3 Description
The TPS7B4255-Q1 is a low-dropout (LDO) voltagetracking
regulator, with high tracking accuracy and
excellent load and line transient response. The device
is available in two 5-pin, SOT-23 packages (DBV
and DYB). The TPS7B4255-Q1 is designed to supply
off-board sensors in automotive applications such as
powertrain systems. The device provides integrated
protection features such as reverse polarity, output
short to battery and ground, and current limit and
thermal shutdown to protect against the high risk
of cable failures in an off-board power system. The
device is designed to maintain a 45-V (absolute
maximum) input voltage to sustain the load dump
transient conditions.
A reference voltage applied at the ADJ/EN pin
effectively buffers the voltage with high accuracy
for loads up to 70 mA. The high tracking
accuracy provides accurate power supply to the offboard
modules and enables better accuracy when
measuring ratiometric sensors.
By setting the ADJ/EN input pin low, the TPS7B4255-
Q1 switches to standby mode and reduces the
quiescent current to the minimum value.
