High Performance 2A and 3A Linear Regulators
ISL80102, ISL80103
Features
• Stable with all Capacitor Types (Note 11)
• 2A and 3A Output Current Ratings
• 2.2V to 6V Input Voltage Range
The ISL80102 and ISL80103 are low voltage,
high-current, single output LDOs specified for 2A and 3A
output current, respectively. These LDOs operate from
input voltages of 2.2V to 6V and are capable of providing
output voltages of 0.8V to 5V on the adjustable V
• ±1.8% V

versions. Fixed output voltage options are available in
1.5V, 1.8V, 2.5V, 3.3V and 5V. Other custom voltage
options available upon request.

Versions
For applications that demand in-rush current less than
the current limit, an external capacitor on the soft start
pin provides adjustment. The ENABLE feature allows the
part to be placed into a low quiescent current shutdown
mode. A sub-micron BiCMOS process is utilized for this
product family to deliver the best in class analog
performance and overall value.
• Very Fast Transient Response
• Excellent 62dB PSRR
• 100µV

Output Noise
• Power-Good Output
• Adjustable In-Rush Current Limiting
• Short Circuit and Over-Temperature Protection
These CMOS LDOs will consume significantly lower
quiescent current as a function of load over bipolar LDOs,
which translates into higher efficiency and the ability to
consider packages with smaller footprints. Quiescent
current is modestly compromised to enable a leading
class fast load transient response, and hence a lower
total AC regulation band for an LDO in this category.
• Available in a 10 Ld DFN (now), 5Ld TO220 and 5Ld
TO263 (soon)
