TLV70228DBVT

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TLV70228DBVT is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments. It provides a fixed output voltage of 2.8 V with a maximum continuous output current of 300 mA. The device operates within an input voltage range of 2 V to 5.5 V and features a typical power supply rejection ratio (PSRR) of 68 dB at 1 kHz. Quiescent current is specified at 55 µA, with a maximum dropout voltage of 0.375 V at full load. It includes protection mechanisms such as overcurrent limiting and thermal shutdown.
