MAX25210 Automotive Ultra Low Quiescent Current Linear Regulator Family General Description Benefits and Features The MAX25210 high-voltage linear regulator family is ideal Enables System Designers to Meet Stringent Module for use in automotive and battery-operated systems. The Requirements for 100A Quiescent Current device operates from a +3.5V to +36V input voltage, deliv- Low 10A Quiescent Current ers up to 300mA of load current, and consumes only 10A 300mA Output-Current Capability (300mA, 200mA, of typical quiescent current at no load. The device con- 100mA, and 50mA Variants) sumes only 2A (typ) current when in shutdown. The input User-Selectable Output Voltage (+3.3V or +5V is +42V transient tolerant and is designed to operate under Fixed and +0.6V to +11V Adjustable with External load-dump conditions. The MAX25210 can be configured Resistive Divider) as either fixed output voltage (+3.3V or +5V) or adjustable Tiny Output Capacitors Reduce Board Space and output voltage using an external resistive divider. BOM Cost The MAX25210 features an open-drain, active-low RE- Stable Operation with 2.2F Output Capacitor SET output with fixed thresholds offered at 93.5% and Accurate RESET Output with Adjustable Delay 87.5% of the output voltage. The RESET output remains Eliminates Need for Separate Reset IC low for a fixed period of 60s after the output voltage ex- Open-Drain RESET Output with Adjustable Delay ceeds its threshold. The RESET delay can be extended Fixed-Reset Threshold Options: 87.5% or 93.5% with an external capacitor. Operates Through Cold-Crank Conditions The MAX25210 includes an enable input, short-circuit pro- Low-Dropout Voltage of 280mV at 200mA tection, and thermal shutdown. The MAX25210 operates +3.5V to +36V Wide Input Voltage Range, +42V over the -40C to +125C automotive temperature range. Tolerant The regulators are available in a space-saving, thermally Robust Performance in Automotive Environment enhanced, 3mm x 3mm, 8-pin TDFN package.
