Introduction

MAC7200 Microcontroller Family Reference Manual, Rev. 2

406

Freescale Semiconductor

The regulator is active, providing the nominal supply voltage of 1.5V/3.3V with full current

sourcing capability at all outputs. Features LVR (Low Voltage Reset) and POR (Power-On Reset)

are available.

•

Shutdown Mode

Controlled by VREGEN (see MCU level specification for connectivity of VREGEN).

This mode is characterized by minimum power consumption. The regulator outputs are in a high

impedance state, only the POR feature is available, LVR is disabled.

This mode must be used to disable the chip internal regulator VREG_HIP7A, i.e. to bypass the

VREG_HIP7A to use external supplies.

Block Diagram

Figure 22-1 shows the function principle of VREG_HIP7A by means of a block diagram. The regulator

core REG consists of two parallel subblocks, REG1 and REG2, providing two independent output

voltages.
