EVALUATION KIT AVAILABLE MAX16910 200mA, Automotive, Ultra-Low Quiescent Current, Linear Regulator General Description Benefits and Features The MAX16910 ultra-low quiescent current, high-voltage Enables System Designers to Meet Stringent Module linear regulator is ideal for use in automotive and battery- Requirements for 100A Quiescent Current operated systems. The device operates from a +3.5V Low 20A Quiescent Current to +30V input voltage, delivers up to 200mA of load Up to 200mA Output-Current Capability current, and consumes only 20A of quiescent current at User-Selectable Output Voltage (+3.3V or +5V no load. The device consumes only 1.6A current when Fixed and +1.5V to +11V Adjustable with in shutdown. The input is +45V transient tolerant and is External Resistive Divider) designed to operate under load-dump conditions. The Tiny Output Capacitors Reduce Board Space and MAX16910 can be configured as either fixed output volt- BOM Cost age (+3.3V or +5V) or adjustable output voltage using an Stable Operation with 4.7F Output Capacitor external resistive divider. Accurate RESET Output with Adjustable Delay The MAX16910 features an open-drain, active-low RESET Eliminates Need for Separate Reset IC output with fixed thresholds offered at 92.5% and 87.5% Open-Drain RESET Output with Adjustable Delay of the output voltage. The RESET output remains low for Fixed-Reset Threshold Options: 87.5% or 92.5% a fixed period of 60s after the output voltage exceeds Operates Through Cold-Crank Conditions its threshold. The RESET delay can be extended with an Low-Dropout Voltage of 280mV at 200mA external capacitor. +3.5V to +30V Wide Input Voltage Range, The MAX16910 includes an enable input, short- +45V Tolerant circuit protection, and thermal shutdown. The MAX16910 Robust Performance in Automotive Environment operates over the -40C to +125C automotive tempera- Thermal and Short-Circuit Protection ture range. The device is available in a space-saving, High-Voltage Enable Input (+45V) thermally enhanced, 3mm x 3mm, 8-pin TDFN package Operating -40C to +125C Temperature Range and 5mm x 4mm, 8-pin SO package.
