ADP1720ARMZ-R7

ADP1720 is a high voltage, micropower, low dropout linear regulator. Operating over a very wide input voltage range of 4V to 28V, this can provide up to 50mA of output current. 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. This is optimized for stable operation with small 1μF ceramic output capacitors, allowing for good transient performance while occupying minimal board space. Application includes DC-to-DC post regulation, PCMCIA regulation, keep-alive power in portable equipment, industrial applications.
