ISL80410
40V, Low Quiescent Current, 150mA Linear Regulator
FN8983
Rev. 0.00
Jan 24, 2018
The
ISL80410
is a high voltage, adjustable V
OUT
, low
quiescent current linear regulator ideally suited for
“always-on” and “keep alive” applications. The
ISL80410 operates from an input voltage of +6V to
+40V under normal operating conditions and consumes
only 18µA of quiescent current at no load.
The ISL80410 features an EN pin that can be used to put
the device into a low-quiescent current shutdown mode
in which it draws only 2µA of supply current. The device
features over-temperature shutdown and current limit
protection.
The ISL80410 is rated to operate across the -40°C to
+125°C temperature range and is available in an 8 Ld
Small Outline Exposed Pad Plastic Package (EPSOIC).
Features
• Wide V
IN
range of 6V to 40V
• Adjustable output voltage from 2.5V to 12V
• Guaranteed 150mA output current
• Ultra low 18µA typical quiescent current
• Low 2µA of typical shutdown current
• ±1% accurate voltage reference
• Low dropout voltage of 295mV at 150mA
• 40V tolerant logic level (TTL/CMOS) enable input
• Stable operation with 10µF output capacitor
• 5kV ESD HBM rated
• Thermal shutdown and current limit protection
• 8 Ld exposed pad EPSOIC package
Applications
• Industrial
• Telecommunications

Notes:
1. Add “-T” suffix for 2.5k unit and “-T7A” suffix for 250 unit tape and reel options. Refer to
TB347
for details about reel
specifications.
2. These Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and
100% matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free
soldering operations). Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), refer to the
ISL80410
product information page. For more information about MSL, refer to
TB363.

Description
Input voltage pin. A minimum 0.1µF X5R/X7R capacitor is required for proper operation.
Range: 6V to 40V
These pins have internal termination and can be left unconnected. Connection to ground is optional.
Set this pin high to enable the device. Range: 0V to V
IN
Ground pin.
This pin is connected to the external feedback resistor divider, which sets the LDO output voltage.
Regulated output voltage. A 10µF X5R/X7R output capacitor is required for stability. Range: 0V to 12V
It is recommended to solder the PAD to the ground plane.

Notes:
6. Dropout voltage is defined as (V
IN
- V
OUT
) when V
OUT
is 2% below the value of V
OUT
.
7. Enable to Regulation is the time the output takes to reach 95% of its final value with V
IN
= 14V. EN is taken from V
IL
to V
IH
in 5ns.
For the adjustable versions, the output voltage is set at 5V.
8. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by
characterization and are not production tested.
