PIN DESCRIPTIONS PIN NAME DESCRIPTION 1, 2 SW3 Switch Node for REG3. 3 GP3 Power Ground for REG3. Connect GP14, GP2, GP3, and GA together at a single point as close to the IC as possible. 4 OUT10 REG10 output. Bypass it to ground with a 2.2µF capacitor. 5 OUT11 REG11 output. Bypass it to ground with a 2.2µF capacitor. 6 INL3 Power input for REG10, REG11 and REG12. 7 OUT12 REG12 output. Bypass it to ground with a 2.2µF capacitor. 8 VSELR2 Output Voltage Selection for REG2. Drive to logic low to select default output voltage. Drive to logic high to select secondary output voltage. 9 nPBSTAT Active-Low Open-Drain Push-Button Status Output. nPBSTAT is asserted low whenever the nPBIN is pushed, and is high-Z otherwise. 10 GP2 Power ground for REG2. Connect GP14, GP2, GP3, and GA together at a single point as close to the IC as possible. 11, 12 SW2 Switch Node for REG2. 13, 14 VP2 Power input for REG2. Bypass to GP2 with a high quality ceramic capacitor placed as close to the IC as possible. 15 OUT2 Output Voltage Sense for REG2. 16 PWREN Power enable input. 17 REFBP Reference Bypass. Connect a 0.047μF ceramic capacitor from REFBP to GA. This pin is discharged to GA in shutdown. 18 INL2 Power Input for REG8, REG9. 19 OUT9 REG9 output. Bypass it to ground with a 2.2µF capacitor. 20 GA Analog Ground. 21 OUT4 Output voltage sense for REG4. 22 OUT8 REG8 output.
