RT9073A
1μA I_Q, 250mA Low-Dropout Linear Regulator
General Description
Features
The RT9073A is a low-dropout (LDO) voltage regulators ^{ 1μA Ground Current at no Load}
with enable function that operates from 1.2V to 5.5V. It ^{ PSRR = 75dB at 1kHz}
provides up to 250mA of output current and offers low- ^{ ±2% Output Accuracy}
power operation in miniaturized packaging.
 250mA (V_IN ≥ 2.3V) Output Current with EN
The features of low quiescent current as low as 1μA and
almost zero disable current is ideal for powering the battery
equipment to a longer service life. The RT9073A is stable
with the ceramic output capacitor over its wide input range
from 1.2V to 5.5V and the entire range of output load
current (0mA to 250mA).
 Low (0.1μA) Disable Current
 1.2V to 5.5V Operating Input Voltage
 Dropout Voltage : 0.5V at 250mA when V_OUT ≥ 3V
 Support Fixed Output Voltage 0.9V, 1.05V, 1.2V, 1.5V,
1.8V, 1.9V, 2.5V, 2.7V, 2.8V, 2.9V, 3V, 3.3V
 Stable with Ceramic or Tantalum Capacitor
 Current Limit Protection
