Linear regulator consumes 13-microamps quiescent current

Sunnyvale, Calif.—Maxim Integrated Products has introduced the MAX16999, a low-output-voltage linear regulator capable of delivering up to 100mA for always-on applications.

Designed as a parallel supply for powering the core or interrupt section of a microcontroller during sleep mode, this device consumes 13µA of quiescent current. To further reduce power consumption, it provides an enable input for placing the regulator in shutdown, in which it consumes 0.3µA. Available in 13 factory-preset output voltages ranging from 0.5V to 3.3V, the MAX16999 eliminates the need for external feedback resistors.

This device is aimed at always-on automotive and industrial applications that require high reliability and low power consumption.

Designed for harsh operating environments, the MAX16999 features overcurrent and overtemperature protection, as well as power-on-reset circuitry with adjustable timing. The device is fully specified over the -40°C to +125°C automotive temperature range, and is available in a thermally enhanced, 8-pin microMAX package.

Pricing: Starts at $0.70 (1000-up, FOB USA).
Availability: Now.
