Texas Instruments TPS7E72 Low-Dropout Regulators

Texas Instruments TPS7E72 Low-Dropout Regulators are 2.8µA low-quiescent-current devices and support a wide input voltage range of 3V to 30V. These regulators feature an adjustable output range of 1.2V to 28V and a fixed range of 1.8V to 12V, with a load current of up to 300mA. The TPS7E72 LDOs support very tight DC accuracy of ±1.2% over the line, load, and temperature ranges and respond quickly to line and load transients. Protection features include overcurrent, overtemperature, and over-power-delivery protection for reliable operation of the LDO. Typical applications include appliances, home and building automation, retail automation and payment, grid infrastructure, medical applications, and lighting applications.
