TPS7E81/TPS7E81-Q1 LDO Linear Voltage Regulators

Texas Instruments TPS7E81/TPS7E81-Q1 Low-Dropout (LDO) Linear Voltage Regulators are low quiescent current devices and support a wide input voltage range of 3V to 40V. The wide output range is 1.2V to 38V for the adjustable configuration, 1.8V to 12V for the fixed configuration, and a load current of up to 150mA is supported. With a quiescent current of only 2.8µA at no load, the device is designed to power microcontrollers and other low-power loads in battery-powered applications.
