PACKAGE DESCRIPTION
APPLICATIONS INFORMATION
Internal P-Channel Pass Transistor
The LTC1258 series features an internal P-channel MOSFET
pass transistor. This provides several advantages over
similar designs using a PNP bipolar pass transistor.
These references consume only 4μA of 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.
