FEATURES  
DESCRIPTION  
The LP3982 low-dropout (LDO) CMOS linear  
regulator is available in 1.8V, 2.5V, 2.77V, 2.82V,  
3.0V, 3.3V, and adjustable versions. They deliver 300  
mA of output current. Packaged in an 8-Pin VSSOP,  
the LP3982 is pin and package compatible with  
Maxim's MAX8860. The LM3982 is also available in  
the small footprint WSON package.

120 mV Typical Dropout @ 300 mA  
90 μA Typical Quiescent Current  
1 nA Typical Shutdown Mode  
60 dB Typical PSRR  
The LP3982 suits battery-powered applications  
because of its shutdown mode (1nA typ), low  
quiescent current (90 μA typ), and LDO voltage (120  
mV 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.  
2.5V to 6V Input Range  
120μs Typical Turn-on Time  
Stable with Small Ceramic Output Capacitors  
37 μV RMS Output Voltage Noise (10 Hz to 100  
kHz)  
•
•
Over-Temperature/Over-Current Protection  
±2% Output Voltage Tolerance  
This PMOS regulator is stable with small ceramic  
capacitive loads (2.2 μF typ).  
These devices also include regulation fault detection,  
a bandgap voltage reference, constant current limiting  
and thermal overload protection.
