LP38853

3A Fast-Response High-Accuracy Adjustable LDO Linear

Regulator with Enable and Soft-Start

General Description

Features

The LP38853-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: V_BIAS

provides voltage to drive the gate of the N-MOS power tran-

sistor, while V_INis the input voltage which supplies power to

the load. The use of an external bias rail allows the part to

operate from ultra low V_INvoltages. 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 V_OUTrange of 0.80V to 1.8V

■

Wide V_BIASSupply operating range of 3.0V to 5.5V

Stable with 10µF Ceramic capacitors

Dropout voltage of 240 mV (typical) at 3A load current

Precision V_ADJacross all line and load conditions:

■

±1.5% V_ADJfor T_J= 25°C

—

±2.0% V_ADJfor 0°C ≤ T_J≤ +125°C

±3.0% V_ADJfor -40°C ≤ T_J≤ +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 PSOP 8–pin, TO-220 7–pin, and TO-263 7-pin pack-

ages.

−40°C to +125°C Operating Junction Temperature Range

■

Applications

ASIC Power Supplies in:

- Desktops, Notebooks, and Graphics Cards, Servers

- Gaming Set Top Boxes, Printers and Copiers

■

Dropout Voltage: 240 mV (typical) at 3A load current.

Low Ground Pin Current: 10 mA (typical) at 3A load current.

Soft-Start: Programmable Soft-Start time.

Precision ADJ Voltage: ±1.5% for T_J= 25°C, and ±2.0% for

0°C ≤ T_J≤ +125°C, across all line and load conditions
