MCP1722-3310H/Q8BVAO

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

The MCP1722-3310H/Q8BVAO is a high-voltage dual-output low dropout (LDO) linear voltage regulator manufactured by Microchip Technology. It provides two fixed output voltages: 3.3V at 100mA and 10V at 50mA. The device operates with an input voltage range up to 16V, ensuring stable regulation under varying load conditions. It features low quiescent current consumption and is housed in an 8-pin VDFN package with an exposed pad for enhanced thermal performance.

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

Verify the exact suffix 'VAO' corresponds to the specific tube packaging and RoHS compliance status as defined by Microchip. Confirm the operating temperature range matches your application environment. Ensure the 8-VDFN footprint aligns with your PCB layout guidelines. Cross-reference the datasheet revision date to ensure compatibility with latest electrical specifications.

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

Select this component when a single IC must provide both a standard logic voltage and a higher auxiliary voltage. The 100mA output suits moderate load currents, while the 50mA rail supports lower-power peripherals. Consider the thermal dissipation capabilities of the VDFN package relative to ambient temperature constraints. Verify that the input voltage does not exceed the maximum rating during transient events.

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

This part belongs to the MCP1722 family of dual-output LDO regulators. Variants within the family offer different output combinations, such as 3.3V/5V or 3.3V/12V. The '3310' designation specifically indicates the 3.3V and 10V output configuration. The 'Q8B' denotes the commercial temperature grade and package type. This series is designed for cost-sensitive applications requiring multiple regulated supplies from a single source.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes include other MCP1722 variants with matching output voltages, such as MCP1722-3312H/Q8BVAO for 3.3V/12V outputs. Ensure any replacement maintains the same pinout and thermal characteristics. Verify that alternative components meet the same input voltage and current capability requirements.
