Note 2: Additional information on lead temperature and pad temperature may be obtained by contacting CR PowTech Note 3: Like the Absolute Maximum power dissipation, the maximum power dissipation for operation depends on the ambient temperature. Note 4: The target output voltage, which is labeled V OUT(nom), is the desired voltage option. Note 5: All limits are guaranteed. All electrical characteristics having room-temperature limits are tested during production with T J = 25 C or correlated using Statistical Quality Control (SQC) methods. All hot and cold limits are guaranteed by correlating the electrical characteristics to process and temperature variations and applying statistical process control.

5 SIMPLIFIED BLOCK DIAGRAM PT5110 V IN V OUT Current Sense & Current Limit R1 Bandgap Reference 1.25V Thermal Shutdown R2 GND Figure1. Graph the PT5110 major functional blocks In Figure 1, the block of Bandgap Reference provides the reference voltage of the LDO. The op amp block is used as the error amplifier of the LDO by compare the reference with the output feedback voltages. Its output controls the gate of a large PMOS driver and hereby adjusts the output voltage. The resistor R 1 and R 2 form a voltage divider to provide the feedback voltage. The Current Sense & Limit block senses the LDO output current and limits the output current from being too high. This is mostly a short circuit protection feature.
