Overview

The MCP1722-5012H/S7X is a high-voltage dual-output LDO regulator capable of handling input voltages up to 55V. It provides two fixed voltage outputs, 12V and 5V, with current capabilities of 50mA and 100mA respectively. This device is specifically designed for applications requiring high-voltage startup bias or multi-rail power in space-constrained designs.

Why Choose This Part

The device integrates two regulators into a single SOIC-8 package, significantly reducing PCB footprint for dual-rail systems. It features a high 55V maximum input rating and an extended operating temperature range up to 150 degrees Celsius, making it suitable for thermally demanding environments.

Applications

Battery Powered Tools
Provides regulated logic and gate drive rails directly from high-voltage battery packs.
PWM Controller Startup Bias
Acts as a high-input voltage bias supply for switch-mode power supply controllers.
Handheld Vacuums
Manages dual-rail requirements for control logic and sensors in cordless appliances.

Getting Started

When designing with this LDO, ensure adequate thermal dissipation through the SOIC-8 leads as the 55V input capability can lead to high power dissipation at maximum load. Utilize the Enable and Power Good pins for sequenced power-up or system health monitoring. Review the datasheet for recommended input and output capacitor ESR values to maintain stability across the extended temperature range.
