Texas Instruments TPS7B88-Q1 LDO Linear Regulators

Texas Instruments TPS7B88-Q1 LDO Linear Regulators provide an input voltage range extending to 40V, which allows the device to withstand transients (such as load dump) expected in automotive systems. The TPS7B88-Q1 Regulators utilize only a 17µA quiescent current at light loads, making it ideal for powering always-on components such as microcontrollers (MCUs) and controller area network (CAN) transceivers in standby systems.

The TI TPS7B88-Q1 LDO Linear Regulators feature a state-of-the-art transient response that allows the output to react to changes in load or line (for example, during cold-crank conditions) quickly. Additionally, the device has a novel architecture that minimizes output overshoot when recovering from a dropout. The TPS7B88-Q1 has a tight DC accuracy of ±1.15% over line, load, and temperature, during normal operation.

The TPS7B88-Q1 Regulators are available in thermally conductive packaging to allow the parts to transfer heat to the circuit board efficiently.
