About MAX25210ATAD8

The MAX25210ATAD8 High voltage linear regulator is ideal for use in automotive and battery powered systems. Powered by +3.5V to +30V input voltages, the device provides up to 300mA of load current with a static current consumption of only 10µA (typical) when unloaded. The MAX25210ATAD8 has a current consumption of only 2µA (typical) when turned off. The input has a +42V transient tolerance to operate under sudden load drops. The MAX25210ATAD8 can be configured with a fixed output voltage (+3.3V or +5V) or with an adjustable output voltage using an external resistor divider.

In addition, the MAX25210ATAD8 has an open-leak, low-level active RESET output that provides 93.5% and 87.5% of the output voltage as fixed thresholds. After the output voltage exceeds its threshold, the low-level active RESET output will remain low for a fixed period of 60μs. Low level active RESET delay can be extended by external capacitors.

MAX25210ATAD8 includes enable input, short circuit protection, and thermal shutdown. The MAX25210ATAD8 operates in the automotive grade temperature range from -40°C to +125°C.
