ISL6412
Triple Output, Low-Noise LDO Regulator
with Integrated Reset Circuit
The ISL6412 is an ultra low noise triple output LDO regulator
with microprocessor reset circuit and is optimized for
powering wireless chip sets. The IC accepts an input voltage
range of 3.0V to 3.6V and provides three regulated output
voltages: 1.8V (LDO1), 2.8V (LDO2), and another ultra-
clean 2.8V (LDO3). On chip logic provides sequencing
between LDO1 and LDO2 for the BBP/MAC and the I/O
supply voltage outputs. LDO3 features ultra low noise that
does not typically exceed 30V RMS to aid VCO stability.
High integration and the thin Quad Flat No-lead (QFN)
package makes the ISL6412 an ideal choice to power many
of today’s small form factor industry standard wireless cards
such as PCMCIA, mini-PCI and Cardbus-32.
The ISL6412 uses an internal PMOS transistor as the pass
device. The ISL6412 also integrates a reset function, which
eliminates the need for the additional reset IC required in
WLAN applications. The IC asserts a RESET signal
whenever the VIN supply voltage drops below a preset
threshold, keeping it asserted for at least 25ms after Vin has
risen above the reset threshold. FAULT1 indicates the loss
of regulation on LDO1.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
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.
