AP7350
150mA ULTRA-LOW QUIESCENT CURRENT LDO with ENABLE
Description
NEW PRODUCT
ADVANCED INFORMATION
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 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:
1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.
2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" ,
and Lead-free.
3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl)
and <1000ppm antimony compounds.
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.

6. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only and
functional operation of the device at these conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect
device reliability

pulled to GND.
9. Quiescent current defined here is the difference in current between the input and the output.
10 Dropout voltage is the voltage difference between the input and the output at which the output voltage drops 2% below its nominal value.
11. Test condition: WL-CSP is mounted on PCB (compliant with JEDEC standard).
12. AP7350 is available with 2 options: built-in discharge (AP7350D) and non-discharge (AP7350).
