Simplified Block Diagram PIN FUNCTION DESCRIPTIONS Pin Pin Name Function Description 1 GND1 Ground of the 1st LDO 2 En1 Enables the 1st LDO A 900 mV level on this pin is sufficient to start this LDO. A 150 mV shuts it down. 3 GND2 Ground of the 2nd LDO 4 En2 Enables the 2nd LDO A 900 mV level on this pin is sufficient to start this LDO. A 150 mV shuts it down. 5 V 2nd LDO V pin This pin brings the power to the 1st LDO and requires adequate decoupling. cc2 cc 6 V Shuts or wakesup the IC This pin requires a 1.0 F output capacitor to be stable. out2 7 V 1st LDO V pin This pin brings the power to the 1st LDO and requires adequate decoupling. cc1 cc 8 V Delivers the output voltage This pin requires a 1.0 F output capacitor to be stable. out1 MAXIMUM RATINGS Value Rating Pin Symbol Min Max Unit Power Supply Voltage 1 V 12 V in ESD Capability, HBM Model All Pins 1.0 kV ESD Capability, Machine Model All Pins 200 V Maximum Power Dissipation P Internally Limited W D NW Suffix, Plastic Package Thermal Resistance JunctiontoAir R 240 C/W J A Operating Ambient Temperature T 40 to +85 C A Maximum Junction Temperature (Note 1) T 150 C Jmax Maximum Operating Junction Temperature (Note 2) T 125 C J Storage Temperature Range T 60 to +150 C stg Stresses exceeding Maximum Ratings may damage the device.
