The L4949ED from STMicroelectronics is a monolithic integrated 5V voltage regulator featuring a very low dropout output. It is designed for supplying microcomputer-controlled systems, particularly in automotive applications.
Key electrical specifications include an operating DC supply voltage range of 5V to 28V, with transient supply voltage capability up to 40V. The regulator offers a high-precision standby output voltage of 5V ±1% and an output current capability of up to 100mA. A very low dropout voltage of less than 0.5V at 100mA is achieved.
Additional integrated functions include a reset circuit that senses the output voltage, a programmable reset pulse delay with an external capacitor, and a voltage sense comparator. Protection features include thermal shutdown and short circuit protection. The device operates over a temperature range of -40°C to 125°C.
The L4949ED is available in an 8-SOIC surface mount package.
