The 33998 is a multiple output, medium power, integrated supply operating from a 6.0 to 26.5 V input source. A 5.0 V output is provided by a sensorless current mode step-down switching supply. A 2.6 V output is provided by a linear regulator using an external pass transistor. An additional 2.6 V output is provided for standby use along with two internally protected low RDS(on) LDMOS 5.0 V outputs for sensor use. Separate Enable inputs provide main and sensor supply output control with reset and power-on reset delay. The 33998 provides power supply sequencing for advanced microprocessor architectures such as the NXP® Semiconductors MPC5xx and 683xx microprocessor families.
