Low-Dropout Voltage Regulator, TPS73733DCQ, Texas Instruments

The TPS73733DCQ linear low-dropout (LDO) voltage regulator uses an NMOS pass transistor in a voltage-follower configuration. This topology is relatively insensitive to the output capacitor value and ESR, allowing for 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 for very low dropout. The device uses an advanced BiCMOS process to yield high precision while delivering very low dropout voltages and low ground-pin current. The device incorporates an updated design with new silicon on the latest TI process technology. Current consumption, when not enabled, is less than 20 nA and is designed for portable applications. This device is protected by thermal shutdown and foldback current limit.
