The TPS70845PWPG4 is a dual-output low dropout (LDO) voltage regulator designed for split-supply systems. It provides fixed output voltages of 3.3V and 1.2V, with the capability to deliver up to 250 mA from the first regulator and 125 mA from the second. The device features independent enable functions for each output, allowing for flexible power management. This regulator exhibits a low quiescent current of approximately 190 ¬µA at full load and operates with low noise, typically 65 mV RMS without the need for additional bypass capacitors. It includes an integrated supervisory circuit for power-on reset (POR) and a manual reset input, enhancing system reliability. The TPS70845 also incorporates undervoltage lockout (UVLO) protection and thermal shutdown features to safeguard against potential damage. The device is housed in a 20-pin PowerPAD,Ñ¢ TSSOP package, suitable for applications requiring compact design and efficient thermal management. Its specifications make it a viable option for engineers looking for reliable voltage regulation in low-power applications.
