MAX17651
60V, 100mA, Ultra-Low Quiescent Current,
Linear Regulator
General Description
The MAX17651 ultra-low quiescent current, high-voltage
linear regulator is ideal for use in industrial and battery-
operated systems. The device operates from a 4V to 60V
input voltage, delivers up to 100mA of load current, and
consumes only 8μA of quiescent current at no load. The
device consumes only 0.9μA current when in shutdown.
Output voltage is adjustable in the 0.6V to 59V voltage
range. Feedback voltage accuracy is ±2% over temperature.
An open-drain, active-low PGOOD pin provides a power-
good signal to the system upon achieving successful
regulation of the output voltage. The device also incorporates
an enable pin (EN) that allows the user to turn the part
on or off. The device has a thermal shutdown feature that
shuts down the part when the die temperature exceeds
165°C. The MAX17651 operates over the -40°C to
+125°C industrial temperature range and is available in a
6 lead, compact TSOT package.
