Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for CMPWR025R

CMPWR025R

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

The CMPWR025R is a dual input SmartOR power switch manufactured by California Micro Devices. It implements logical OR selection between two inputs (VCC1 and VCC2) to provide a single output. The device features integrated low impedance switches with typical resistance of 0.2 Ω. Operating supply range is 2.8V to 5.5V, providing up to 600mA output current. It ensures glitch-free output during supply switching transitions and has a low operating supply current of 20µA. User-selectable hysteresis prevents switch chatter.

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

Verify the manufacturer origin, as the datasheet identifies California Micro Devices Corp. while the prompt specifies onsemi. Confirm the package type is 8-pin MSOP and check RoHS compliance status. Ensure the ordering suffix 'R' corresponds to tape and reel shipping format as indicated in the documentation.

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

Select this component for applications requiring seamless power source redundancy with minimal voltage drop. Consider the user-selectable hysteresis feature for noisy environments. Evaluate thermal dissipation constraints given the 0.3W power rating in the MSOP package. Verify that the required load current does not exceed the 600mA standard operating limit.

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

The CMPWR025R belongs to the SmartOR family of dual input power switches. It serves as an improved solution over simple diode ORing by reducing losses significantly compared to Schottky diodes. Designed to operate above the 1W sleep mode rating specified in PCI Rev 2.2, it supports Instantly Available Personal Computer (IAPC) applications.
