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 a wide output range from 1.2V to 28V for adjustable configuration, 1.8V to 12V for fixed configuration, and up to 300mA load current. 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.
