LP3982  
Micropower, Ultra Low-Dropout, Low-Noise, 300mA  
CMOS Regulator  
General Description  
Features  
n MAX8860 pin, package and spec. compatible  
n LLP space saving package  
n 300mA guaranteed output current  
The LP3982 low-dropout (LDO) CMOS linear regulator is  
available in 1.8V, 2.5V, 2.77V, 2.82V, 3.0V, 3.3V, and adjust-  
able versions. They deliver 300mA of output current. Pack-  
aged in an 8-Pin MSOP, the LP3982 is pin and package  
compatible with Maxim’s MAX8860. The LM3982 is also  
available in the small footprint LLP package.  
@
n 120mV typical dropout 300mA  
n 90µA typical quiescent current  
n 1nA typical shutdown mode  
n 60dB typical PSRR  
n 2.5V to 6V input range  
n 120µs typical turn-on time  
n Stable with small ceramic output capacitors  
The LP3982 suits battery powered applications because of  
its shutdown mode (1nA typ), low quiescent current (90µA  
typ), and LDO voltage (120mV typ). The low dropout voltage  
allows for more utilization of a battery’s available energy by  
operating closer to its end-of-life voltage. The LP3982’s  
PMOS output transistor consumes relatively no drive current  
compared to PNP LDO regulators.  
n 37µV RMS output voltage noise (10Hz to 100kHz)  
n Over temperature/over current protection  
n
2% output voltage tolerance  
This PMOS regulator is stable with small ceramic capacitive  
loads (2.2µF typ).  
Applications  
These devices also include regulation fault detection, a  
bandgap voltage reference, constant current limiting and  
thermal overload protection.  
n Wireless handsets  
n DSP core power  
n Battery powered electronics  
n Portable information appliances
