Regulator consumes 13?A, suits always-on automotive apps

Maxim Integrated Products has developed 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 MCU during sleep mode, the MAX16999 consumes a mere 13?A of quiescent current. To further reduce power consumption, it provides an enable input for placing the regulator in shutdown, in which it consumes only 0.3?A.

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 suitable for 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 -40C to +125C automotive temperature range, and is available in a thermally enhanced, 8-pin ?MAX package. Prices start at $0.70 (1,000-up, FOB USA).
