一,产品概述(General Description)
CXLD6491 is a dual channel low-dropout regulator that delivers a maximum current
of 1A for each individual output. Typical dropout voltage at 1A load current is
1.3V. Each individual output voltage can be set independently as fixed voltage
(e.g 1.2V,1.8V, 2.5V, 3.3V, 5V) or adjustable output which can provide an output
voltage from 1.25 to 12V with two external resistors. The output accuracy of each
channel is set within 2% by trimming.
CXLD6491 offers thermal shut down and current limit functions to ensure reliability
of device and power system.Package input/output pin configuration can be customized
on demand ( i.e both output can share one input to save one input capacitor and
corresponding PCB real estate).
CXLD6491 is available in lead (Pb)-free ESOP-8(with exposed pad for heat dissipation)
package.
二.产品特点(Features)
Dual channel output with each individual
output can be either fixed output version or
adjustable version.
Maximum output current for each channel is 1A
Range of operation input voltage: Max 12V
Standby current of each output: 2mA (typ.)
Line regulation: 0.1%/V (typ.)
Load regulation: 10mV (typ.)
Environment Temperature: -20°C~85°C
Compatible with tantalum capacitor,
electrolytic capacitor and MLCC.
