The ADP1720 is a high-voltage, micro-power, low dropout
linear regulator. Designed for robust operation, the ADP1720
includes current limiting and short-circuit protection, and
thermal overload protection . With just 25µA of quiescent
supply current and a micro-power shutdown mode, this device
is ideal for applications that require low quiescent current. The
small thermally-enhanced MSOP package and 1µF ceramic
output capacitor provides a compact solution with low thermal
resistance for high power dissipation.
The ADP1720 is available in fixed output voltages of 3.3V and
5V, or its output voltage can be adjusted over a range of 1.2V to
5V. The ADP1720 operates over the -40°C to 125°C ambient
