Overview
...gulators The 33998 is a medium-power, multi-output power supply integrated circuit that is capable of operating over a wide input voltage range, from 6.
0 V up to 26.
5 V with 40 V transient capability.
It incorporates a sensorless current mode control step-down switching controller regulating directly to 5.
0 V.
The 2.
6 V linear regulator uses an external pass transistor to reduce the 33998 power dissipation.
The 33998 also provides a 2.
6 V linear standby regulator and two 5.
0 V sensor supply outputs protected by internal lowresistance LDMOS transistors.
There are two separate enable pins for the main and sensor supply outputs and standard supervisory functions such as resets with www.
