... LTC1258-2.5, yet the same connection can deliver 10mA of load current when demanded. Output Bypass Capacitor The LTC1258 series is designed to be stable with or without capacitive loads. With no capacitive load, the reference is ideal for fast settling applications, or where PC board space premium. ...

... These references consume only quiescent current under light and heavy loads as well as in dropout; whereas, PNP-based references waste considerable amounts of current when the pass transistor is saturated. In addition, the LTC1258 series provides a lower dropout voltage (200mV max) than PNP-based references. U Dimenshions in inches (millimeters) unless otherwise noted. ...
