NCP154 Voltage Regulator - Dual, Low I , Low Dropout, Q Dual Input 300 mA NCP154 IN1 ENABLE THERMAL EN1 LOGIC SHUTDOWN BANDGAP MOSFET REFERENCE DRIVER WITH CURRENT LIMIT OUT1 ACTIVE DISCHARGE EN1 GND IN2 ENABLE THERMAL EN2 LOGIC SHUTDOWN BANDGAP MOSFET REFERENCE DRIVER WITH CURRENT LIMIT OUT2 ACTIVE DISCHARGE EN2 GND Figure 2. Simplified Schematic Block Diagram Table 1. PIN FUNCTION DESCRIPTION Pin No. Pin Name Description 1 GND Power supply ground. Soldered to the copper plane allows for effective heat dissipation. 2 OUT1 Regulated output voltage of the first channel. A small 1 F ceramic capacitor is needed from this pin to ground to assure stability. 3 OUT2 Regulated output voltage of the second channel. A small 1 F ceramic capacitor is needed from this pin to ground to assure stability. 4 GND Power supply ground. Soldered to the copper plane allows for effective heat dissipation. 5 EN2 Driving EN2 over 0.9 V turns-on OUT2. Driving EN below 0.4 V turns-off the OUT2 and activates the active discharge. 6 IN2 Inputs pin for second channel. It is recommended to connect 1 F ceramic capacitor close to the device pin. 7 IN1 Inputs pin for first channel. It is recommended to connect 1 F ceramic capacitor close to the device pin. 8 EN1 Driving EN1 over 0.9 V turns-on OUT1. Driving EN below 0.4 V turns-off the OUT1 and activates the active discharge. EP Exposed pad must be tied to ground. Soldered to the copper plane allows for effective thermal dissipation.
