ISL6416
Triple Output, Low-Noise LDO Regulator
with Integrated Reset Circuit
The ISL6416 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
exceed 30μV
RMS
(typical) to aid VCO stability. High
integration makes the ISL6416 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 ISL6416 uses an internal PMOS transistor as the pass
device. The ISL6416 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. FAULT indicates the loss of
regulation on LDO1.
