LP5990  
Micropower 200mA CMOS Low Dropout Voltage Regulator  
General Description  
Features  
The LP5990 regulator is designed to meet the requirements  
of portable, battery-powered systems providing an accurate  
output voltage, low noise and low quiescent current.  
Operation from 2.2V to 5.5V input  
±1% accuracy over temp range  
Output voltage from 0.8V to 3.6V in 50mV increments  
The LP5990 will provide a 1.8V output from a low input voltage  
of 2.2V and can provide 200mA to an external load.  
30 μA Quiescent current (enabled)  
10nA Quiescent current (disabled)  
160mV dropout at 200mA load  
When switched into shutdown mode via a logic signal at the  
enable pin, the power consumption is reduced to virtually  
60 μVRMSOutput voltage noise  
60 μs start-up time  
500μs shut-down time  
zero.  
Fast shut-down is achieved by the push pull architecture.  
The LP5990 is designed to be stable with space saving 0402  
ceramic capacitors as small as 1µF, this gives an  
overall solution size of < 2.5mm 2.  
PSRR 55 dB at 10 kHz  
Stable with 0402 1.0µF ceramic capacitors  
Logic controlled enable  
Performance is specified for a -40°C to 125°C junction tem-  
perature range.  
Thermal–overload and short–circuit protection  
The device is available in micro SMD Package (0.4mm pitch)  
and is available with 1.2V,1.3V,1.8V,2.8V,3.0V,3.3V and 3.6V  
outputs.Lower voltage options down to 0.8V are available on  
request. For all other output voltage options please contact  
your local NSC sales office.  
Package  
4-Bump micro SMD,0.4mm  
pitch  
866 µm x 917 µm  
(lead free)  
Applications  
Cellular phones  
Hand–held information appliances
