LP38859 3-A Fast-Response High-Accuracy LDO Linear Regulator With Soft Start  
1 Features  
3 Description  
The LP38859 is  
a
high-current, fast-response  
1
•
Input Voltage: 1.1 V to 5.5 V  
regulator which can maintain output voltage  
regulation with extremely low input to output voltage  
drop. Fabricated on a CMOS process, the device  
operates from two input voltages: VBIAS provides  
voltage to drive the gate of the N-MOS power  
transistor, while VIN is the input voltage which  
supplies power to the load. The use of an external  
bias rail allows the part to operate from ultra-low VIN  
voltages. Unlike bipolar regulators, the CMOS  
architecture consumes extremely low quiescent  
current at any output load current. The use of an N-  
MOS power transistor results in wide bandwidth, yet  
minimum external capacitance is required to maintain  
loop stability.

Overtemperature and Overcurrent Protection  
The fast transient response of this device makes it  
suitable for use in powering DSP microcontroller core  
voltages and switch-mode power-supply post-  
regulators. The LP38859 is available in 5-pin TO-220  
and DDPAK/TO-263 packages.  
Operating Temperature Range: −40°C to +125°C
