40mV (typical) at 200mA load
• Low Quiescent Current: 40µA (typical) at no load
• Input Voltage Range: 2.7V to 6.5V
• High PSRR: 70dB at 1kHz
• Thermal Shutdown and Overcurrent Protection
