LT1185MK

The LT1185MK is one member of the LT1185 family which is designed as the saturation-limited NPN transistor that has all the protection features of previous LTC regulators, including power limiting and thermal shutdown. This device uses a saturation-limited NPN transistor as the pass element and gives the linear dropout characteristics of an FET pass element with significantly less die area.

Features of the LT1185MK are:(1)low resistance pass transistor: 0.25W; (2)dropout voltage: 0.75V at 3A; (3)+/- 1% reference voltage; (4)accurate progra-mmable current limit; (5)shutdown capability; (6)internal reference available; (7)standard 5-lead packages; (8)full remote sense; (9)low quiescent current: =2.5mA; (10)good high frequency ripple rejection.

The absolute maximum ratings of the LT1185MK can be summarized as:(1)input voltage:35 V;(2)input-output differential:30 V;(3)FB voltage:7 V;(4)REF voltage:7 V;(5)output voltage:30 V;(6)output reverse voltage:2 V;(7)operating ambient temperature range:-55°C to 125°C;(8)operating junction temperature range:-55°C to 150°C;(9)power transistor section:-55°C to 175°C;(10)storage temperature range:-65°C to 150°C;(11)lead temperature (soldering, 10 sec):300°C.
