Ultra-Low Output Voltage, Low-Quiescent-Current
Linear Regulator for High-Temperature Applications
General Description
The MAX16999 linear regulator operates from a 2.5V to
5.5V input voltage and delivers 100mA continuous load
current with a low quiescent current typically around
13μA. The output voltage is preset to internally trimmed
voltages in the 0.5V to 3.3V range (see the Selector
Guide). An active-low, open-drain reset output remains
low for a programmable timeout delay after the output
voltage reaches regulation. The reset timeout is pro-
grammed by an external capacitor connected to CRES.
This device also features logic-controlled shutdown,
and short-circuit and thermal-overload protection. The
typical applications are multimedia, telematics, and
motor control microcontrollers (μCs) with always-on
requirements. The MAX16999 is used as a parallel, low-
quiescent supply to power the core or interrupt section
of μCs during sleep mode. It can also be used to sup-
ply a timer or memory during μC shutoff. The adjustable
POR delay assists with power-supply sequencing.
