Automotive 300mA, 40V, ultra-low-IQ, low-dropout voltage regulator with enable and power good

The TPS7E67-Q1 low-dropout (LDO) linear

voltage regulator is a low quiescent current device designed to connect to the battery in

the automotive applications and supports 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 an 2.8µA quiescent current at

no-load, the device is an good design for powering always-on components such as

microcontrollers (MCUs) and controller area network (CAN) transceivers in standby systems.

The TPS7E67-Q1 supports very tight DC

accuracy of ±1.2% over line, load and temperature range. The device responds quickly to

line, load transients and has fast recovery from cold-crank conditions. The device also

features controlled no-load quiescent current in dropout operation.

The TPS7E67-Q1 is equipped with power-good

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

mechanism for over-current, over-temperature and over-power delivery for reliable operation

of the LDO. The TPS7E67-Q1 is stable with an output capacitor range from 4.7µF to 100µF.

The 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.
