Texas Instruments TPS737 Linear Low-Dropout (LDO) Voltage Regulators use an NMOS pass transistor in a voltage-follower configuration. This topology is relatively insensitive to the ESR and output capacitor value. This feature allows for various load configurations. The load transient response is excellent even with a small 1µF ceramic output capacitor. The NMOS topology also allows for a very low dropout.
The TPS737 uses an advanced BiCMOS process to yield high precision. This process delivers very low dropout voltages and low ground pin current. All part numbers with the M3 suffix use an updated design on the current TI process technology. When not enabled, current consumption is less than 20nA. This feature is designed for portable applications. A thermal shutdown and foldback current limit protect the device.
For applications that require higher output voltage accuracy, the user should consider Texas Instruments TPS7A37 1% overall accuracy, 1A low-dropout voltage regulator.
