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.
Features Pb−Free Packages are Available Low Quiescent Current of 40 �A Typical Excellent Line and Load Regulation Low Output Voltage Option Output Voltage Accuracy of 2.0% Industrial Temperature Range of −40°C to 85°C NCP502: 1.3 V Enable Threshold High, 0.3 V Enable Threshold Low NCP502A: 1.0 V Enable Threshold High, 0.4 V Enable Threshold Low
