General Description
RT9012 is a dual channel, low noise, and low dropout with
the sourcing ability up to 300mA and power-on reset
function. The range of output voltage is from 1.2V to 3.6V
by operating from 2.5V to 5.5V input.
RT9012 offers 2% accuracy, extremely low dropout voltage
(240mV @ 300mA), and extremely low ground current,
only 27
μ
A per LDO. The shutdown current is near zero
current which is suitable for battery-power devices. Other
features include current limiting, over temperature, output
short circuit protection.
RT9012 is short circuit thermal folded back protected.
RT9012 lowers its OTP trip point from 165
°
C to 110
°
C
when output short circuit occurs (VOUT < 0.4V) providing
maximum safety to end users.
RT9012 can operate stably with very small ceramic output
capacitors, reducing required board space and component
cost. RT9012 is available in fixed output voltages in the
WDFN-8L
2x2 package.
Note :
Richtek Pb-free and Green products are :
`
RoHS compliant and compatible with the current require-
ments of IPC/JEDEC J-STD-020.
`
Suitable for use in SnPb or Pb-free soldering processes.
`
100% matte tin (Sn) plating.
