A7336
600mA STEP-DOWN DC-DC + DUAL 300mA CMOS LDO
POWER MANAGEMENT UNIT (PMU)
DESCRIPTION
The A7336 is a complex power management,
which can provide two roads of low-noise
high-speed LDOs and high efficiency reached
95% of the DC-DC buck. As the use of CMOS
process realization of the work of the chip
consumes very little current, the internal use of
low-resistance, makes the LDO's output current of
up to 300mA, DC-DC load current of up to 600mA.
A built-in low on-resistance transistor provides a
low dropout voltage and large output current, a
built-in overcurrent protector prevents the load
current from exceeding the current capacitance of
the output transistor, and a built-in thermal
shutdown circuit prevents damage caused by the
heat.
FEATURES
Highly Accurate : LDO : ± 2%, DC-DC :± 2.5%
Output current Range : LDO:300mA
DC-DC:800mA
High Ripple Rejection 70dB@(1KHz,50mA)
Low Power Consumption 150μA (TYP.)
Shutdown Current less than 0.1μA
Internal protector current limiter、short protector
and thermal shutdown protector
Available in DFN10(3x3) package
APPLICATIONS
