3 Description

The TLV713P-Q1 series of low-dropout (LDO) linear regulators are low quiescent current LDOs with excellent line and load transient performance and are designed for power-sensitive applications. These devices provide a typical accuracy of 1%.

The TLV713P-Q1 series of devices is designed to be stable without an output capacitor. The removal of the output capacitor allows for a very small solution size. However, the TLV713P-Q1 series is also stable with any output capacitor if an output capacitor is used.

The TLV713P-Q1 also provides inrush current control during device power-up and enabling. The TLV713P-Q1 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 TLV713P-Q1 series is available in a standard DBV package and provides an active pulldown circuit to quickly discharge output loads. The TLV713P-Q1 is suited for automotive applications because the device is qualified for AEC-Q100 grade 1.
