The TPS70345 is a dual output low dropout (LDO) voltage regulator from Texas Instruments. It provides two regulated outputs: 3.3V on Regulator 1 with up to 1A output current, and 1.2V on Regulator 2 with up to 2A output current. The device features an ultralow quiescent current of 185 µA typical, reducing power consumption in standby modes. The input current during standby is only 2 µA.
Output noise is typically 78 µVRMS without a bypass capacitor, making it suitable for noise-sensitive applications. The regulator maintains 2% accuracy over load and temperature variations. An open-drain power-on reset output with a 120 ms delay provides system initialization sequencing.
The TPS70345 operates over an extended temperature range of -55°C to 125°C. It is packaged in a 24-pin PowerPAD TSSOP package, which enhances thermal dissipation for reliable operation in demanding environments.
