With a wide input range from 4.5V-42V, it is • Output Voltage Range of 0.765V to 34V suitable for a wide range of applications such as • Output Current up to 0.3A power conditioning from unregulated sources. They feature a low RDSON (0.9Ω typical) internal switch for • 1.25 MHz Switching Frequency maximum efficiency (85% typical). Operating • Low Shutdown Iq, 16 µA Typical frequency is fixed at 1.25 MHz allowing the use of • Short Circuit Protected small external components while still being able to have low output voltage ripple. Soft-start can be • Internally Compensated implemented using the shutdown pin with an external • Soft-Start Function RC circuit allowing the user to tailor the soft-start time • Thin SOT-23-6 Package (2.97 x 1.65 x 1mm) to a specific application. • Fully Enabled for WEBENCH® Power Designer The LMR14203 is optimized for up to 300 mA load current. PERFORMANCE BENEFITS Additional features include: thermal shutdown, VIN • Tight Accuracy for Powering Digital ICs under-voltage lockout, and gate drive under-voltage • Extremely Easy to Use lockout. The LMR14203 is available in a low profile SOT-6L package. • Tiny Overall Solution Reduces System Cost APPLICATIONS • Point-of-Load Conversions from 5V, 12V, and 24V Rails • Space Constrained Applications • Battery Powered Equipment • Industrial Distributed Power Applications • Power Meters • Portable Hand-Held Instruments System Performance Efficiency vs Load Current Efficiency vs Load Current VIN = 12V, VOUT = 1.2V and 3.3V VIN = 24V, VOUT = 1.2V and 3.3V 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
