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 lo...
