SNVS438B –APRIL 2007–REVISED DECEMBER 2007  
LP5990 Micropower 200mA CMOS Low Dropout Voltage Regulator  
Check for Samples: LP5990  
1
FEATURES  
DESCRIPTION  
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  
60 μVRMSOutput Voltage Noise  
60 μs Start-Up Time  
When switched into shutdown mode via a logic signal  
at the enable pin, the power consumption is reduced  
to virtually  
zero.  
500μs Shut-Down Time  
PSRR 55 dB at 10 kHz  
Fast shut-down is achieved by the push pull  
architecture.  
Stable with 0402 1.0µF Ceramic Capacitors  
Logic Controlled Enable  
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.  
Thermal–Overload and Short–Circuit  
Protection  
Performance is specified for a -40°C to 125°C  
junction temperature range.  
APPLICATIONS  
•
•
Cellular Phones  
The device is available in DSBGA Package (0.4mm  
pitch)  
and  
is  
available  
with  
Hand–Held Information Appliances  
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 TI sales office.
