Adjustable LDOs

TPS76901DBVR General Description

The TPS769xx family of LDO voltage regulators is designed with a focus on low dropout voltage, minimal power consumption, and compact packaging. With their low dropout voltages and ultra-low quiescent current, these regulators outperform traditional LDO regulators, making them suitable for micropower operations and applications where board space is limited. The innovative use of a PMOS pass element instead of the usual PNP pass transistor has significantly reduced the dropout voltage to as low as 71 mV at 100 mA of load current, while also maintaining a stable quiescent current of 28 uA maximum over the entire load current range. These features make the TPS769xx series ideal for use in portable systems like laptops and cell phones, extending the battery operating life of such devices
