The TPS7B4250-Q1 device is a monolithic, integrated low-dropout voltage tracker. The device is available in a SOT-23 package. The TPS7B4250-Q1 device is designed to supply off-board sensors in an automotive environment. The IC has integrated protection for overload, over temperature, reverse polarity, and output short-circuit to the battery and ground.
A reference voltage applied at the adjust-input pin, ADJ, regulates supply voltages up to VIN = 45 V with high accuracy and loads up to 50 mA.
By setting the adjust/enable input pin, ADJ/EN, to low, the TPS7B4250-Q1 device switches to standby mode which reduces the quiescent current to the minimum value.

NAME | NO. | ||
ADJ/EN | 1 | I | This pin connects to the reference voltage. A low signal disables the IC and a high signal enables the device. Connected the voltage reference directly or with a voltage divider for lower output voltages. To compensate for line influences, TI recommends to place a capacitor close to the IC pins. |
GND | 2 | G | Internally connected to pin 5 |
GND | 5 | G | Internally connected to pin 2 |
VIN | 3 | I | This pin is the device supply. To compensate for line influences, TI recommends to place a capacitor close to the IC pins. |
VOUT | 4 | O | VOUT is an external capacitor that is required between VOUT and GND with respect to the capacitance and ESR requirements given in the Recommended Operating Conditions. |
