... The trade-off for this im- proved performance maximum supply voltage. Similar to the LT1083/LT1084/LT1085 family, the LT1585- 1.5/LT1585A-1.5 regulators require an output capacitor for stability. However, the improved frequency compensation permits the use of capacitors with much lower ESR while still maintaining stability ...

... A possible stability problem that occurs in monolithic linear regulators is current limit oscillations. The LT1585-1.5/ LT1585A-1.5 essentially have a flat current limit over the W U range of input supply voltage. The lower current limit rating and 7V maximum supply voltage rating for this device permit this characteristic ...
