LP3986  
Dual Micropower 150 mA Ultra Low-Dropout CMOS  
Voltage Regulators in micro SMD Package  
General Description  
The LP3986 is a 150 mA dual low dropout regulator de-  
signed for portable and wireless applications with demand-  
ing performance and board space requirements.  
Features  
n Miniature 8-I/O micro SMD package  
n Stable with 1µF ceramic and high quality tantalum  
output capacitors  
n Fast turn-on  
n Two independent regulators  
n Logic controlled enable  
The LP3986 is stable with a small 1 µF 30% ceramic output  
capacitor requiring smallest possible board space.  
The LP3986’s performance is optimized for battery powered  
systems to deliver ultra low noise, extremely low dropout  
voltage and low quiescent current independent of load cur-  
rent. Regulator ground current increases very slightly in  
dropout, further prolonging the battery life. Optional external  
bypass capacitor reduces the output noise further without  
slowing down the load transient response. Fast start-up time  
is achieved by utilizing a speed-up circuit that actively pre-  
charges the bypass capacitor. Power supply rejection is  
better than 60 dB at low frequencies and 55 dB at 10 kHz.  
High power supply rejection is maintained at low input volt-  
age levels common to battery operated circuits.  
n Over current and thermal protection  
Key Specifications  
n Guaranteed 150 mA output current per regulator  
n 1nA typical quiescent current when both regulators in  
shutdown mode  
n 60 mV typical dropout voltage at 150 mA output current  
n 115 µA typical ground current  
n 40 µV typical output noise  
n 200 µs fast turn-on circuit  
The LP3986 is available in a micro SMD package. Perfor-  
mance is specified for a −40˚C to +125˚C temperature  
range. For single LDO applications, please refer to the  
LP3985 datasheet.  
n −40˚C to +125˚C junction temperature  
Applications  
n CDMA cellular handsets  
n GSM cellular handsets  
n Portable information appliances  
n Portable battery applications
