Active High. High = on, low = off. Do not leave floating. – 1 EN1 Enable Input to Regulator 1: Enables regulator 1 output. Active high input. High = on, low = off. Do not leave floating. – 2 EN2 Enable Input to Regulator 2: Enables regulator 2 output. Active high input. High = on, low = off. Do not leave floating. 3 3 CBYP Reference Bypass: Connect external 0.01 µF to GND to reduce output noise. May be left open. 4 5 SW Active high signal drives open-drain N-Channel MOSFET. – 4 ADJ1 Adjust Input (Regulator 1): Connect feedback resistors to program the output voltage for the regulator. 5 6 SET Delay Set Input: Connect external capacitor to GND to set the internal delay for the POR output. When left open, there is no delay. This pin cannot be grounded. 6 7,8 GND Ground: Connect externally to exposed pad. – 9 NGND Ground for the open-drain driver. Tied to the source of the NMOSFET. Tied to GND internally. – 10 ADJ2 Adjust Input (Regulator 2): Connect feedback resistors to program the output voltage for the regulator. 7 11 DRV Open-Drain Output: Capable of sinking 150mA. 8 12 POR Power-On Reset Output: Open-drain output. Active low indicates an output undervoltage condition on regulator 2. 9 13 VOUT2 Output of Regulator 2: 300mA output current 10 14 VOUT1 Output of Regulator 1: 150mA output current EP EP GND Ground: Internally connected to the exposed pad. Connect externally to ground pin. 1 VIN EN BYP SW SET 10 VOUT1 VOUT2 POR DRV GND 9 8 7 6 2 3 4 5 10-Pin 3mm ××××× 3mm MLF™ (ML) (Top View) Pin Configuration |
