TPS7B4255  
SBVS441 – DECEMBER 2022  
TPS7B4255 70-mA, 40-V, Voltage-Tracking LDO With Voltage-Buffering Capability  
1 Features  
3 Description  
Wide input operating voltage range (3 V to 40 V):  
– Absolute maximum input range: –40 V to +45 V  
Wide output voltage range: 2 V to 30 V  
Very-tight, output-tracking tolerance: 5 mV (max)  
Low dropout voltage: 500 mV (max) at 70 mA  
Reverse polarity protection  
The TPS7B4255 is a low-dropout (LDO) voltage-  
tracking regulator, with high tracking accuracy and  
excellent load and line transient response. The device  
is available in a 5-pin, SOT-23 (DBV) package. The  
TPS7B4255 is designed to supply off-board sensors  
in industrial applications such as condition monitoring  
sensor systems. The device provides integrated  
protection features such as reverse polarity, output  
short to supply and ground, 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 survive a 45-V (absolute maximum) input  
voltage during extreme transient events.  
Reverse current protection  
Combined reference and enable input  
Low quiescent current at light loads (100-μA load):  
– 50 μA (max)  
Wide ESR range:  
– Stable with 1-µF to 200-µF ceramic output  
capacitor, 1-mΩ to 3-Ω ESR  
Overtemperature protection  
Output short-circuit protection to ground and  
supply  
Junction temperature: –40°C to +150°C, TJ  
Available in 5-pin SOT-23 DBV package  
Buffers signals up to 1 kHz (see the Signal-  
Buffering LDO section)  
A reference voltage applied at the ADJ/EN pin is  
effectively tracked with high accuracy for loads up to  
70 mA. The high tracking accuracy provides accurate  
power supply to off-board modules and enables  
better accuracy when making measurements using  
ratiometric sensors.  
By setting the ADJ/EN input pin low, the TPS7B4255  
switches to standby mode and reduces the quiescent  
current to the minimum value.  
2 Applications  
Condition monitoring sensors  
Motion detectors (PIR, uWave, and so forth)  
Wired controls  
Telemetry and RTUs  
Robot sensing modules
