Overview of TLV74318PDQNR

The TLV74318PDQNR is a member of the TLV743P series, offering an ultra-small, low quiescent current LDO solution capable of delivering 300 mA with exceptional line and load transient performance. Its stable operation with a 1µF output capacitor makes it a great fit for applications with space constraints. The device includes foldback current control during power up and enabling, a valuable feature for battery-operated devices, and features an active pulldown circuit for quick discharge of output loads when disabled. Packaged in the X2SON (4) package, the TLV74318PDQNR ensures easy integration and offers a reliable power solution for a wide range of applications
