4 / 12 page MP2030 – 3A VERY LOW DROPOUT LINEAR REGULATOR MP2030 Rev. 0.91 www.MonolithicPower.com 4 10/10/2011 MPS Proprietary Information. Unauthorized Photocopy and Duplication Prohibited. © 2011 MPS. All Rights Reserved. PIN FUNCTIONS QFN3X3 10pins Pin # Name Description 9, 10 OUT Regulator Output. OUT is the output of the linear regulator, By pass OUT to GND with a 4.7µF or greater capacitor. 3 BIAS Bias Voltage. Bypass to ground with a 1uF or greater capacitor for maximum output current the VIN>0.2V+VOUT and VBIAS>2V+VOUT. 8 FB Feedback Input. Connect a resistive voltage divider from OUT to FB to set the output voltage. OUT feedback threshold is 0.5V. 7 EN Enable Input. Drive EN high to turn on the MP2030, drive EN low to turn it off. For automatic startup, connect EN to IN. 5 GND Ground, exposed pad. 1, 2 IN Power Source Input. IN supplies power to the load at the output (through the power transistor). Bypass IN to GND with a 1µF or greater capacitor. 4 PGOOD Open drain output. High indicated VOUT> 90% final value. 6 BYPASS Connect a 1nF to this pin. Do not load this pin resistively. QFN5x5 32pins Pin # Name Description 20, 21,22, 23 VOUT Regulator Output. OUT is the output of the linear regulator, By pass OUT to GND with a 4.7µF or greater capacitor. 6 BIAS Bias Voltage. Bypass to ground with a 1uF or greater capacitor. 19 FB Feedback Input. Connect a resistive voltage divider from OUT to FB to set the output voltage. OUT feedback threshold is 0.5V. 18 EN Enable Input. Drive EN high to turn on the MP2030, drive EN low to turn it off. For automatic startup, connect EN to IN. 8 GND Ground, exposed pad. 2, 3, 4, 5 VIN Power Source Input. IN supplies power to the load at the output (through the power transistor). Bypass IN to GND with a 1µF or greater capacitor. 7 PGOOD Open drain output. High indicated VOUT> 90% final value. 17 BYPASS Connect a 1nF to this pin. Do not load this pin resistively. 1, 9, 10, 11, 12, 13, 14, 15, 16, 24, 25, 26, 27, 28, 29, 30, 31, 32 NC These are no connection pins. |
