LP38852  
1.5A Fast-Response High-Accuracy Adjustable LDO Linear  
Regulator with Enable and Soft-Start  
General Description  
Features  
The LP38852-ADJ is a high current, fast response regulator  
which can maintain output voltage regulation with extremely  
low input to output voltage drop. Fabricated on a CMOS pro-  
cess, the device operates from two input voltages: VBIAS  
provides voltage to drive the gate of the N-MOS power tran-  
sistor, 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 ex-  
ternal capacitance is required to maintain loop stability.  
Adjustable VOUT range of 0.80V to 1.8V  
Wide VBIAS Supply operating range of 3.0V to 5.5V  
Stable with 10µF Ceramic capacitors  
Dropout voltage of 130 mV (typical) at 1.5A load current  
Precision Output Voltage across all line and load  
conditions:  
±1.5% VADJ for TJ = 25°C  
±2.0% VADJ for 0°C TJ +125°C  
±3.0% VADJ for -40°C TJ +125°C  
Over-Temperature and Over-Current protection  
Available in 8 lead PSOP, 7 lead TO-220 and 7 lead  
TO-263 packages  
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 part is avail-  
able in the TO-220 and TO-263 7-pin packages.  
−40°C to +125°C Operating Junction Temperature Range  
Applications  
Dropout Voltage: 130 mV (typical) at 1.5A load current.  
Low Ground Pin Current: 14 mA (typical) at 1.5A load cur-  
rent.  
ASIC Power Supplies In:  
- Desktops, Notebooks, and Graphics Cards, Servers  
- Gaming Set Top Boxes, Printers and Copiers  
Soft-Start: Programmable Soft-Start time.  
Server Core and I/O Supplies  
Precision ADJ Voltage: ±1.5% for TJ = 25°C, and ±2.0% for  
0°C TJ +125°C, across all line and load conditions  
DSP and FPGA Power Supplies  
SMPS Post-Regulator
