AP7348 4 CHANNEL 300mA HIGH PSRR LOW NOISE LDO WITH ENABLE Description Pin Assignments
The AP7348 is a 4 channel low dropout regulator with high output voltage accuracy, low RDS(ON), high PSRR, low output noise and low
(Top View)
quiescent current. This regulator is based on a CMOS process. The AP7348 includes two voltage references, and four channels with each having an error amplifier, foldback current limiting, a discharge circuit and an independent resistor network to determine the fixed
T
output voltage. The over temperature sensing is for each channel with
C
all 4 channel being disabled during a temperature fault condition. The
U
device has two enable inputs with EN1 controlling both VOUT1 and
D
VOUT3 leaving VOUT2 and VOUT4 to be controlled by EN2. During
O
disable the two associated channels will discharge.
R P
With its low power consumption and line and load transient response,
W
the AP7348 is well suited for low power handheld communication
E
equipment.
X1-DFN161 N 2-8 (Type B)
The AP7348 is provided in the X1-DFN1612-8 (Type B) package
Applications
allowing for a small footprint and a dense PCB layout. Smart Phone/Tablet RF Supply
Features
Cameras Low VIN and Wide VIN Range: 1.7V to 5.25V Portable Video Each Channel Output Current: 300mA Portable Media Player VOUT Accuracy ±1% Wireless Adapter Ripple Rejection 75dB at 1kHz Wireless Communication Low Output Noise, 60µVrms from 10Hz to 100kHz Total 4 Channel Quiescent Current is Typically 160µA VOUT Fixed 1.2V to 3.6V
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative. https://www.diodes.com/quality/product-definitions/
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.
