Texas Instruments  TPS73733DRVR

The TPS737xx family of linear low-dropout (LDO) voltage regulators uses an NMOS passelement in a voltage-follower configuration. This topology is relatively insensitive to outputcapacitor value and ESR, allowing a wide variety of load configurations. Load transient response isexcellent, even with a small 1-µF ceramic output capacitor. The NMOS topology also allows very lowdropout.

The TPS737xx family uses an advanced BiCMOS process to yield high precision whiledelivering very low dropout voltages and low ground pin current. Current consumption, when notenabled, is less than 20 nA and ideal for portable applications. These devices areprotected by thermal shutdown and foldback current limit.

Forapplications that require higher output voltage accuracy, consider TI’sTPS7A37xx family of 1% overall accuracy,1-A low-dropout voltage regulators.
