Description

Create a design and simulate using EE-Sim^® tools:

The MAX16910 ultra-low quiescent current, high-voltage linear regulator is ideal for use in automotive and battery-operated systems. The device operates from a +3.5V to +30V input voltage, delivers up to 200mA of load current, and consumes only 20µA of quiescent current at no load. The device consumes only 1.6µA current when in shutdown. The input is +45V transient tolerant and is designed to operate under load-dump conditions. The MAX16910 can be configured as either fixed output voltage (+3.3V or +5V) or adjustable output voltage using an external resistive divider.

The MAX16910 features an open-drain, active-low RESET output with fixed thresholds offered at 92.5% and 87.5% of the output voltage. The active-low RESET output remains low for a fixed period of 60µs after the output voltage exceeds its threshold. The active-low RESET delay can be extended with an external capacitor.

The MAX16910 includes an enable input, short-circuit protection, and thermal shutdown. The MAX16910 operates over the -40°C to +125°C automotive temperature range. The device is available in a space-saving, thermally enhanced, 3mm x 3mm, 8-pin TDFN package and 5mm x 4mm, 8-pin SO package.
