TL7705CPSLE-B Description

Short technical summary and product information.

The UM1540DB-30 is a linear voltage regulator IC manufactured by Union Semiconductor International Limited. This component is designed for power management applications, offering a fixed 3V output voltage with a maximum output current of 300mA. It accepts an input voltage up to 6V and features a very low quiescent current of 1.5 µA, making it suitable for power-sensitive designs.

 

The device operates within a temperature range of -40°C to 125°C. It comes in a compact 4-DFN (1x1) package suitable for surface mounting. The UM1540DB-30 includes over-current and over-temperature protection features for enhanced reliability.

 

Key electrical characteristics include a maximum voltage dropout of 0.33V at 200mA and a Power Supply Rejection Ratio (PSRR) ranging from 56dB to 42dB across the 100Hz to 1kHz frequency range. The component is supplied in tape and reel packaging.
