TLV766-Q1 500-mA, 16-V Linear Voltage Regulator
1 Features
3 Description
•
AEC-Q100 qualified for automotive applications:
The TLV766-Q1 is a wide input linear voltage
regulator supporting an input voltage range from 2.5 V
to 16 V and up to 500 mA 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 TLV766-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.
