GENERAL DESCRIPTION
The ACT670_ MobileLDOTM series products
are high performance low dropout voltage
regulators designed for portable applications with
very low quiescent current (23µA) and dropout
voltage (110mV at 150mA).
The ACT670_ LDOs have typical current limit
of 450mA and are available in high accuracy
(1.5%) output voltages from 1.5V to 5V in 50mV
increments. These products feature thermal
shutdown protection and current limit with
fold-back in short circuit.
The ACT6700 is available in the SOT23-3
and SOT89-3 packages. The ACT6701 is
available in the SOT23-5 package and includes a
power-good indicator output. The ACT6702 is
available in the SOT23-5 package and includes a
low noise bypass pin for low noise applications.
These products are ideal for portable information
devices, cellular phones, and other battery
powered applications.
