TPS76301DBVT

The TPS76301DBVT is a low-dropout (LDO) Voltage Regulator offers the benefits of low-dropout voltage, low-power operation and miniaturized packaging. This regulator features low dropout voltages and quiescent currents compared to conventional LDO regulator. Offered in 5-terminal small outline integrated-circuit, the device is ideal for cost-sensitive designs and where board space is at a premium. A combination of new circuit design and process innovation has enabled the usual PNP pass transistor to be replaced by a PMOS pass element. Because the PMOS pass element behaves as a low-value resistor, the dropout voltage is very low - typically 300mV at 150mA of load current. Since the PMOS pass element is a voltage-driven device, the quiescent current is very low and is stable over the entire range of output load current. It is intended for use in portable systems, the low-dropout voltage feature and low-power operation result in a significant increase in system battery operating life.
