ADP1720TRMZ3.3EPR7

ADP1720TRMZ3.3EPR7 is a 50mA, high voltage, micropower linear regulator. Operating over a very wide input voltage range of 4V to 28V, the ADP1720-EP can provide up to 50mA 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 1µF 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. Applications include DC-to-DC post regulation, PCMCIA regulation, keep-alive power in portable equipment, Industrial applications, aeronautic and military operating temperature environment.
