主要参数：耐压40V,电流250mA，PSRR=80dB,SOT23-3/TSOT23(厚度0.75mm）封装，低压差！
DESCRIPTION
The JX6402 ultra-low quiescent current regulator
features low dropout voltage and low current in the
standby mode. With less than 2.5μA quiescent current at
no load, the JX6402 is ideally suited for standby
micro-control-unit systems, especially for always-on
applications like E-meters, fire alarms, smoke detectors
and other battery operated systems. The JX6402 retains
all of the features that are common to low dropout
regulators including a low dropout PMOS pass device,
short circuit protection, and thermal shutdown.
The JX6402 has a 40
V maximum operating voltage
limit, a -40°C to 125°C operating temperature range, and
±2% output voltage tolerance over the entire output
current, input voltage, and temperature range. The
JX6402 is available in a SOT89-3 through-hole and
SOT23-5, SOT23-3 surface mount packages.
