FEATURES
DESCRIPTION
Input Voltage Range : 2.6V~6.0V
Adjustable Output Voltage form 0.8V to 5.5V
Dropout Voltage is 380mV at 1A Output Current
Guaranteed 1.2A Output Current
Low Quiescent Current is 50µA (typ.)
Maximum Supply Current in Shutdown Mode <1uA
Fast Transient Response
Under-Voltage Protection
Current Limit and Thermal Shutdown Protection
Short Circuit Current Fold-Back
The APE8969 is a low noise, high output current, low
quiescent current and low dropout linear regulator. The
Device includes pass element, error amplifier, band-gap,
current-limit and thermal shutdown circuitry. The output
current is up to 1.2A, The characteristics of low dropout
voltage and less quiescent current make it good for some
critical current application, for example, some battery
powered devices. The typical quiescent current is
approximately 50µA. In the shutdown mode, the maximum
supply current is less than 1uA. Built-in current-limit, Short
current protection and thermal-shutdown functions prevent
any fault condition from IC damage.
Available in the SO-8 and ESOP-8 Pb-Free Package
