5 / 13 page MP20045 – LOWER NOISE, 1A LINEAR REGULATOR MP20045 Rev. 1.0 www.MonolithicPower.com 5 10/13/2010 MPS Proprietary Information. Unauthorized Photocopy and Duplication Prohibited. © 2010 MPS. All Rights Reserved. PIN DESCRIPTION QFN8 (3X3) Pin # SOIC8E Pin # Name Description 1, 2 7, 8 VIN Regulator Input. Supply voltage ranges from +2.5V to 5.5V. Bypass with 2.2µF capacitor. These pins must be externally connected for proper operation even if they are internally connected. 3, 4 1, 2 VOUT Regulator output. Bypass with a 2.2µF low-ESR capacitor to GND. Connect all the pin together externally. 5 3 FB Feedback Input. For the adjustable output version, connect FB to the center point of the external resistor divider. The feedback threshold voltage is 1.5V. For the fixed output version, connect FB to the output directly. 6 4 GND Expose d pad Ground. Connect exposed pad to GND plane for optimal thermal performance. 7 5 PG Open-drain power-good (PG) output. 8 6 EN Positive polarity enable (EN) input. Regulator Enable Control Input. Drive EN above 1.5V to turn on the MP20045. Drive EN below 0.4V to turn it off. Do not float the EN pin. |
