GENERAL DESCRIPTION  
The ADP1720-EP is a high voltage, micropower, low dropout  
linear regulator. Operating over a very wide input voltage range  
of 4 V to 28 V, the ADP1720-EP can provide up to 50 mA of  
output current. With just 28 µA of quiescent supply current and a  
micropower shutdown mode, this device is ideal for applications  
that require low quiescent current.  
The ADP1720-EP is optimized for stable operation with small  
1 µF ceramic output capacitors, allowing for good transient  
performance while occupying minimal board space.  
The ADP1720-EP operates from –55°C to +125°C and uses  
current limit protection and thermal overload protection  
circuits to prevent damage to the device in adverse conditions.  
The ADP1720-EP is available in fixed output voltages of 3.3 V  
and 5.0 V. An adjustable version is also available, which allows  
the output to be set anywhere between 1.225 V and 5.0 V. An  
enable function that allows external circuits to turn on and turn  
off the ADP1720 output is available. For automatic startup, the  
enable (EN) pin can be connected directly to the input rail.  
Available in a small MSOP package, the ADP1720-EP provides  
a compact solution with low thermal resistance.  
Additional application and technical information can be found  
in the ADP1720 data sheet.
