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

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
