Description
The TLV741P low-dropout linear regulator (LDO) is a low quiescent current device with excellent line and load transient performance for power-sensitive applications. This device provides a typical accuracy of 1%.
The TLV741P is designed to be stable with a small, 1-µF output capacitor.
The TLV741P provides inrush current control during device power up and enabling. The TLV741P 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 standard DBV (SOT-23) and DQN (X2SON) packages. The TLV741P provides an active pulldown circuit to quickly discharge output loads.
