ISL6416 is a triple output low-noise LDO regulator with an integrated microprocessor reset circuit and is optimized for powering wireless chipsets. 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 30µVRMS (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.
The ISL6416 is an ultra‑low‑noise triple‑output LDO regulator with an integrated microprocessor reset circuit, optimized for powering wireless chip sets. It accepts a 3.0 V to 3.6 V input and provides three regulated outputs: 1.8 V (LDO1) and two 2.8 V outputs (LDO2 and LDO3), with LDO3 delivering noise below 30 µVRMS to support VCO stability.
The device includes extensive protection features such as over‑current, short‑circuit, and thermal shutdown, and offers a programmable reset delay. It is offered in a 16‑lead SSOP package and is RoHS‑compliant, with tape‑and‑reel packaging available.
