The ADP1720ARMZ-3.3-R7 is a high voltage, micropower, low dropout linear regulator. Operating over a very wide input voltage range of 4 V to 28 V, the ADP1720ARMZ-3.3-R7 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 ADP1720ARMZ-3.3-R7 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 ADP1720ARMZ-3.3-R7 output is available. For automatic startup, the enable (EN) pin can be connected directly to the input rail.
The ADP1720ARMZ-3.3-R7 is optimized for stable operation with small 1 μF ceramic output capacitors, allowing for good transient performance while occupying minimal board space.
The ADP1720ARMZ-3.3-R7 operates from –40°C to +125°C and uses current limit protection and thermal overload protection circuits to prevent damage to the device in adverse conditions.
Available in a small thermally enhanced MSOP package, the ADP1720ARMZ-3.3-R7 provides a compact solution with low thermal resistance.
