Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix MR-G confirms the SOT-25 package configuration and RoHS compliance status before procurement. Ensure that the external resistor values selected for the C-series variant account for the internal feedback resistance variation to maintain the specified voltage accuracy. Confirm availability through authorized distributors as supply may be restricted.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when an adjustable output voltage up to 23 V is required within a 28 V input system. The C-series designation indicates external voltage setting capability, distinct from fixed-output B or D series variants. Consider the SOT-25 package constraints regarding power dissipation and thermal management for the intended application environment.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the IXD1216 family of low-dropout regulators produced by Zilog. The C-series specifically denotes devices where the output voltage is programmable via an external feedback network rather than being factory-trimmed to a fixed value. The MR-G suffix identifies the SOT-25 surface-mount package with lead-free and halogen-free compliance.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

How is the output voltage determined for the IXD1216C series?

The output voltage is set externally using a resistive divider connected to the FB pin, allowing adjustment from 2.0 V to 23.0 V.

What is the function of the CE pin on the IXD1216C?

The Chip Enable (CE) pin controls the active and standby modes; a high level activates the regulator, while a low level reduces current consumption to less than 0.1 µA.
