说明

The TPS764xx family of low-dropout (LDO) voltage regulators offers the benefits of a low noise, low-dropout voltage, low-power operation, and miniaturized package. Additionally, they feature low quiescent current when compared to conventional LDO regulators. Offered in 5-terminal small outline integrated-circuit SOT-23 package, the TPS764xx series devices are ideal for low-noise applications, cost-sensitive designs and applications 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\x97typically 300 mV at 150 mA of load current (TPS76433)\x97and is directly proportional to the load current.
