LP3990  
150mA Linear Voltage Regulator for Digital Applications  
General Description  
Key Specifications  
n Input Voltage Range  
n Output Voltage Range  
n Output Current  
n Output Stable - Capacitors  
n Virtually Zero IQ (Disabled)  
n Very Low IQ (Enabled)  
n Low Output Noise  
n PSRR  
2.0 to 6.0V  
0.8 to 3.3V  
150mA  
The LP3990 regulator is designed to meet the requirements  
of portable, battery-powered systems providing an accurate  
output voltage, low noise, and low quiescent current. The  
LP3990 will provide a 0.8V output from the low input voltage  
of 2V at up to 150mA load current. When switched into  
shutdown mode via a logic signal at the enable pin, the  
power consumption is reduced to virtually zero.  
0.47uF  
<
10nA  
43uA  
150uVRMS  
55dB at 1kHz  
105us  
The LP3990 is designed to be stable with space saving  
ceramic capacitors as small as 0.47µF.  
n Fast Start Up  
Performance is specified for a -40˚C to 125˚C junction tem-  
perature range.  
For output voltages other than 0.8V, 1.35V, 1.5V, 1.8V, 2.5V, Package  
2.8V, or 3.3V please contact your local NSC sales office.  
All available in Lead Free option.  
4 Pin micro SMD  
1 mm x 1.28mm  
Features  
6 pin LLP (SOT23 footprint)  
n 1% Voltage Accuracy at Room Temperature  
n Stable with Ceramic Capacitor  
n Logic Controlled Enable  
SOT23 - 5  
For other package options contact your NSC sales office.  
n No Noise Bypass Capacitor Required  
n Thermal-Overload and Short-Circuit Protection  
Applications  
n Cellular Handsets  
n Hand-Held Information Appliances
