TLV767-Q1  
SBVS381A – APRIL 2020 – REVISED DECEMBER 2020  
TLV767-Q1 1-A, 16-V Linear Voltage Regulator  
1 Features  
3 Description  
AEC-Q100 qualified for automotive applications:  
The TLV767-Q1 is a wide input linear voltage  
regulator supporting an input voltage range from 2.5 V  
to 16 V and up to 1 A of load current. The output  
range is from 0.8 V to 12 V or up to 14.6 V with the  
adjustable version.  
Temperature grade 1: –40°C to +125°C, TA  
– Junction temperature: –40°C to +150°C, TJ  
Input voltage range: 2.5 V to 16 V (18 V max)  
Output voltage range:  
The wide input voltage range makes the device a  
good choice for operating from transformer secondary  
windings and regulated rails such as 10 V or 12 V.  
Additionally, the wide output voltage range allows the  
device to generate the bias voltage for silicon carbide  
(SiC) gate drivers and microphones as well as power  
microcontrollers (MCUs) and processors.  
– 0.8 V to 14.6 V (adjustable)  
– 1.2 V to 12 V (fixed)  
1% output accuracy over load and temperature  
Low quiescent current (IQ):  
– 50 µA (typ) with no load  
– 4 µA (max) when disabled  
High PSRR: 70 dB at 1 kHz, 46 dB at 1 MHz  
Internal soft-start time: 500 µs (typical)  
Fold-back current limiting and thermal protection  
Stable with a 1-µF or larger capacitor  
Package: 8-pin, 3-mm × 3-mm WSON with  
wettable flanks  
The TLV767-Q1 has a 1% output accuracy that is  
required for powering digital loads with tight supply  
requirements.  
The internal soft-start circuit reduces inrush current  
during startup, thus allowing for smaller input  
capacitance.  
– Low thermal resistance (RθJA): 51.9°C/W  
Wide bandwidth PSRR performance is greater than  
70 dB at 1 kHz and 46 dB at 1 MHz, which helps  
attenuate the switching frequency of an upstream  
DC/DC converter and minimizes post regulator  
filtering. The high ripple rejection from 20 Hz to  
20 kHz make the device a good choice for powering  
audio components.  
2 Applications  
DC/DC converters  
Inverter and motor controls  
On-board (OBC) and wireless chargers  
Automotive head units  
The TLV767-Q1 is available in a 8-pin, 3-mm × 3-mm  
VSON (DRB) package with wettable flanks and low  
thermal resistance.
