LP3996  
Dual Linear Regulator with 300mA and 150mA Outputs  
and Power-On-Reset  
General Description  
Key Specifications  
n Input Voltage Range  
2.0V to 6.0V  
210mV at 300mA  
35µA  
The LP3996 is a dual low dropout regulator with power-on-  
reset circuit. The first regulator can source 150mA, while the  
second is capable of sourcing 300mA and has a power-on-  
reset function included.  
n Low Dropout Voltage  
n Ultra-Low IQ (enabled)  
n Virtually Zero IQ (disabled)  
<
10nA  
The LP3996 provides 1.5% accuracy requiring an ultra low  
quiescent current of 35µA. Separate enable pins allow each  
output of the LP3996 to be shut down, drawing virtually zero  
current.  
Package  
All available in Lead Free option.  
The LP3996 is designed to be stable with small footprint  
ceramic capacitors down to 1µF. An external capacitor may  
be used to set the POR delay time as required.  
10 pin LLP 3mm x 3mm  
For other package options contact your NSC sales office.  
The LP3996 is available in fixed output voltages and comes  
in a 10 pin, 3mm x 3mm, LLP package. .  
Applications  
n Cellular Handsets  
n PDA’s  
Features  
n Wireless Network Adaptors  
n 2 LDO Outputs with Independent Enable  
n 1.5% Accuracy at Room Temperature, 3% over  
Temperature  
n Power-On-Reset Function with Adjustable Delay  
n Thermal Shutdown Protection  
n Stable with Ceramic Capacitors
