The LMR14203XMKE/NOPB is a SIMPLE SWITCHER® 42Vin 0.3A step-down Voltage Regulator suitable for a wide range of applications such as power conditioning from unregulated sources. This regulator features a low RDSON (0.9R typical) internal switch for maximum efficiency (85% typical). Operating frequency is fixed at 1.25MHz allowing the use of small external components while still being able to have low output voltage ripple. Soft-start can be implemented using the shutdown pin with an external RC circuit allowing the user to tailor the soft-start time to a specific application. The LMR14203 is optimized for up to 300mA load current. Additional features include thermal shutdown, VIN under-voltage lockout and gate drive under-voltage lockout.
● Short-circuit protection
● Internally compensated
● Soft-start function
● Fully enabled for WEBENCH® power designer
● Green product and no Sb/Br
●This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
