Shenzhen Meiyuxin Technology Co., Ltd. 【Automotive Chip Supply】TPS7B8733QDDARQ1 Automotive 500mA, 40V Low Dropout (LDO) Voltage Regulator with Power Good Indication! ! !

Describe:

The TPS7B8733QDDARQ1 is a low-dropout linear regulator designed to connect to batteries in automotive applications. The device has an input voltage range of up to 40V, so it can withstand transients that can occur in automotive systems, such as load dumps. With only 17 µA of quiescent current at light loads, this device is an excellent solution for powering always-on devices such as microcontrollers (MCUs) and controller area network (CAN) transceivers in backup systems.

The TPS7B8733QDDARQ1 has an advanced transient response so that the output responds quickly to load or line changes (for example, during cold crank conditions). In addition, the device's novel architecture minimizes output overshoot during recovery from brownouts. In normal operation, the device maintains ±0.85% dc accuracy over line, load, and temperature. The power good delay can be adjusted by external components, so the delay time can be configured to suit an application-specific system.
