regulators is a low input voltage version of the

• Low I

: 100 μA (max)

popular 1117 voltage regulator.

– 500 times lower than standard 1117 devices

The TLV1117LV is an extremely low-power device

• V

: 2.0 V to 5.5 V

that consumes 500 times lower quiescent current

– Absolute maximum V

= 6.0 V

than traditional 1117 voltage regulators, making it

suitable for applications that mandate very low

• Stable with 0-mA Output Current

standby current. The TLV1117LV family of LDOs is

• Low Dropout: 455 mV at 1 A for V

OUT

= 3.3 V

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

• High PSRR: 65 dB at 1 kHz

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

• Stable with Cost-Effective Ceramic Capacitors:

large currents on the order of 1 A during normal

– With 0-Ω ESR

operation. The TLV1117LV offers excellent line and

load transient performance, resulting in very small

• Temperature Range: –40°C to +125°C

magnitude undershoots and overshoots of output

• Thermal Shutdown and Ovecurrent Protection

voltage when the load current requirement changes

• Available in SOT223 Package

from less than 1 mA to more than 500 mA.

– See Package Option Addendum at end of

A precision bandgap and error amplifier provides

this document for complete list of available

1.5% accuracy. A very high power-supply rejection

voltage options

ratio enables usage of the device for post-regulation

after a switching regulator. Other valuable features

APPLICATIONS

include low output noise and low-dropout voltage.

• Set Top Boxes

The device is internally compensated to be stable

with 0-Ω equivalent series resistance (ESR)

• TVs and Monitors

capacitors. These key advantages enable the use of

• PC Peripherals, Notebooks, Motherboards

cost-effective, small-size ceramic capacitors.

• Modems and Other Communication Products

Cost-effective capacitors that have higher bias

voltages and temperature derating can also be used

• Switching Power Supply Post-Regulation

if desired.

The TLV1117LV series is available in a SOT223

package.

TLV1117LV Series SBVS160A – MAY 2011 – REVISED SEPTEMBER 2011 www.ti.com APPLICATION INFORMATION The TLV1117LV is a low quiescent current linear regulator designed for high current applications. Unlike typical high current linear regulators, the TLV1117LV series consume significantly less quiescent current. These devices deliver excellent line and load transient performance. The device is low noise, and exhibits a very good power-supply rejection ratio (PSRR).

Thermal Information Thermal protection disables the output when the junction temperature rises to approximately +165°C,allowing the device to cool. When the junction temperature cools to approximately +145°C, the output circuitry is again enabled.
