The 40-V internal • Low Shutdown Current (< 1 µA) switch makes these solutions perfect for boosting to • 5-Lead SOT-23 Package voltages of 16 V or greater. • Uses Tiny Capacitors and Inductors These parts have a logic-level shutdown pin that can • Cycle-by-Cycle Current Limiting be used to reduce quiescent current and extend • Internally Compensated battery life. Protection is provided through cycle-by-cycle current 2 Applications limiting and thermal shutdown. Internal compensation • White LED Current Source simplifies design and reduces component count. • PDA’s and Palm-Top Computers Device Information(1) • Digital Cameras PART NUMBER PACKAGE BODY SIZE (NOM) • Portable Phones and Games LM2733 SOT-23 (5) 2.90 mm x 1.60 mm • Local Boost Regulator (1) For all available packages, see the orderable addendum at the end of the datasheet.
