Data sheet:
The AEK-POW-LDOV02X is an evaluation board based on the L99VR02XP dual automotive-grade linear voltage regulator.
The L99VR02XP operates with reduced input voltage, minimizing the internal power dissipation and maximizing the output current.
Output current limitation protects the regulator and the application from overload conditions, such as short to ground.
Thanks to its operating temperature range (Tj=-40°C to 175°C), the device is suitable
for electronic applications with high temperature environments and for applications that require stable power supplies (for example, navigation systems, microcontroller 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 a car battery needs to convert the battery voltage down to 5, 3.3 V, or even lower voltage for powering MCU, CAN bus, and other devices. In these situations, the voltage drop on the LDO might be very high and power dissipation on the LDO might even exceed 1 W for a 100-mA loading current. If the system demands several hundred milliamps of current, a single LDO cannot handle the power dissipation.
Our AEK-POW-LDOV02X evaluation board addresses this challenge, thanks to the L99VR02XP dual linear voltage regulator, reaching a higher output current and distributing power consumption among multiple devices.
LDO2 automatic voltage tracking and de-tracking of LDO1 or of an external LDO voltage represents an accurate solution for automotive off-board sensors and small current off-board modules, where the power supply runs through a long cable from the main board.
Under this condition, the long cable might be damaged, causing short-to-ground, short-to-battery or other fault events. In these cases, the system needs to implement a mechanism to protect on-board components from being damaged. Meanwhile, it is necessary to keep the voltage-tracking tolerance between the off-board sensors power supply and the MCU/ADC power supply to the lowest level. In this scenario, the voltage-tracking LDO represents the perfect solution for driving the off-board loads, offering full protection features and ultra-accurate output tracking voltage.
