TL1963A-Q1 1.5-A Low-Noise Fast-Transient-Response Low-Dropout Regulator

1 Features

3 Description

The TL1963A-Q1 device is a low-dropout (LDO)

regulator optimized for fast transient response. The

device can supply 1.5 A of output current with a

dropout voltage of 340 mV. Operating quiescent

current is 1 mA, dropping to less than 1 µA in

shutdown. Quiescent current is well controlled; it does

not rise in dropout as it does with many other

regulators. In addition to fast transient response, the

TL1963A-Q1 regulators have very low output noise,

which makes them ideal for sensitive RF supply

applications.

Qualified for Automotive Applications

•

AEC-Q100 Test Guidance With the Following:

–

Device Temperature Grade 1: –40°C to 125°C

Ambient Operating Temperature

–

Device HBM ESD Classification Level 2

Device CDM ESD Classification Level C6

•

Optimized for Fast Transient Response

Output Current: 1.5 A

Dropout Voltage: 340 mV

Output voltage range is from 1.21 V to 20 V. The

TL1963A-Q1 regulators are stable with output

capacitors as low as 10 µF. Small ceramic capacitors

can be used without the necessary addition of ESR,

as is common with other regulators. Internal

Low Noise: 40 µV_RMS(10 Hz to 100 kHz)

1-mA Quiescent Current

No Protection Diodes Required

protection, current limiting, thermal limiting, and

reverse-current protection. The devices are available

in fixed output voltages of 1.5 V, 1.8 V, 2.5 V, and

3.3 V, and as an adjustable device with a 1.21-V

reference voltage. The TL1963A-Q1 regulators are

available in the 5-pin TO-263 (KTT) package.
