ADP1720ARMZ-5-R7

ADP1720 is a high voltage, micropower linear regulator. With just 28μA of quiescent supply current and a micropower shutdown mode, this device is ideal for applications that require low quiescent current. For automatic startup, the enable (EN) pin can be connected directly to the input rail. It is optimized for stable operation with small 1μF ceramic output capacitors, allowing for good transient performance while occupying minimal board space. This uses current limit protection and thermal overload protection circuits to prevent damage to the device in adverse conditions. It provides a compact solution with low thermal resistance. Application includes DC-to-DC post regulation, PCMCIA regulation, keep-alive power in portable equipment, industrial applications.
