TLV767-Q1 1-A, 16-V Linear Voltage Regulator

1 Features

3 Description

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.

•

AEC-Q100 qualified for automotive applications:

–

Temperature grade 1: –40ºC to +125ºC, T_A

Junction temperature: –40ºC to +150ºC, T_J

•

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 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, 100-mV steps)

•

1% output accuracy over load and temperature

Low quiescent current (I_Q):

–

50 µA (typ) with no load

3 µA (max) when disabled

The TLV767-Q1 has a 1% output accuracy that is

required for powering digital loads with tight supply

requirements.

•

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

The internal soft-start circuit reduces inrush current

during startup, thus allowing for smaller input

capacitance.

Package: 8-pin, 3-mm × 3-mm WSON with

wettable flanks

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.

–

Low thermal resistance (R_θJA): 56.2°C/W

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.
