Microchip announces MCP1790 and MCP1791 high-voltage linear regulators (LDOs). With a continuous
70 mA output, the ability to operate at a continuous input voltage of up to 30V and load-dump protection up to 43.5V, the new LDOs are ideal for automotive and industrial applications. They also feature low quiescent current, low shutdown current and ceramic capacitor stability, which enable smaller, ultra-efficient designs at lower costs.
The MCP179X LDOs were designed for use in applications requiring continuous operation at high input voltages, such as 12V automotive and 24V industrial applications. The built-in load-dump protection feature isolates the voltage transients often found in these types of applications, particularly those in the automotive market. All of this, combined with ceramic output capacitor stability and a low quiescent current of just
70 uA, enables more compact, power-efficient and reliable designs.
Example automotive applications include instrumentation lighting, power windows and locks, and stereo systems. High-voltage industrial applications include security systems, fire alarms, thermostat controls and sensors, among others.
Users can choose between the simple 3-pin MCP1790 LDO or the full-featured 5-pin MCP1791 LDO, which offers shutdown and power-good functionality. Both are available in thermally efficient SOT-223 and DDPAK packages. Samples of both LDOs are available at sample.microchip.com and volume quantities can be ordered at www.microchipdirect.com.
