Overview
The TLV70433DBVT is a low-dropout (LDO) linear voltage regulator produced by Texas Instruments. This device is designed to offer low quiescent current, a wide input voltage range, and low-power operation, making it ideal for battery-powered applications and as a power-management attachment to low-power microcontrollers. The TLV70433DBVT operates over an input voltage range of 2.5 V to 24 V and is stable with any output capacitor greater than or equal to 0.47 μF. It features an internal soft-start to control inrush current and built-in overcurrent protection to safeguard against load shorts or faults.
