RT9014/A-
General Description
RT9014/A is a dual channel, low noise, and low dropout
with the sourcing ability up to 300mA, an open drain driver
and power-on reset function. The open-drain output is
capable of sinking 150mA for LED backlighting
applications.
The range of output voltage is from 1.2V to 3.6V by
operating from 2.5V to 5.5V input.
RT9014/A 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.
RT9014/A is short circuit thermal folded back protected.
RT9014/A lowers its OTP trip point from 165
°
C to 110
°
C
when output short circuit occurs (V
OUT
< 0.4V) providing
maximum safety to end users.
RT9014/A can operate stably with very small ceramic
output capacitors, reducing required board space and
component cost. RT9014/A is available in fixed output
voltages in the WDFN-1
0L 3x3 package.
