4.6 TPS737

The TPS737xx family of linear low-dropout (LDO) voltage regulators uses an NMOS pass element in a voltage-follower configuration. This topology 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 also allows very low dropout.

The TPS737xx family 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 less than 20 nA and ideal for portable applications. These devices are protected by thermal shutdown and foldback current limit.
