AP7351D
150mA ULTRA-LOW QUIESCENT CURRENT LDO WITH ENABLE
Description
The AP7351D is a low dropout regulator with high output voltage
accuracy. The AP7351D 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, the AP7351D is well suited for
low-power handheld, wearable devices, and other battery-operated
devices requiring an extended time period until new battery
replacement.
The AP7351D is available in the X2-DFN1010-4 (Type B) and SOT25
packages.

Notes:
1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant.
2. See https://www.diodes.com/quality/lead-free/ 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.

Enable Pin
EN This pin should be driven either high or low and must not be floating. Driving this pin high
enables the regulator, while pulling it low puts the regulator into shutdown mode

NC No connection for fixed VOUT versions.
In PCB layout, prefer to use large copper area to cover this pad for better thermal dissipation,
Exposed Pad then connect this area to GND or leave it open. However, do not use it as GND electrode
