MCZ33998EG - Brand New Freescale / NXP Linear Voltage Regulators
-
**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 low resistance LDMOS transistors.
There are two separate enable pins for the main and sensor supply outputs and standard supervisory functions such as resets with power-up reset delay. The 33998 provides proper power supply sequencing for advanced microprocessor architectures such as the MPC5xx and 683xx microprocessor families.Features
