High Performance 1A LDO

ISL78310

Features

The ISL78310 is a low dropout voltage, high-current, single

output LDO specified for 1A output current. This part operates

from input voltages down to 2.2V and up to 6V. The part offers

fixed and external resistor adjustable output voltages from 0.8V

to 5V. Custom voltage options are available upon request.

• 2.2V to 6V Input Supply

• 130mV Dropout Voltage Typical (at 1A)

• Fast Load Transient Response

• ±0.2% Initial V

OUT

Accuracy

• Adjustable In-Rush Current Limiting

• 58dB Typical PSRR

For applications that desire to set the in-rush current to less than

the current limit of the part, or for applications that require

turn-on time control, an external capacitor can be placed on the

soft-start pin for maximum control. A supply-independent

ENABLE signal allows the part to be placed into a low quiescent

current shutdown mode. Sub-micron CMOS process is used for

this product family to deliver best-in-class analog performance

and overall value.

• 63µV

Output Noise at V = 1.8V

OUT

RMS

• Power-Good Feature

• 500mV Feedback Voltage

• Supply-Independent 1V Enable Input Threshold

• Short-Circuit Current Protection

This CMOS LDO consumes significant lower quiescent (ground

pin) current as a function of load over bipolar LDOs, which

translates into higher efficiency and packages with smaller

footprints. Quiescent current is optimized to achieve a very fast

load transient response.

• 1A Peak Reverse Current

• Over-Temperature Shutdown

• Any Cap Stable with Minimum 10µF Ceramic

• ±1.8% Guaranteed V

OUT

Accuracy for Junction Temperature

The ISL78310 is both AEC-Q100 rated and fully TS16949

compliant. The ISL78310 is rated for the automotive

temperature range (-40°C to +125°C).

Range from -40°C to +125°C

• Available in a 10 Lead DFN Package

• Pb-Free (RoHS Compliant)

• AEC-Q100 Tested

Applications

• Core & I/O Power

• TS16949 Compliant

• Camera Modules

• Post Regulation of Switched Supplies

• Radio Systems

• Infotainment Systems
