SC8863 Datasheet | SEMTECH

DESCRIPTION The SC8863 is a low dropout linear regulator that operates from a +2.5V to +5.5V input range and delivers up to 150m A. A PMOS pass transistor allows the low 110µA supply current to remain independent of load, making these devices ideal for battery operated portable equipment such as cellular phones, cordless phones and personal digital assistants. The SC8863 output voltage can be preset or adjusted with an external resistor divider. Other Features include low powered shutdown, short circuit protection, thermal shutdown protection and reverse battery protection. The SC8863 es in the tiny 5 lead SOT-23 package. Features - Guaranteed 150 m A output current - Fixed or adjustable output - Very small external ponents - Low 75µVRMS output noise - Very low supply current - Thermal overload protection - Reverse battery protection - Low power shutdown - Surface mount packaging (5 pin SOT-23) - Full industrial temperature range APPLICATIONS - Battery Powered Systems - Cellular Telephones - Cordless Telephones - Personal Digital Assistants - Portable Instrumentation - Modems - PCMCIA cards ORDERING INFORMATION Part Number Package (1)(2) BLOCK DIAGRAM SC8863-XXXCSK SOT-23-5 Notes: (1) Where -XXX denotes voltage options.
