Description

The NCP502/A series of fixed output linear regulators are designed for handheld communication equipment and portable battery powered applications  which  require  low  quiescent.  The  NCP502/A  series features an ultra−low quiescent current of 40
A. Each device contains a voltage reference unit, an error amplifier, a PMOS power transistor, resistors for setting output voltage, current limit, and temperature limit protection circuits.
The NCP502/A has been designed to be used with low cost ceramic capacitors.  The  device  is  housed  in  the  micro−miniature SC70−5 surface mount package. Standard voltage versions are 1.5 V, 1.8 V,2.5 V, 2.7 V, 2.8 V, 3.0 V, 3.3 V, 3.5 V, and 5.0 V. Other voltages are available in 100 mV steps.
