to 1.2 V with the nominal default setting as 1.1 V. The LDO_1P1 supplies the 24 MHz oscillator, PLLs,

and USB PHY. A programmable brown-out detector is included in the regulator that can be used by the

system to determine when the load capability of the regulator is being exceeded to take the necessary steps.

Current-limiting can be enabled to allow for in-rush current requirements during start-up, if needed.

Active-pull-down can also be enabled for systems requiring this feature.

For information on external capacitor requirements for this regulator, see the Hardware Development

Guide for i.MX 6Quad, 6Dual, 6DualLite, 6Solo Families of Applications Processors

(IMX6DQ6SDLHDG).

For additional information, see the i.MX 6DualPlus/6QuadPlus reference manual (IMX6DQPRM).

LDO_2P5 / VDDHIGH_CAP

The LDO_2P5 module implements a programmable linear-regulator function from VDD_HIGH_IN (see

Table 6 for min and max input requirements). Typical Programming Operating Range is 2.25 V to 2.75 V

with the nominal default setting as 2.5 V. The LDO_2P5 supplies the eFuses, PLLs, and USB PHY.

Optionally it can be used to supply the HDMI, LVDS, MIPI, PCIe, and SATA PHY's through external

connections. A programmable brown-out detector is included in the regulator that can be used by the

system to determine when the load capability of the regulator is being exceeded, to take the necessary

steps. Current-limiting can be enabled to allow for in-rush current requirements during start-up, if needed.

Active-pull-down can also be enabled for systems requiring this feature. An alternate self-biased

low-precision weak-regulator is included that can be enabled for applications needing to keep the output

voltage alive during low-power modes where the main regulator driver and its associated global bandgap

reference module are disabled. The output of the weak-regulator is not programmable and is a function of

the input supply as well as the load current. Typically, with a 3 V input supply the weak-regulator output

is 2.525 V and its output impedance is approximately 40

Ω.

Guide for i.MX 6Quad, 6Dual, 6DualLite, 6Solo Families of Applications Processors

4.3.2.3

LDO_USB / VDD_VBUS_CAP

The LDO_USB module implements a programmable linear-regulator function from the

USB_OTG_VBUS and USB_H1_VBUS voltages (4.4 V–5.25 V) to produce a nominal 3.0 V output

voltage. A programmable brown-out detector is included in the regulator that can be used by the system to

determine when the load capability of the regulator is being exceeded, to take the necessary steps. This

regulator has a built in power-mux that allows the user to select to run the regulator from either VBUS

supply, when both are present. If only one of the VBUS voltages is present, then the regulator

automatically selects this supply. Current limit is also included to help the system meet in-rush current

targets. If no VBUS voltage is present, then the VBUSVALID threshold setting will prevent the regulator

from being enabled.
