SemiconductorLDI1117-05U is a low-dropout (LDO) voltage regulator produced by Diotec semiconductor. The device operates over a wide input voltage range of 4.95V to 20V, and provides an adjustable output between 5.05V and 5mA. It is designed to replace linear fixed- and adjustable-regulators, giving improved flexibility and efficiency. It offers excellent line and load regulation, low noise operation, and an incredibly small footprint thanks to its surface mountable SOT-89 package. The excellent noise performance, low dropout voltage, and very small package size are hallmarks of the LDI1117-05U LDO Voltage Regulator. It is well suited for a range of applications, such as portable medical equipment, audio devices and consumer electronics.
