The MIC5249-1.8YMM is a CMOS linear voltage regulator designed to provide a stable 1.8V output with a maximum output current of 300mA. It features a low dropout voltage of approximately 340mV at full load, making it suitable for battery-powered and noise-sensitive applications. The device offers 1% initial output voltage accuracy and includes a power-on reset (POR) function with an adjustable delay, which can be set using an external capacitor. This regulator operates with low-ESR ceramic capacitors, allowing for reduced board space, which is advantageous in compact designs such as cellular phones and PDAs. Additional features include thermal shutdown, current limit protection, and a logic-compatible enable pin for easy integration into various circuits. The MIC5249-1.8YMM is housed in an 8-pin MSOP package and is rated for operation over a temperature range of -40¬8C to +125¬8C.
