• Up to 2.2MHz switching frequency reduces external
component size and minimizes solution cost
• Available spread-spectrum and forced PWM features lower
EMI to minimize radio interference within the vehicle
• Current-controlled operation simplifies design effort and
enables cycle-by-cycle current limit
• 3A (MAX16961*) and 4A (MAX16962) output currents
support high-current requirements of processor cores
• Dual-channel MAX16963 saves additional board space
and offers most cost-effective solution

Ultra-Low-IQ Automotive LDO Conserves
Battery Life in Always-On Applications
45V, 200mA LDO Consumes Only 20μA IQ
The MAX16910 operates over a wide input-voltage
range (3.5V to 30V), survives load dumps up to
45V, and is guaranteed for operation over the
-40°C to +125°C automotive temperature range.
It includes three pin-selectable output-voltage
configurations: 5.0V or 3.3V fixed, and adjustable
from 1.5V to 11V. Additionally, the MAX16910
reduces component cost by operating with small
ceramic capacitors.
