The NCP699 series of fixed output LDO’s are designed for handheld communication equipment and portable battery powered applications which require low quiescent current. The NCP699 series features a very low ground current of 40 A， independent of load current. Each device contains a voltage reference unit， an error amplifier， a PMOS power transistor， internal resistors for setting output voltage， current limit， and temperature limit protection circuits. The NCP699 has been designed to be used with low cost capacitors. The device is housed in the micro?miniature TSOP?5 surface mount package. Standard voltage versions are 1.3， 1.4， 1.5， 1.8， 2.5， 2.8， 2.9， 3.0， 3.1， 3.3， 3.4， 4.5 and 5.0 V. Other voltages are available in 100 mV steps.
