150mA LDO Regulator with POG
General Description
The RT9181 is a low dropout voltage regulator with
an output 2% accuracy and supply a continuous
150mA current within operating range from a +3V to
+5.5V input. The power good function monitors the
output voltage and indicates by pulling low the power
good output (open drain).
The RT9181 requires a small output capacitor with
low ESR for stabilizing output voltage. The device
also minimizes output overshoot during power up.
The RT9181 uses an internal PMOS as the pass
device, which consumes 160
μ
A supply current
independent of load and dropout conditions. The CE
pin controls the output and consumes no input bias
current. Other features include current limiting, over
temperature protection, and under voltage lockout.
