500mA high-PSRR low-IQ low-dropout voltage regulator with enable

The TLV755P is an ultra-small, low quiescent

current, low-dropout regulator (LDO) that sources

500mA with good line and load transient

performance. The TLV755P is optimized for a wide

variety of applications by supporting an input

voltage range from 1.45V to 5.5V. To minimize cost

and solution size, the device is offered in fixed

output voltages ranging from 0.6V to 5V to support

the lower core voltages of modern microcontrollers

(MCUs). Additionally, the TLV755P has a low

IQ with enable functionality to

minimize standby power. This device features an

internal soft-start to lower inrush current, thus

providing a controlled voltage to the load and

minimizing the input voltage drop during start up.

When shutdown, the device actively pulls down the

output to quickly discharge the outputs and

provide a known start-up state.

The TLV755P is stable with small ceramic output capacitors allowing for a small overall solution size. A precision band-gap and error amplifier provides a typical accuracy of 1%. All device versions have integrated thermal shutdown, current limit, and undervoltage lockout (UVLO). The TLV755P has an internal foldback current limit that helps reduce the thermal dissipation during short-circuit events.

The TLV755 is available in the popular WSON,

X2SON, and SOT23-5 (DRV, DQN, and DBV) packages.

This device is also available in a thermally

enhanced SOT23-5 (DYD) package with a thermal pad

that provides significantly reduced thermal

resistance compared to a standard SOT23-5

package.
