Texas Instruments TPS7E67-Q1 LDO Linear Voltage Regulators
Texas Instruments TPS7E67-Q1 Low-Dropout (LDO) Linear Voltage Regulators are low-quiescent-current devices designed to connect to the battery in automotive applications and support a wide input voltage range from 3V to 40V. The wide output range is from 1.2V to 38V for the adjustable configuration and 1.8V to 12V for the fixed configuration, and up to 300mA of load current. With only a 2.8µA quiescent current at no load, the device is well-suited for powering always-on components such as microcontrollers (MCUs) and Controller Area Network (CAN) transceivers in standby systems.
The TPS7E67-Q1 supports a very tight DC accuracy of ±1.2% across line, load, and temperature ranges. The device responds quickly to line and load transients and recovers quickly from cold-crank conditions. The device also features controlled no-load quiescent current in dropout operation.
The TPS7E67-Q1 is equipped with a power-good signal having delay and de-glitch features for monitoring of the output voltage. The power-good delay can be adjusted by using external capacitors. The LDO has built-in protection mechanisms for overcurrent, overtemperature, and over-power delivery to ensure reliable operation. The TPS7E67-Q1 is stable with an output capacitor range of 4.7µF to 100µF.
The Texas Instruments TPS7E67-Q1 is available in a 2.0mm × 2.0mm, 6-pin WSON (wettable flank) (DRV-WF), 3.0mm × 4.9mm, 8-pin HVSSOP (DGN), and 4.90mm × 6.00mm, 8-pin HSOIC (DDA) package for fixed and adjustable outputs.
