AEK-POW-LDOV02X

AEK-POW-LDOV02X is a dual linear voltage regulator evaluation board with configurable output voltage and diagnostic features based on automotive-grade L99VR02XP. The L99VR02XP operates with reduced input voltage, minimizing internal power dissipation and maximizing output current. Output current limitation protects regulator and application from overload conditions, such as short to ground. Thanks to its operating temperature range (Tj=-40 to 175°C), the device is suitable for electronic applications with high temperature environments and for applications that require stable power supplies (for eg, navigation systems, MCU supplies, audio systems, automotive display drivers, sensors, infotainment processors and powertrain systems). In automotive systems, thermal performance is always a critical concern for battery-direct-connection LDOs. The LDO connected to car battery needs to convert battery voltage down to 5, 3.3V, or even lower voltage for powering MCU, CAN bus, and other devices.

• L99VR02XP dual automotive-grade linear voltage regulator
