The ISL88706IB831Z-TK is a current-limited low dropout (LDO) linear voltage regulator designed for automotive applications. It is ideal for system voltage regulation in applications such as automotive diagnostics, display driver, MCU, audio amplifier, sensors, and 5V power rail management. The ISL88706IB831Z-TK is designed to ensure reliable operation in harsh automotive environments, with a temperature range from -40°C to +125°C.

The ISL88706IB831Z-TK is a robust, low-noise power monitoring and supervising IC. It provides user-selectable, digitally-controlled output voltages and a wide input-voltage range. It regulates the system power to within ±5% of the nominal setting, maintaining the output voltage steady in the face of varying input and load conditions. The device has an adjustable overvoltage protection (OVP) of up to 6.3V, to guard against an accidental overvoltage condition on the output rail. It also features loss of power monitoring and a delayed retry on power-up, as well as loss of ground monitoring.

The ISL88706IB831Z-TK has a 2.5V to 5.75V input voltage range, adjustable output voltage from 1.1V to 5.1V. It also has two separate power planes that provide the system with two distinct power supplies, such as digital and analog power in a system. The device is also highly efficient and provides up to 1A of output current with a quiescent current as low as 5μA.

The ISL88706IB831Z-TK also offers additional features such as an adjustable soft-start ramp time, adjustable output overvoltage protection, adjustable delay time on power-up, adjustability of loss of ground (LOGIC) assertion timeout window, adjustable reset pulse width, and adjustable window-WATCHDOG timeout. The device also has low power-consumption modes and an active-low toggle Power-Good output (PGOOD) signal.

The ISL88706IB831Z-TK is the ideal supervisor for system voltage regulation in automotive applications. Its advanced features offer improved performance and reliability subject to the most severe environmental conditions. With its combination of accurate voltage regulation and current-limiting and protection features, it is well-suited for use in harsh automotive and industrial applications.
