500mA SmartLDO With Power Up Signal Sequencing PRELIMINARY - January 17, 2000 TM SC1545 TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION The SC1545 was designed for instantly available motherboard applications. As part of the Semtech family of SmartLDO’s it provides additional control functions not available in a standard LDO. The device provides the capability to control three separate supplies. There is an on-board 500mA, 2.5V LDO with current limit protection, and drive pins for an N-channel MOSFET and a P-channel MOSFET. Internal logic circuitry ensures that the system starts up in a controlled manner, and that the correct outputs are enabled during specific sequences of BF_CUT and SLP.
