The ADPL44001 ultra-low quiescent current, highvoltage linear regulator is ideal for use in industrial and battery-operated systems. The device operates from a 4V to 40V 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 38V voltage range. Feedback voltage accuracy is ±2% over temperature.

An open-drain PGOOD pin provides a power-good signal to the system, 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 ADPL44001 operates over the -40°C to +125°C industrial temperature range and is available in a 6-lead, compact TSOT and a 6-pin (3mm x 3mm) TDFN packages.

Product Details

The ADPL44001 evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the performance of the ADPL44001 high-voltage, ultra-low quiescent current linear regulator. The EV kit operates over a wide input voltage range of 4V to 40V and provides up to 100mA load current. It draws only 8μA supply current under no-load conditions. The device is simple to use and easily configurable with minimal external components. It features overload current protection and thermal shutdown.

The EV kit consists of two circuits: one circuit is installed with the ADPL44001AZT+ in a 6-pin, compact TSOT package. The second circuit is installed with the ADPL44001ATT+ in a 6-pin (3mm x 3mm) TDFN package.
