TLV1117LV Series

www.ti.com

SBVS160A –MAY 2011–REVISED SEPTEMBER 2011

1-A, Positive Fixed Voltage, Low-Dropout Regulator

FEATURES

DESCRIPTION

The TLV1117LV series of low-dropout (LDO) linear

regulators is a low input voltage version of the

popular 1117 voltage regulator.

•

1.5% Typical Accuracy

•

Low I_Q: 100 μA (max)

–

500 times lower than standard 1117 devices

V_IN: 2.0 V to 5.5 V

Absolute maximum V_IN= 6.0 V

The TLV1117LV is an extremely low-power device

that consumes 500 times lower quiescent current

than traditional 1117 voltage regulators, making it

suitable for applications that mandate very low

standby current. The TLV1117LV family of LDOs is

also stable with 0 mA of load current; there is no

minimum load requirement, making it an ideal choice

for applications where the regulator is required to

power very small loads during standby in addition to

large currents on the order of 1 A during normal

operation. The TLV1117LV offers excellent line and

load transient performance, resulting in very small

magnitude undershoots and overshoots of output

voltage when the load current requirement changes

from less than 1 mA to more than 500 mA.

•

–

•

Stable with 0-mA Output Current

Low Dropout: 455 mV at 1 A for V_OUT= 3.3 V

High PSRR: 65 dB at 1 kHz

Minimum Ensured Current Limit: 1.1 A

Stable with Cost-Effective Ceramic Capacitors:

–

With 0-Ω ESR

•

Temperature Range: –40°C to +125°C

Thermal Shutdown and Ovecurrent Protection

Available in SOT223 Package

–

See Package Option Addendum at end of

this document for complete list of available

voltage options

A precision bandgap and error amplifier provides

1.5% accuracy. A very high power-supply rejection

ratio enables usage of the device for post-regulation

after a switching regulator. Other valuable features

include low output noise and low-dropout voltage.

APPLICATIONS

•

Set Top Boxes

The device is internally compensated to be stable

with 0-Ω equivalent series resistance (ESR)

capacitors. These key advantages enable the use of

TVs and Monitors

PC Peripherals, Notebooks, Motherboards

Modems and Other Communication Products

Switching Power Supply Post-Regulation

cost-effective,

small-size

ceramic

capacitors.

Cost-effective capacitors that have higher bias

voltages and temperature derating can also be used

if desired.

The TLV1117LV series is available in a SOT223

package.
