TPS7A3701DRVR Description

The TPS7A3701DRVR linear low-dropout (LDO) voltage regulator uses an NMOS pass element in a voltage-follower configuration. The TPS7A3701DRVR regulator is relatively insensitive to output capacitor value and ESR, allowing a wide variety of load configurations.
Load transient response is excellent, even with a small 1-μF ceramic output capacitor. The NMOS topology TPS7A3701DRVR also allows very low dropout. TPS7A3701DRVR uses an advanced BiCMOS process to yield high precision while delivering very low dropout voltages and low ground pin current. Current consumption, when not enabled, is under 20nA and ideal for portable applications. TPS7A3701DRVR is protected by thermal shutdown; and foldback current limit.
