Description

The TLV741P low-dropout (LDO) linear regulator is a low quiescent current LDO with excellent line and load transient performance and is designed for power-sensitive applications. This device provides a typical accuracy of 1%.

The TLV741P device is designed to be stable with a small, 1-µF output capacitor.

The TLV741P device provides inrush current control during device power up and enabling. The TLV741P device limits the input current to the defined current limit to avoid large currents from flowing from the input power source. This functionality is especially important in battery-operated devices.

The TLV741P is available in a standard DBV (SOT-23) package. The TLV741P provides an active pulldown circuit to quickly discharge output loads.
