AP7350

150mA ULTRA-LOW QUIESCENT CURRENT LDO with ENABLE

Description

The AP7350 is a low dropout regulator with high output voltage

accuracy. The AP7350 includes a voltage reference, error amplifier,

current limit circuit and an enable input to turn it on/off. With the

integrated resistor network, fixed output voltage versions can be

delivered.

With

its

ultra-low

quiescent

current

and

miniature

package

dimensions, the AP7350 is well suited for low-power handheld,

wearable devices, and other battery-operated devices requiring an

extended time period until new battery replacement.

The AP7350 is available in the wafer level chip scale X2-WLB0606-4

package. This part is one of the smallest LDO footprints in the

industry allowing for the use of a bare minimum of board space within

the application.

Notes:

4. X5R- and X7R-type capacitors are suggested due to their minimal variation in value and ESR over temperature.

5. Avoid light exposure of the chip scale package to maintain the expected electrical performance and functionality of the AP7350.
